Singapore advertises Cord Blood Stem Cell Banking (Part 2)

A Cordlife ad was timed right after the appearance of the Singapore Cord Blood Bank's news article - and that wasn't a coincidence.



In fact this latest ad was a masterful stroke of PR execution, citing rates of stem cell usage from the SCBB's own article and adding on the other applications worldwide. It highlights what families ought to store their own babies stem cells for their own use and advocates that private cord blood banking ensures 100% accessibility to your own banked cells.


If you can't see the facts and figures in the picture above here's the wording on the left:

Incidence rate of stem cell treatable diseases:

6 people are diagnosed with blood related diseases in Singapore every day
2 of the top 10 cancers afflicting Singaporeans are Lymphoma and Leukemia
1 in 500 babies are diagnosed with Cerebral Palsy
2 children are diagnosed with Type 1 diabetes in Singapore every month
80 diseases are now treatable using cord blood stem cells and possibly more in the future.

Chances of using stem cells:

1 in 217 chance that a person may need cord blood stem cells for treatment in their lifetime
80 cord blood units were released for transplants and therapeutic applications by Cordlife.

Higher chance of finding a match within the patient's family:

70% of cord blood transplants by Cord Blood Registry were from siblings. 30% was for self use.
75% chance of a sibling match
25% chance of a 100% match between siblings. A perfect match is required for bone marrow transplants but not in cord blood transplants.
$26,000 is the minimum cost of buying back a donated cord blood unit if it is still in storage.

Availability of stem cells:
50% of all donations to a public cord blood bank are normally discarded for various reasons
100% - your accessibility to your privately stored cord blood stem cells.



All true of course, and I've always wondered this: Singapore's birth rate is at thirty to forty thousand per year and it's conceivable that there may be a time when every Singaporean has his or her cord blood stem cells banked in the future. Given Singapore's small population, its probably the best place imagining that this could happen, a very accessible and heterogenous database which could be leveraged for treatment and if consented, research for autologous regenerative purposes.


Now that would be really cool.


** Unfortunately the online version of this article isn't the full version that was published in print.


Malaysian Medical Advertising Regulations prohibits any form of advertising using terms ranging from "treatment" to "Thalassemia" so it is virtually impossible for us to advertise as our neighbors did (all brochures and the stem cell organization are required to be separately licensed by the Ministry of Health, so make sure the stem cell bank you're talking to has all the documented approvals and are operating within legal guidelines).

However, since all of it was factual and cited from peer-reviewed journals and both local and international news articles, its good to share these statistics with our patient base here too.

Cord Blood Stem Cells to treat Breast Cancer?

In a groundbreaking study (click on title for abstract), just published and not yet picked up by the media, researchers from the Departments of Anatomy and Physiology and Diagnostic Medicine/Pathobiology at the College of Veterinary Medicine in Kansas State University in Kansas, reported in the February edition of the journal "Cancer Research" that "Rat Umbilical Cord Stem Cells Completely Abolish Rat Mammary Carcinomas with No Evidence of Metastasis or Recurrence 100 Days Post-Tumor Cell Inoculation."

What they did was that they transplanted Fisher 344 rat-derived mammary adenocarcinoma cells (Mat B III-breast cancer) orthotopically (meaning into the breast of the female rats) into syngeneic (related) F344 rats with an intact immune system. Then they injected rat umbilical cord matrix stem (rUCMS) cells derived from Wharton's jelly, intratumoral (i.t. meaning into the tumor) or i.v. (into the veins of the animals) 4 days later.

Then they compared the tumor attenuation effect (meaning how the tumor was suppressed-fought / extinguished) at day 14 after the injection in the tumor or in the veins in cord blood stem cell-transplanted rats compared with sham-transplanted rats (meaning animals that received an injection but no stem cells). What they saw was amazing!

Unmodified rUCMS cord blood stem cell-transplanted rats showed complete regression of tumors to undetectable levels by 34 to 38 days with no evidence of metastasis or recurrence 100 days post-tumor cell inoculation (injection in the tumor). They concluded that their findings suggest that "unmodified human UCMS cells (cord blood stem cells from the Wharton's jelly of the umbilical cord) could be used for targeted cytotherapy for breast cancer".

Well, this is REALLY something to look out for, isn't it?! [Cancer Res 2009; 69(5): 1815-20]

UK-Singapore Stem Cell Symposium I


Just to remind the world that the UK isn't behind in science (vis-a-vis the US), the British High Commission probably decided that this exhibition panel was important to remind everyone of the UK's key scientific achievements.

So, if you didn't already know or can't read the words in the picture, here's three that you might have confused as a US invention...

UK GREATS
1953: Discovery of structure of DNA
1978: Birth of first test-tube baby
1985: Discovery of hole in Ozone layer
1990: Invention of World Wide Web (bet you all thought this was from the US!)

Anyway, I mentioned in my last post that I'd tell you a bit about what I learned in the symposium. My apologies for the delayed write up.

The first lecture after lunch was by Professor Tariq Enver, Professor of Stem Cell Biology at Oxford and Director of Stem Cell Research at the MRC's Molecular Haematology Unit in the Weatherall Institute for Molecular Medicine.

Prof. Enver's talk was of interest to me for 2 reasons - inspiring content AND all the key ingredients of a good presentation:

1. Clinical relevance (patient's photos to inspire the right emotional context)
2. Clear introductory statistics for the uninitiated
3. Direct genetic implications of the research
4. A happy conclusion (very important)


WHAT IT WAS ABOUT

The story begins with the introduction of stem cells and their existence in babies' blood. The first question he posed to the audience was whether anyone knew what a "Guthrie card" was (when a baby is born, a small heel prick is performed to obtain the baby's blood, which is stained on a filter paper- known as a Guthrie card- and used to test for inborn metabolic diseases). Prof. Enver suggests that Guthrie cards can be kept for extended periods of time so that if a child is later found to develop certain types of leukemia, it would be possible to identify whether the indications of leukemia were there at birth.


WHY IS THIS IMPORTANT?

The reason why it is useful to know whether the leukemic cells are present at birth, is because if the cells are present at birth, doctors may choose to treat the patient with different medications as leukemic cells (which behave like stem cells) have different chemo-sensitivities in children. Leukemic cells from birth may require more specific and less intensive drugs than adult patients.


At this point, I feel that it is important to point out the difference between "stem cells" and what is popularly termed "cancer stem cells".

Stem cells are cells which exist in the body and are responsible for continuous maintenance of the body and a controlled replacement of our cells and tissues. The stem cells are known to be "relatively immortal" (ie they live a far longer lifespan than our normal cells, which may die after 7-90days) and are key to our existence and survival of our blood and immune systems etc.

Cancer stem cells however, are like other cancers -cells gone wrong- except that the cell that has gone wrong is the stem cell. Hence, the cancer stem cell does not make other tissues and does not replace cells like it should. It merely makes more of itself, which isn't useful under the normal circumstances.


So, a pertinent question to ask is how do you know a stem cell from a cancer stem cell? Well, Prof Enver believes that there is a lot of talk about "markers" for stem cells, but there is no doubt that these markers have a long way to go in being defined and that the best way to know is to conduct functional studies (ie, to see how the cells really work in real life).


REAL LIFE SCENARIO

A pair of very beautiful twin girls from Bromley a city in Kent, were the subjects of the study. According to the news story, which was reported in January this year, Olivia Murphy developed acute lymphoblastic leukemia (ALL) when she was 2 years old, while her twin sister Isabella remained healthy. I'm not exactly sure how the case came to Prof. Enver's attention at the MRC (I wanted to ask him but didn't get a chance) but he and his group ended up researching why one of the twins developed the disease while the other remained healthy. Prof. Enver's team elucidated that both twins carried a gene that pre-disposes them to developing the ALL, but while Isabella only had one hit to her gene, Olivia had two hits which resulted in cancer development (cancer usually results from several mutations to certain genes which allow the cells to grow uncontrollably).

They proved to be the perfect research subjects to understand if genetics had a pivotal role in the stem cells, which could already be susceptible to chance changes after birth. The aim of the research, was to discover where the point of change was that resulted in the cancer, and whether it would be possible to design a method to protect the susceptible genes (prevention) or necessary drugs which would target the cancer cells.

There was a more detailed write up which describes how the twin's parents brought Olivia in for fever which the doctors had then thought was tonisilitis. The parents insisted on a blood test and were given the ALL diagnosis. Fortunately, Olivia's cancer responded well to the chemotherapy and was a success, but not without side effects.

The chemotherapy was so strong that her immune system was damaged and she suffered six attacks of shingles (chicken pox relative) which infected her eye and blinded it. In the course of research, Prof. Enver's team took regular samples of both the girls' blood and the doctors will screen Isabella regularly to monitor any signs of the 'second hit'.


OPTIMISM FOR TARGETING PRE-CANCER CELLS

According to Prof. Enver, as the total cancer relies on less than one per cent of the cancer generating cells to maintain the disease, this offers a unique opportunity to develop better drugs to kill off this one per cent of cells. He was quoted saying that there could be a day where the prevention of leukemia would be possible as the pre-leukemia cells could be eliminated at the source, potentially curing 90% of the cases detected.

However, no medical procedure is risk free and the strong chemotherapy may result in the death of 1-2% of cases treated. And for those couples with identical twins, you might like to know that nine out of ten children who have an identical twin with leukemia do not develop the disease.

That means that Isabella's chances of staying cancer free remains pretty high. :)

Singapore's Successful Double Cord Blood Stem Cell Transplant

Just when you've heard from other news sources that:
a) cord blood stem cells are useless;
b) that you'll never ever need it;
c) that cord blood units contain too little to be used in a transplant or;
d) that it is only used in cases of small children

Bravo to Singapore's marrow transplant doctors for their successful case of 19 year-old Nanyang Polytechnic student Candy Yeow. She had Philadelphia positive acute lymphoblastic leukemia which had very poor prognosis of survival. However, she was very lucky because the medical team was able to find 2 HLA matching (or near matching) units of cord blood stem cells from an overseas cord blood bank. Her transplant went well and at her one-year transplant anniversary, she's in complete remission and off all immuno-suppressants.

Her doctor at the Singapore General Hospital Dr. Mickey Koh was quoted as saying that a single unit of cord blood didn't have enough stem cells for the transplant and hence they went for two combined units in order to achieve the requisite number of stem cells for the patient.

Hence, if you're wondering whether cord blood stem cells can be used for an adult, it depends on how many stem cells were collected in the first instance and if it isn't, at least you're halfway there with one unit. The odds of finding one matching unit is challenging enough, but two matching units like what Candy has here is almost a miracle*.


*Apart from just finding the right matching cord blood stem cell units, the medical care provided to ensure successful recovery is equally important and not to be taken for granted.


WHY CANDY HAD TO HAVE A STEM CELL TRANSPLANT FOR HER CONDITION

From Blood Journal:

Philadelphia chromosome (Ph1)-positive acute lymphoblastic leukemia (ALL) has a poor prognosis when treated with conventional chemotherapy. We analyzed the outcome of 67 HLA-identical sibling bone marrow transplants (BMTs) for Ph1-positive ALL reported to the International Bone Marrow Transplant Registry (IBMTR). Twenty-one of 67 (31%) transplant recipients survived in continuous complete remission more than 2 years after transplant. Two-year actuarial probabilities (95% confidence interval) of leukemia-free survival were 38% (23% to 55%) for 33 patients transplanted in first remission, 41% (23% to 61%) for 22 patients transplanted after relapse, and 25% (9% to 53%) for 12 patients failing to achieve remission with conventional chemotherapy. These data indicate that transplants are effective treatment for Ph1- positive ALL.


Also for the record, there is little indication that propensity for ALL is passed on from parents to children.

First Ever Beijing Stem Cell Donor for Taiwanese Recipient

Despite any political maneuvering between China and Taiwan, it is articles like these (1, 2) that bring our minds back to the basics- which is that geopolitics aside, our genetic heritage links us and binds us eventually to a common fate.

Additionally, stem cell resources will always reside with the size and diversity of the population, hence China with more than 1.3 billion is a stem cell treasure trove for chinese people all over the world if we are able to thoroughly profile and screen the stem cells.


The article which I noted a while ago (sorry, it's a late comment, but I thought it worthwhile) reports the first time that stem cells were matched from a patients in Taiwan to donors in Beijing*. The two profiled donors were Ms. Hang from Jiangsu province and Ms. Xiaoyan from Hunan province. (click here if you'd like to know where the provinces are in relation to Beijing)

They were brought to Beijing and their stem cells were mobilized from their bone marrow to the bloodstream (you can read more on mobilization and collection here) and their stem cells collected via apheresis. Their stem cells were subsequently transported to Taiwan for the transplantation.

The second article provides a little more detail on the donors and their perceptions of stem cell harvesting and donation.

Ms. Hang who is a youthful 36 year-old is a registered blood donor who has donated blood several times in her life. Apparently, a marrow bank was established in her home province in 2003 but few people registered as donors. Ms. Hang signed up as a donor in the registry not only because her employer, Amway urged all employees to do so, but also because she saw it as "an opportunity to help others... why not do it?"

Amway's staff registration yielded 1,500 new potential donors and they report that 4 of them have already been called on as donors.

Ms. Hang's father is a doctor and said that the process of mobilizing and collecting stem cells was harmless and supported her decision to donate. The recipient was a 16 year-old girl and I hope that they collected as many stem cells as they could and that the patient has recovered.



*Taiwan has exported stem cells obtained from donor's cord blood, bone marrow and peripheral blood to patients all over the world. Cord blood stem cells obtained from a private company that facilitates the storage facility for databasing and sale, Stemcyte incur a charge of between RM 100,000 to RM 150,000 per unit (they have released in excess of 250 cord blood stem cell units). Some patients have also withdrawn 2 cord blood stem cell units to use in a double transplant when one unit is insufficient.

Malaysian patients have accessed this facility many times and have been able to find successful matches which has allowed life-changing stem cell transplantation to proceed.

Credit also goes to the Tzu Chi Taiwan Marrow Donor Registry, the third largest of its kind in the world, which has made over a hundred matches for mainland patients and patients in South East Asia.

Adult Patient gets Cord Blood Stem Cells for Transplant

I found this video pretty interesting as the interviewee highlights the plight of many patients today who aren't told or advised about the uses of cord blood stem cells. Eric Drew was only told about bone marrow transplantation (but didn't have any full siblings) and wasn't informed of any other options. It was on his own initiative that he found out about cord blood stem cells and followed up with a successful transplant. So, another adult has been successfully cured with cord blood stem cells... don't let anyone tell you that cord blood stem cells aren't useful for adults.

At StemLife, we do advise parents that while their children may not need it within the first few years of their life (touch wood), it is affordable and reasonable to bank the stem cells so that the resource is available for possible later use.

The video is a little bit heavy to download but its worth hearing his optimism and it's good listening to a patient who has been through the procedure.

Amelia Worth has passed away awaiting her Stem Cell Transplant

I blogged about Amelia's condition a while ago and was very sad to see this recent article published saying that she had passed away.

Apparently she won her fight to find a matching donor, but not in time for a the transplant to be performed. She had her chemotherapy, had an infection and succumbed in a coma.

For what its worth, I hope she was not in pain.

And I hope that people will consider banking their stem cells just in case they need it, not because I'm promoting the service but really because when you read stories like hers, you really wish that there was something that you could have done earlier. :(

Read the story here.

Celebrating 2007, 25th Stem Cell Anniversary & Life-saving Siblings

Happy 2007 to all Stem Cell bankers and StemLife blog readers!I wrote this entry just before midnight asian time and thought it would be nice to end the year of 2006 with a happy stem cell update and another one of hope to start 2007. I would like to start this entry by acknowledging the importance of siblings in enabling successful stem cell transplants.

SIBLINGS ARE SO IMPORTANT

The first story is a lovely one about a sister who donated her bone marrow stem cells to her brother 25 years ago, which saved his life from leukemia. The procedure was performed as one of the pioneering transplants at Hammersmith hospital in London, to think that transplant procedures are considered almost standard at most major hospitals offering cancer therapy today.

Paul Rosen who is now 51 now has 2 grown up children and a successful career as a accountant. His sister Helen, who is six years older than he is, are now sharing their success story to encourage others to also help their siblings if the need should arise.

Unfortunately, at the same time as Paul was in hospital, his friend who was also warded in for the same condition refused to ask his sister to donate (presumably they were told that the procedure was experimental) and they held off the procedure for 2 years. However, in the 2 years, his condition deteriorated and by the time he agreed to undergo the transplant, he passed on.

While there are public registries of bone marrow donors and umbilical cord blood stem cell units, there are many people who are still unable to find a match. StemLife is offering to provide a practical solution to this through stem cell banking for individuals who can store their stem cells for later use.

I found an interesting blog from a leukemia transplant patient who underwent a similar procedure to Paul Rosen at Hammersmith hospital. Check out Sandy Craine's blog.


In a separate story, a little girl of 4, Kayla Smith is searching for matching stem cells which will allow her to undergo a stem cell transplant for her congenital condition- sickle cell anemia (have a look at this site to see what nasty symptoms result from sickle cell anemia). She's already suffered 2 strokes due to the condition which puts her at risk of a potential major stroke. She receives monthly blood transfusions which take several hours, but recently, the blood transfusions have lost their effectiveness and she needs a stem cell transplant to really bring about a cure.

Kayla has a brother but his stem cells were not a match.

Kayla's doctor is a paediatric hematologist and oncologist by the name of Julie Panepinto, and she said that the transient ischemic attacks that her patient has been experiencing since the age of two indicates that the blood transfusions are no longer effective. Her most recent stroke and seizure was when she was nearly three. As a result of these ischemic attacks, a large part of her brain has been affected and Dr. Panepinto suspects that Kayla's learning ability may have been severely compromised.

Initially, the doctors thought that they had found a good bone marrow match, but upon more detailed tests, the match was found to be too imperfect for the transplant. Kayla is still waiting for that perfect match... but in the meantime, I'm wondering if the parents are game to try what others in the same position have done before- concieve another child with a perfect HLA match to Kayla, but without the disease. The UK courts permitted it, probably on grounds that the parents would be able to care and love the child without any economic or emotional problem. This may be an option to explore, so that a stem cell transplant can be performed, before another more severe stroke happens.


StemLife provides stem cell banking services from cord blood and adult peripheral blood. While sickle cell anemia is not common genetically within the Malaysian population, another genetic blood disorder which results in similar symptoms and has a wide prevalence is Thalassemia beta major. Palliative care, as in the case of Kayla, is blood transfusion and chelation therapy but not without its side effects on other organ functions. A stem cell transplant currently provides the only means for a cure and a chance at life without continuous daily medication.

With a view to benefit a diverse Malaysian community and provide accessible services to those who need it most, StemLife takes every unit banked very seriously and endeavors to make a real difference in making stem cell transplantation a reality for StemLife family bankers today.


ps. If you'd like to read a short overview of stem cell transplantation for blood disorders, have a look at this site.


pps. Interestingly, the article on Kayla also mentions little Kailee Wells, a 9 year old adopted chinese girl who suffered from severe aplastic anemia. The update on her case is that she required a second transplant after the first one was unsuccessful. However, despite the second transplant, Kailee's cell counts continued to decline, but fortunately, her donor from China has agreed to donate more marrow to provide a boost via a straightforward stem cell infusion without chemotherapy (chemo is required only to kill cancerous cells or defective stem cells).

11 Year-Old Malaysian Girl Provides Stem Cell Match for Brother With Acute Myeloid Leukemia

Its not often that we get news on Stem Cells in Malaysia but I do think that ever since we've started highlighting the applications, many more doctors are beginning to speak out about the important work that they do.

I read yesterday in the Star about a little girl by the name of Siti who has undergone a peripheral blood stem cell harvest to help her 17 year old brother Muhammad, who was diagnosed 5 months ago with Acute Myeloid Leukemia (see Angel's story).

You can read Siti's story here but I thought that it would be good to pick up on a few key points in the article which supports our preemptive peripheral blood and cord blood stem cell banking service. Its all about providing options for yourself in the future.

The treating haematologist Dr. Ng Soo Chin describes the chances of finding a match within the family:


STEM CELL MATCH

"A blood test, called HLA typing, is done to test whether a potential donor is a match. “There is a 25% chance of a sibling being a match to the patient,” Dr Ng notes. However, parents and half-siblings are usually not such good matches. "

I thought that it was a very well written article and Dr. Ng points out clearly that bone marrow harvesting- which is painful and very unpopular- is on a decline and that now peripheral blood stem cell harvesting is the way to go.


NO MORE PAINFUL BONE MARROW

"Not too long ago, the idea of donating stem cells frightened many people, not least because it required general anaesthesia and painful extraction of the stem cells directly from the bone marrow. Now, 90% of stem cell transplants use peripheral harvesting, instead of bone marrow,” Dr Ng assures. Peripheral harvesting means that the stem cells are collected from the blood stream in a procedure called apheresis. "

Peripheral blood stem cell collection is much preferred over bone marrow because doctors can be assured of a decent harvest. Very often bone marrow extractions require a lot of manipulation and may not obtain a reliable amount of cells for a transplant. Clotting of the blood is often one of the problems, a long with trauma bleeding, anaesthetic risk and patient discomfort.


PERIPHERAL BLOOD STEM CELLS - A VERY SAFE PROCEDURE

Dr. Ng says: “It’s like blood donation, except that it takes longer. However, the actual volume of blood that you donate is only about 50-100ml,” he explains, insisting that this is a very safe procedure.

And he also describes why using one's own stem cells are preferred, although this option is not always available:

When the patient is both the donor and the recipient of the stem cells, there are fewer risks involved – namely, no graft-versus-host disease, no immunosuppression needed and fewer infections.


TRANSPLANT ALREADY PERFORMED

Siti's stem cells had already been transplanted into her brother at the time of the publication and I do hope that he recovers and tells his story so that others may also know how a matching set of stem cells was critical in making the procedure possible.


StemLife provides stem cell collection and banking from the peripheral blood for healthy individuals and families. We also provide services for patients seeking treatment in collaboration with qualified medical specialists.

Please feel free to call us for a no obligation consultation at +603 2163 8800 or at 012 2050 165. We'd be happy to help.

Adult Stem Cells Help Repair Radiation Damaged Tissue


I was excited to see this news release by the Director of the Clinic for Radiation Therapy as a result of the 25th Annual Congress of the European Society for Therapeutic Radiology and Oncology (ESTRO) held in Germany on the 9th of October.

In a nutshell, adult stem cells when infused after radiation therapy for cancers helps to alleviate the side effects of mucosa (think nasal passages, throat, digestive tracts etc) and skin.


The news release was so clear in its message that I'd like to post it almost in its entirety:

"Stem cell research will have many consequences for various fields of medicine", predicts Catherine Verfaillie, Director of the Stem Cell Institute of the University Leuven (Belgium), in a review lecture during the Presidential Symposium of the ESTRO conference on October 9. For example, stem cells that settle in the organ systems could be stimulated and then repair tissue damage. Radiation therapists have been following this track for some time in various projects that are presented at the ESTRO conference.


Even though the results were obtained in studies on mice, I hope that the radio-oncologists are taking note...!


INTERNATIONAL PROJECT. Rob Coppes of the University Groningen (The Netherlands) presents an EU-sponsored international undertaking at the conference, which is called the "FIRST Project" for short. (FIRST stands for "further improvement of radiotherapy through side effect reduction by stem cell transplantation").

The researchers have discovered that the side effects of a radiation therapy on various healthy tissues, such as skin and mucosa, can be reduced by treatment with adult stem cells. The stem cells migrate to the radiated tissue and support its regeneration. If studies confirm that this stem cell effect also occurs in humans, this would expand the treatment options for tumours because currently valid radiation dosage limits could be surpassed.

For instance, a radiation-biological research team led by Wolfgang Dörr of the Clinic for Radiation Therapy and Radiooncology at the Technical University Dresden reports that adult stem cells can reduce the side effects of radiation therapy on the mouth mucosa in mice. The scientists observed that the radiation tolerance of the mucosa was clearly increased if the animals received a bone marrow transplant prior to or during a fractionated radiation - during which adult stem cells are also transferred practically automatically.

A comparable effect was also observed by the scientists when they lured the stem cells from the bone marrow of the radiated animals into the blood circulation by injecting a growth factor, called G-CSF for short.


MESENCHYMAL STEM CELLS PROTECT. A team led by Dr. Michèle Martin of the Service de Génomique Fonctionnelle from Evry (France) also reports on studies in mice. The researchers had treated the animals with a radiation dose that led to tissue damage of the skin within three weeks. Without treatment, it took eight weeks until this damage had healed. Part of the mice was injected by the researchers with human mesenchymal stem cells 20 hours after the radiation exposure. The stem cells were adult stem cells from, e.g., the bone marrow that can differentiate into fat, cartilage, tendon, skin or muscle cells.

The scientists noted that the skin damage in the treated animals healed faster and better than in the untreated animals. In addition, the scientists examined tissue samples from the damaged skin areas. The stem cells - so the result - had indeed migrated to the radiated skin regions. As Martin reports, their morphology was similar to that of the epithelium.

I have a few friends who are currently undergoing chemo and radiotherapy. If eating and breathing could be made more comfortable, I'm sure they'll want to know about it. I'll tell them about it tomorrow.

No regrets about cord blood stem cell banking

Despite what any doctor may tell you about not needing your own set of stem cells (yes, there are a minority of doctors out there that still have audacity to actually advice patients against storing their stem cells!), it is also equally likely that should you be ill and need them, that you might be unable to obtain them in time for optimum treatment. This story showcases 2 families who banked their baby's stem cells when there was no apparent need to do so at the time, and used them to successfully treat their children.

The first story relates the experience of a 33 year-old father who banked his child's cord blood stem cells when his son was born in the year 2000. The family had no history of cancer, but his child developed leukemia and fortunately, since the stem cells were already banked, they were recalled quickly and managed to save his six year-old son. His advice to other parents is that this can happen to anyone despite the slim chances that most doctors and websites state and "if there's insurance against it: Buy it."

Now, almost a year after the procedure, the father can't understand why to bank or not to bank is even a question.

Quotes from the father: "I remember sitting there in the hospital thinking, what if we had never done that? What if we hadn't stored the cells?" he said. "Was it an act of God or fate that had our family doctor mention that one line about cord blood a few years ago? It's changed our lives, for sure."



The second story relates to Lisa Farquharson whose son Jesse was diagnosed with a rare form of eye cancer known as Retinoblastoma in 2001 and used his own cord blood stem cells as part of his recovery post chemotherapy.

Quotes from the mother: "We are the odds maker," Farquharson said. "We had no medical history. We were the family that should never have (banked). We proved the critics wrong."

"How guilty would we feel if we passed it up?" Farquharson said, noting she's felt the anguish of parents of ill children who didn't have the option to bank.

"We tell everyone they should do this. It saved our son's life. It's like spending money on a lottery ticket. But if you never use your child's stem cells, you win the lottery."


StemLife has enabled 2 successful cord blood stem cell transplants in Malaysia to-date and aims to make cord blood stem cell banking services affordable and accessible to all expecting parents.
Our StemLife family members bank their children's cord blood stem cell units hoping never to have to use them but in the knowledge that the stem cells have been placed in the care of good hands and are available for use whenever they are needed. :)

If you have a twin brother, he can donate his adult stem cells to you

I was reading some of the news that's published on the web (my usual after-dark activity) and came across this very interesting account of a journalist whose brother was diagnosed with multiple myeloma and was called upon to donate his stem cells. It really is rather well documented and very emotional description of what his feelings for his brother, the process that he went through for stem cell harvesting and also the potential huge amounts that would have been spent had he not been able to donate.

Having read his story, I think that the doctors should have banked some of his own for him -whilst he is healthy- just in case he also develops the cancer and requires his own stem cells for a transplant. I've copied the story here in full text, just in case the link goes off-line, and I've also added in my own thoughts in italics just to share with you the experiences we've had at StemLife.

THE STORY:

My brother, Gene Berthelsen, was born at 5:13 p.m. on Oct. 4, 1937. I was born 20 minutes later at 5:33, although it could have been the other way round. We're not sure.

That's because when our mother brought us home from what was then Siskiyou County Hospital in Yreka, and bathed us for the first time, she took the hospital-supplied identification bracelets off both of us. Once finished, she told us decades later, she discovered we were so identical that she couldn't figure out which was which. One of us arbitrarily became Gene and the other John, which was disconcerting. Even though we were separated only by minutes, over the years, as we grew up in the remote mountain town of Etna, near the Oregon border, we developed an older brother-younger brother relationship -- he steadier and more responsible, I more rebellious and immature; he has lived his life in California, I have spent much of mine in Asia. He is also one of Northern California's most prominent traditional jazz musicians. I play CDs on the stereo.

We are monozygotic, or mirror twins. I am left-handed, he is right-handed, a sign that we originated from the same ovum. Because we have suffered almost exactly the same diseases at nearly identical times, when he was stricken with bone marrow cancer last year I was filled with dread. The multiple myeloma he contracted became a foe we both would fight. Our remarkable similarity, we hope, appears to be a key to prolonging my brother's life. This is a story of our unique advantage in battling cancer and the very real danger that what happens to one could happen to the other. Since I live on one side of the planet, he on the other, the fact that we share the same DNA has brought us into more intimate contact with each other than we have known for decades.

In the face of vastly differing diets, climates and lifestyles, our body weight has usually been within a pound of each other. Despite the fact that our careers have separated us by a third of the globe, we remained largely identical for many years -- enough so that once, rounding a corner and unexpectedly encountering a full-length mirror, he asked it what I was doing there. Even after we broke our noses in separate childhood accidents, his curved slightly to the right, mine slightly to the left, maintaining the mirror image. On meeting us together for the first time, his oncologist, Dr. Ginna G. Laport, did a double-take and asked which of us was which, despite the fact that at that point he had lost most of his hair and I am bearded.

In February, I flew from Hong Kong, where I live, to the United States to donate adult stem cells to be injected into him in an attempt to restart his bone marrow production and re-create my immune system in his body. Interestingly, it is also expected to give him any allergies I might have acquired over the years. Thus, whatever physical divergences we have undergone over almost seven decades and wide geographic separation are about to end. We are about to become one again.

The story began on May 27, 2005 when, after complaining for several weeks of what he thought was a severe charley horse, my brother received a chilling diagnosis, multiple myeloma, or cancer of the plasma cells. As the cancer grows, it tends to clump up within the marrow and eat away the bone. He required the immediate insertion of a titanium rod in his left femur within hours. If the operation hadn't taken place, his doctors said, the bone could have disintegrated in an instant simply from walking. Later, cancer also would be discovered in the marrow of his pelvis and rib.

Until fairly recently, a diagnosis of multiple myeloma was almost a death sentence. Even today the survival rate is only three to four years, according to the American Society of Hematology. That was enough to send my own blood racing, not only out of concern for my lifelong doppelganger, but because our medical histories are so similar. In 2002, for instance, when I entered the hospital for a triple bypass operation to clear blocked arteries, he was operated on just three weeks later for the same problem. Could cancer be an inevitable part of my future?

Indeed a very valid question and at StemLife, we provide banking services to enable healthy adult donors to bank their own stem cells for a potential future need, alleviating the daunting prospects of having to hunt for a donor.

Dr. Laport, an oncologist at Stanford University Medical Center Bone Marrow Transplantation Program, says nobody really knows today how much of a role genetics plays. Certainly there is an obvious genetic predisposition among siblings, especially among those who share identical DNA. But, Laport said, unidentified environmental factors play an equally vital role -- or played, probably 20 to 30 years ago -- an irony for us, as my brother spent his life in the relatively clean surroundings of Northern California, while I have spent much of the last three decades in several environmentally degraded Asian countries.

DTR a fellow blogger is extremely concerned about HK's continually degrading environment, check out his blog on this here.

Fortunately, my brother is a member of Kaiser Permanente, one of the biggest health maintenance insurance plans in the United States. Despite controversies over limitations of care to some patients in other areas, Kaiser was willing to pour vast and expensive resources into his care.

For several months, Kaiser doctors sought to control his cancer through chemotherapy, with mixed results. Then, in December, they were elated to discover that he had a twin brother whose DNA was identical. Unfortunately, that brother was 7,000 miles away. Exhaustive physical examinations ensued in Hong Kong, including the drawing of 12 vials of blood to test for such afflictions as AIDS, syphilis and others. I emerged clean and ready for California.

Until relatively recently, close siblings and those who shared identical DNA underwent bone marrow transplants rather than stem cell transplants. Fortunately, that is no longer necessary. Bone marrow donations are excruciatingly painful. The donor is anesthetized while holes are drilled in the back of the pelvic saddle for the extraction of marrow. That pain has largely been eliminated through the substitution of transplanted stem cells for bone marrow.

Bone marrow extraction is quite painful (sometime excruciatingly so) and involved a surgical procedure which can be traumatic to a child or an adult. This procedure is now quite unpopular and many donors have turned down donating their stem cells due to the pain and risks involved. Those who donate their marrow once, very rarely will undergo the procedure a second time.

The common misperception is that stem cells are found only in the nuclei of human ova. The stem cells found in the human ovum are embryonic stem cells, which are even more immature and less differentiated than hematopoietic stem cells, which promote the formation of blood cells. Hematopoetic stem cells are found in the bone marrow of all humans. Over the past 15 years, doctors have discovered that they can increase the production of immature hematopoietic cells by the injection of a hormone called granulocyte colony stimulating factor, known commercially as Neupogen.

If no independent donor can be found, cancer patients donate their own stem cells, which can be manipulated and processed to remove cancer cells, and then transplanted back into the patient. But, according to Adele Ullner, a Stanford Blood and Bone Marrow Center nurse, it is difficult to remove all cancer cells from a stricken patient's cells. Having an independent donor with identical -- but cancer-free DNA -- is far preferable and gives the patient a far better chance for longer remission.

They also have a relatively cheap donor. Finding an independent donor with similar DNA costs about $300,000, about triple the cost of that from an identical twin. The cost for the remainder of his oncological care, including the removal and replacement of his femur, probably ran to another $100,000. Our medical situation is certainly unusual, although we are not particularly rare, since about four of each 1,000 live births result in identical twins, a pattern that seems to have held steady across different ethnic groups for ages. Stanford's cancer program, Ullner said, has been doing marrow transplants for 16 years. To her knowledge, this is the first time an identical twin has been found as a donor.

Neupogen injections to stimulate stem cell production are no picnic. Although often they involve little pain, at odd times they involve pain so acute, Ullner said, that some receiving the shots call the hospital in the belief that they are having heart attacks.

These pains strike at odd times. For me, I was lying in bed watching television. I got up momentarily to discover that every single heartbeat was sending what seemed to be a pulsating electric shock through my body. I was reminded of a time when I was a child on our father's dairy farm and on a dare I touched an electrified cow fence. Painkillers such as Vicodin help, but there are times when even Vicodin doesn't slow those electric shocks. Another possible side effect is an enlarged spleen. (Indeed, those injected with Neupogen are warned not to fly for at least three days after the process because one patient who didn't wait suffered a ruptured spleen while in the air. The 14 1/2-hour flight back to Hong Kong was no place to experiment.)

I wonder what dose of Neupogen was administered, StemLife clients who have been stimulated do not always experience any side effects- perhaps it is because we use a lighter dose.

At the end of the five days comes "apheresis,'' the harvesting of those stimulated cells. It is mainly boring -- sitting in what vaguely resembles a dentist's chair, a tube in the left arm draining off blood, which then runs through a centrifuge that separates out blood stem cells before the remainder of the blood is returned through the right wrist. About 9 ounces of blood is outside one's body at any given time. The blood is chilled before being returned, which for some odd reason makes your nose itch. Over about four hours, the 4,750 cubic centimeters of blood in my body circulated through the centrifuge more than three times, passing 15,045 cubic centimeters through the machine to produce what my brother needed.

The process does indeed take up an afternoon, we usually recommend that donors bring their own DVD's or select from our wide range of entertainment ranging from a 2 hour foot reflexology, amusing conversations with our team members or music to make the time go by effortlessly. All whilst in the care of a very professional team.

I was surprised to discover how much the process had weakened me. On my first trip back to the elliptical trainer, where I usually exercise for an hour, I lasted only 15 minutes before staggering off. It would be weeks back in Hong Kong before I found myself fully recovered.

Interesting, on the contrary, our stem cell bankers return to normal work the very next day. Perhaps it is age? The author is 69 years old. However, our eldest donor is a very jolly 88 year old gentleman who didn't report any exceptional tiredness or side-effects..!

The Stanford Blood and Bone Marrow Center itself, where the procedure took place, is a remarkable institution, seemingly paying as much attention to patients' emotional and spiritual needs as their physical ones. Patients are provided with voluminous information about their afflictions, with complete descriptions of the emotional issues they face both prior to and after recovery, of sadness and depression two to three months after the transplant is completed. Extensive counseling services are provided both to recipients and donors. Gene's doctors at the facility set out to destroy the cancer cells in his bone marrow, and along with it the entire marrow itself, as well as his immune system. In the early years of the program, cancer patients were sequestered in sterile rooms for 100 days, because any contact with any kind of virus would kill them, before regenerated bone marrow cells were injected back into their bodies.

That, thankfully, is no longer necessary. Huge doses of antibiotics allow patients to live relatively normal lives, although they must wear inhalators when outside.

Nonetheless, it is a horrific process. For months, he underwent chemotherapy that cost him his hair and much of his vitality. He was required to drink three liters of water a day to flush out his liver and kidneys. If he didn't, the chemicals could destroy his vital organs.

Then, starting on March 15, the process of destroying the cancer cells accelerated drastically when a cocktail of virulent drugs was injected through a catheter in the center of his chest. The drug also delivered immediate side effects including nausea, vomiting, decreased appetite, diarrhea, fatigue, sores in the mouth and throat, and decreased blood cell counts. Later possible side effects could include sterility, cataracts, hypothyroidism, scarring of the lungs and second malignancies.

High-dose therapy, as it is known, kills all cells that form newly reproducing elements of the body -- not only bone marrow but hair, fingernails, semen, saliva and blood cells that reproduce to fight disease. It results in infertility because of the permanent damage to sperm cells in men and ova in women. In other words, the medical process comes as close as possible to killing the patient in an effort to eradicate the cancer cells.

On March 23, the process continued with the transplant of my DNA into my brother's body to seek to re-create his bone marrow and immune system. The toxicity of the chemotherapy was now so high that he required the constant injection of fluid through a catheter to keep the poisons from destroying his vital organs.

Would he make it? In the cold language of the disclosure statement of the Stanford University medical consent form, if both my DNA and the cells he donated as a backup failed to grow, "then this complication would be expected to result in death."

He ultimately grew so ill that the Stanford doctors became concerned that his body was rejecting my cells. He lost 26 pounds in two weeks, or nearly 15 percent of his body weight. But finally, on April 7, after virtually nonstop vomiting and diarrhea, his white blood cell count started to rise. "Engraftment,'' as his doctors called it, had begun. My cells had been transplanted, prompting a weak joke from him that he had suddenly become left-handed, as I am.

On April 21, he was finally able to return to his Sacramento home, weak, debilitated and raspy-voiced but on the mend. Along with everything else, the chemotherapy had destroyed his ability to produce saliva, making him sound like he had aged 20 years in a matter of weeks. He said he looked more like Uncle Fester of the Munsters than Yul Brynner.

Now, however, he is recovering his old vitality -- along with his hair, which oddly is coming back in different colors. He has regained 13 pounds, although he has continuing neuropathy -- numbness in his hands and feet -- and he is dizzy when he stands too quickly. But tests in mid-July showed that levels of IG (g) protein, an indication of his kidney function in battling myeloma, had fallen to healthy levels, meaning he is now cancer-free.

Ultimately, the process, according to Laport, should dramatically extend his time in remission, at which time other therapies should come into play.

On Sunday, April 30, two weeks after the final process was completed, Gene was able to return to the musical stage at a jazz festival in Jackson, pick up his cornet and front the Catsnjammer Jazz Band, as they have been called for nearly 30 years. He didn't play long, but he played. After all, in the 1920s, jazz cornetist Joe "King" Oliver wrote this song:

Hello central, give me doctor jazz

He's got the thing for me, I'll say he has

So when I'm in trouble and when I've got the blues

He's one who makes me put on both my dancin' shoes.


You saved your brother with your adult stem cells. Thank you for sharing your story. It is so important that more people understand the process of stem cell collection and use in cancer treatment and to know that it really isn't hocus-pocus or useless. Perhaps you might like to come bank your own here with us in KL!

Cancer transplants: Bone Marrow and PBSC Q and A's

Bone marrow transplants are often performed for cancer (esp. blood cancers) and usually offered only at major oncology centers. Here in Malaysia, bone marrow transplants are performed for cancer patients and also for other blood disorders like thalassemia major and other severe anemias.

I was reading the National Cancer Institute's website which I thought had a rather informative Q and A section explaining the different types of transplants with stem cells from sources obtained from bone marrow and peripheral blood stem cells (PBSC).

It also mentions donation of cord blood being free of charge, but it does not mention how much it will cost to acquire the stem cells from any of the sources, merely that aspects of it may be covered by insurance.

Do have a read if you'd like to know more about bone marrow transplantation and understand the different types of transplants that a cancer patient may undergo.

First Collective Interview of Adult Stem Cell Patients with Successful Outcomes

I read with great interest an announcement that a few successful adult stem cell therapy patients would be gathering in Washington to share their experiences and show how they have improved.

Many patients are tremendously shy when discussing their condition and I think its marvellous that they are willing to come forward. No doubt there may be a political slant to organizing this event (given that Senator Sam Brownback from Kansas and Dr. David Weldon who is from the House of Representatives will be giving keynote speeches), but if it is to promote awareness and funding for stem cell clinical trials and to further understanding of applications, I'm all for it.

There were 5 featured speakers:

Jacki Rabon- Stem cells used for treatment in her spinal cord (see previous entry)

Cathy Pell- Daughter Abby received cord blood treatment for cerebral palsy and used her own cord blood stem cells

Dr. David Foege- Heart failure patient who underwent Theravitae's stem cell therapy developed by Dr. Amit Patel in Pittsburgh

Mary Schneider- Son Ryan treated with his own cord blood when he was 2 for cerebral palsy at Duke University (same as Abby)

Stephen Sprague- Was diagnosed with CML 10 years ago and used cord blood stem cells for a transplant source and is well today

Apparently they shared phenomenal stories of success in their treatments and encourage more adult stem cell work to be done.

"To date, embryonic stem-cell research has failed to produce one successful treatment," said Paul Chaim Schenck, director of the national pro-life action center. "Conversely, adult and cord-blood stem-cell research has yielded over 65 successful treatments, including curing diabetes in some patients."

Interestingly, the session was organized rather innovatively as a wine-tasting session sponsored by a company called BOGO wines. Its owner, Bill Schneeberger is a Catholic from Ohio who donates $2 (USD) from every bottle sold to adult stem cell research. Check out the follow-up article here, it's got some interesting insights to the event but not much on the patients themselves.

I would have loved to be there to listen and ask them questions. If anyone reading this blog attended the session, I'd really appreciate if you'd share the information with me.

Breast Reconstruction with Stem Cells from Fat


An interesting report yesterday on stem cells obtained from fat tissue for breast reconstruction for women who have undergone breast cancer surgery.

20 women who have undergone partial mastectomies for breast cancer are enrolling into a safety trial at Kyushu Central Hospital in Fukuoka, Japan. The research team is led by Dr. Keizo Sugimachi (the president of the hospital) and already 3 women have had a procedure similar to liposuction. The fatty cells are put through a machine known as the "Celution System" developed by Cytori Therapeutics (I suppose they would be sponsoring this trial), where the stem cells are concentrated in an hour, and sent back to the surgeon for injection into the affected breast. It will only be known after 6 months if the patient will know whether the stem cells implanted will be able to replace the lost tissue.

Currently, this is a safety trial and tests the machine manufactured by Cytori, and will indicate the quality and quantity of the cells at output. Cytori will then probably submit the results for their CE European approvals and the FDA approvals for subsequent marketing in the US.

I met a scientist from Cytori Therapeutics at a stem cell conference I attended last year in Pittsburgh, he shared with me that this machine has been years in the making with much money invested to optimize it for on-site use. You might like to know that Cytori used to be known as StemSource, a company founded by a well-known plastic surgeon based on the west coast of the US.

I wonder how much fat one has to be able to contribute, what volume the cells will be returned in and how they can be implanted, the answer may vary largely from patient to patient. The selection is probably currently limited to only those who have lost small amounts of tissue (but is very unsightly) and where the stem cells will be able to stimulate tissue regeneration within an already defined site. Women who have had whole mastectomies might not be suitable candidates, unless a scaffold accompanies the stem cells to provide the right shape.

Breast mastectomies can be very traumatic, I had the opportunity to meet a breast cancer patient when I did an internship at a hospital in London (many, many years ago before StemLife) and she was kind enough to share with me her experience and show me her double mastectomy scars. It reminded me of scars from heart bypass surgery, the scar running like an uneven zip starting near her collarbone and ending at her stomach, held by steel staples. It was deforming, uncomfortably tight at times and required her to wear turtlenecks and jackets to conceal her chest (or rather the lack of it).

More than the physical discomfort or appearance, it was the psychological trauma of making the decision to have to lose both breasts. Breasts aren't like hands or feet but I do believe that feel, function and form are important to humans and the feeling of "completeness" and reflection of health to others.

Surgical techniques have improved since then of course, but nonetheless if stem cells can help rebuild tissue, heal scars and surgical wounds, the return of normal appearance may help the patient to forget the trauma of disease and get back into exercising (swimming, running etc.) and confidently move on with their lives.


Attention Kylie Minogue fans, she has announced that she's had her breast surgery and chemotherapy and ready to get back on stage to perform.


As for Malaysian, Thai, Indonesian and Singaporean readers looking for a gravity-defying Dolly Parton asset or an Angelina Jolie pout, well... that I'll save for another blog entry. :)

Cord Blood Stem Cell Transplant for 61 year-old Patient

A 61 year-old gentleman by the name of Arthur Lee who was diagnosed with Acute Myelogenous Leukemia (AML) in February this year was reported to have undergone a cord blood stem cell transplant to rebuild his blood and immune system after chemotherapy. The doctors tried to find a living donor but were unsuccessful and instead found a matching unit of cord blood. It is the first cord blood stem cell transplant for the Methodist University Hospital in Memphis, Tennessee.

Lung stem cells for Hong Kong Citizens

I'm in Hong Kong for a short trip and although there has been a typhoon that just passed by and a huge rain that whipped up as a result, the smog is back in full force. It remained hazy and cloudy all day long, not entirely in a cumulonimbus-rainy sort of way, but that which reminded me of forest fires plumes drifting above the Petronas twin towers during the Sumateran forest fires.

A question posed to me this evening was if stem cells might help replace cells affected by pollution and perhaps that this regeneration might help desist lung cancer?

I know that Helen Rippon is working on deriving lung cells from stem cells to coat an artifical lung but I guess it isn't quite the same. No answer from stem cells yet, so better just to sort out the roots of the pollution. The costs to government, healthcare facilities and citizens might work out to be just the same.

35 year-old Adult Peripheral Stem Cell Donor for Cancer Patient

This is a nice write up on a peripheral stem cell donation and procedure of transplant for a lady (Susan Butcher) with leukemia. It doesn't mention however, how many stem cells she requires from her donor and whether its the donor's first time. Notably though, the donor is young and the stem cells that the patient is receiving are healthy and hopefully will reconstitute her blood system in 2 weeks. Another more detailed article describing her chemotherapy and radiotherapy can be found here.

Stem Cells Extend Life for Cancer Patient

Check out this nice blog entry by a columnist in the US, Rick Badie. He describes a golfer, Jim Gates who finds out that he has multiple myeloma* and has undergone his own stem cell harvesting (peripheral blood stem cells) at Emory University Hospital and the procedure has helped extend his life for an estimate of 2-6 years. At least this will give him enough time to set his affairs in order and spend precious time with his loved ones, which the most of us often take for granted.

It will be interesting to know if he can undergo a second round of transplantation to extend his life further. Mr. Badie, please keep us informed.

Another interesting stem cell transplant story for Multiple Myeloma where the patient, Brian MacLeod complemented his treatment with a medical combination of east and west, blending chinese acupuncture with herbal remedies. The transplant took place in the year 2000 and he's still fine 6 years after.


*Peripheral Blood Stem Cells Harvesting for Multiple Myeloma is well tolerated in elderly patients of 60 years old and older. A recent study at Mayo Clinic showed that mobilization (where stem cells are generated from the bone marrow into the bloodstream) was successful in 95% of the patients and that statistically there was no difference in treatment outcomes of elderly patients or younger patients with this technique.

It was concluded that elderly patients with intermediate-stage Non Hodgkins Lymphoma or Multiple Myeloma derive benefit from autologous stem cell transplantation, particularly those with a good prognosis.

Reports of Stem Cell Transplant for treatment in Hurler Syndrome and Leukemia

Two patient cases reported recently needing stem cell transplants to treat their condition.

The first story is about a 1 year old boy Justin Wolford with Hurler syndrome who gets an 8 hour weekly enzyme replacement injections at Hershey Medical Centre. However, the enzyme injection is only temporary and the only way to slow the progression of the disease (85% chance of stopping) is a stem cell transplant. Hurler syndrome (otherwise known as muccopolysaccharidosis Type 1) is debilitating on the growth of children and are progressively neurologically impaired with a possibility of early death. Gone undetected, he could have been faced with a life of progressing mental retardation, hearing loss, clouding of the eyes and spinal deformities. Eventually, the mother said, his organs would have begun to shut down.

Unfortunately, his only 7 year old sister was not a match and a matching unit is in the process of being found.

Malaysia has a number of Hurler syndrome sufferers (US estimates of incidence is 1 in 25,000 but I couldn't find any numbers for Malaysia) and I wonder if they are aware that with an early diagnosis and stem cell transplant, their child might have a decent chance of living quite normally. StemLife did have one enquiry for this condition, but the child was already of significant age and there was a significant risk associated with the procedure.

The next story is about an 8 year old boy, Zachary McCracken, who has been fighting acute lymphoblastic leukemia for three years but relapsed and received an umbilical cord blood stem cell transplant last week. Three months ago, the McCrackens were hoping to find a bone marrow match for the boy. Hundreds of the boy's neighbours donated blood during a December fund drive at the boy's school, but the family was unable to find the right match. They had little choice but to search for a suitable unit of cord blood, but the article does not specifiy where they obtained the unit. The transplant was conducted at Duke University Hospital and the parents will wait out the 4-6 months until their son is able to leave the isolation room.

Zachary McCracken and his recovery is available online. Fingers crossed for both these young patients. The StemLife team hopes they are able to return home soon.
