Thread: The Shady Side of Embryonic Stem Cell Therapy

    The Shady Side of Embryonic Stem Cell Therapy

    This is a very good article by Stephen Barrett, M.D. about "embryonic stem cell therapies" that various clinics and doctors are offering around the world.

    The Shady Side of Embryonic Stem Cell Therapy

    Stephen Barrett, M.D.

    Stem cell therapy is certainly a promising area for research. Stem cells have the ability to give rise to many specialized cells in an organism. Certain types of stem cells are already used to restore blood-forming and immune system function after high-dose chemotherapy for some types of cancer, and several other restorative uses have been demonstrated. The broadest potential application is the generation of cells and tissues that could be used to repair or replace damaged organs. If scientists can learn how to control stem cell conversion into new, functionally mature cells, doctors might be able to cure many diseases for which therapy is currently inadequate [1,2]. However, the claims made by commercial promoters go way beyond what is likely and should be regarded with extreme skepticism. The main commercial sources appear to be Embryonic Tissues Center in the Ukraine, and Medra, Inc., in the Dominican Republic....
    Embryonic Tissue Center (EmCell). Barrett pointed out that EmCell did not answer many of the questions and concluded that "We have not found any data that suggests that the methodology used by EmCelll is scientifically reasonable, or that it is helping ALS patients..." It points out that EmCell suggested that "the number of cells does not matter since the cells will divide once they are in the body" and that "these stem cells DO NOT draw the attention of the immune system...", saying that both of these are red glags that suggest that Emcell does not understand how stem cells work and does not comport with known information about immune reaction to stem cell transplants.

    Embryonic stem cell transplants. Please note that they are probably referring fetal stem cell transplants and not embyronic stem cell transplants derived from blastocysts. The article reviews Dr. William C. Rader, M.D. of Medra, the "chief American commercializer of embryonic stem cell research" in Malibu, California. For "$25,000 (wired in advance), Rader will arrange for treatment at his Dominican Republic clinic." It points out Rader also claims that "his fetal stem cell treatment is not antigenic and has no side effects." Rader also claims that the treatment is beneficial in a very large list of diseases ranging from ALS and Autism to Spinal Cord injury and Stroke.

    Cord Blood Banking. The article describes the Cord Blood Registry headquartered in San Bruno, California which charges $1,600 for processing and $100 per year for storage. It also mentions Cyrobanks International in Alamonte Springs, Florida. Barrett points out that the advertising by these organizations contradict the American Academy of Pediatrics position that there is no strong evidence supporting routine cord blood banking for future use by the infant.

    The Quackwatch Home Page has many other articles about nutrition supplements and other treatments for cancer and the like:

    In summary, Stephen Barrett points out several red flags that people should pay attention to when evaluating alternative therapies. Among these are claims that the therapy cures everything, the suggestion that it is completely safe, and the absence of peer-reviewed evidence supporting the claims (even though the service has been provided for many years). The article contains links to many excellent resources concerning stem cell therapy.


    P.S. Originally, I had posted this article in full but, in keeping with the new copyright policy of the site, I have excerpted it below and people can read the full article at the site above.

    Dr. Young:

    It was nice to communicate with you in the Chat Room and thank you for addressing the issue of "The Shady Side of Embryonic Stem Cell Therapy."

    Paul, you are of course very welcome. This is a very sober article and one that sets forth a number of criteria for judging the claims of these organizations.

    People should be suspicious when an unknown group that has no track record in doing stem cell research suddenly makes claims of cures beyond what anybody has been able to achieve.

    Fetal blood cells carry some antigens, notably the ABO groups and the one which is the most trouble, Rh. If they didn't we wouldn't need Rhogam (Rh immunoglobulin)

    When umbilical cord blood is used for therapy, one tries to match as much of the antigens (including ABO and Rh, as well as HLA antigens). It is not difficult to get ABO and Rh matching. That is what is done everyday in blood transfusion. Getting HLA (human leukocyte antigen) matching is much more difficult.

    HLA are histocompatability antigens and fall into three classes: HLA-A (>25 forms), HLA-B (>50 forms), and HLA-DR (>15 forms). If people want to read more about it, the National Marrow Donor Program has a good web site on the subject.

    Dr. Wise,

    This is very sad. Yet expected in a way.
    I almost feel terminally ill individuals look
    for those reputed as quacks.

    The string of hope is very strong..and when
    the reputable sources have no is
    relatively normal to explore other routes.

    All the news items about stem cells have many
    interested in treatments now..before their time runs out. I guess it would be ideal to
    leave it out of the press until something real is available.

    On the 9 of March 1911 the New York Times
    ran the following article:

    The Rockefeller Institute in this city believes it's search for a cure for infantile
    paralysis is about to be rewarded. Within six
    months, according to Dr. Simon Flexner, definite anouncement of a specific remedy may be expected.

    "We have already discovered how to prevent the disease," says Dr. Flexner in a statement
    published here today. "and the achievement of
    a cure, I may conservatively say, is not now far distant."

    Embellished press releases is what gives the quacks their power, yet are necessary to get
    funding...double whammy as usual.

    What you are referring to are breathless press announcements that are not primarily meant for people with spinal cord injury and disabilities. They are really aimed at venture capitalists and potential investors.

    It is the direct advertisements to people with disabilities, quacks who are trying to convince people to pay money for their unproven treatments that is a problem.

    Rader was a client of mine on and off for a number of years. Been into their West Los Angeles offices when the weight loss thing was in full swing, and later in the Malibu offices.

    In tinsle town, acadamy award winning performances abound both on and off the set. So perhaps my impression of genuine concern to help folks with innovative ideas was based upon a series of well rehearsed performances.

    admittedly intentions do not justify means....and individual motivations of the afflicted can lead to poor decisions. I suppose the upside is that nobody has died from these experimental procedures, which probably won't damage future prospects of human trials with cell therapy - this time. If somebody does die as a result of these "rogue" acts, it could seriously impede future trials - and we don't need that.

    However this does illustrate a prevelent problem in our current system: the gap between global and animal research vs clinical application of new therapies in the US. We are simply not leading the race on clinical cell therapy and people here know it. So why re-invent the wheel when it has been done? Let's just build upon it and allow patients to benefit. After all, if we can justify a multi-billion dollar war to "protect our way of life", we should be able to loosen the noose a little on health care research.

    As we know, in the absence of an approved procedure, people in certian situations will justify taking a personal risk that others may determine to be foolhardy. It's a personal decision - often driven by pain and frustration. Without a santioned option, these "motivated" people will seek unsantioned options, exposing them to potentially dangerous situations.

    I believe we need an environment(process) that will let individuals with certian life altering afflictions (cancer, SCI, etc) undertake experimental procedures - under the right conditions. ie substantially less stringent than the "normal" FDA approval process, yet with enough common sense safeguards to prevent overtly dangerous procedures.

    For instance, if overseas human or domestic animal trials have been successful, a methodology to expedite human clinical testing for individuals that are willing to accept the associated risks of a new therapy.

    In short, we need more open pre-trial critera for clinical research, specifically for people with major afflictions.

    The upside is too great to ignore - better documentation and understanding of overseas based techniques, reduced R&D costs, faster turnaround from lab to clinic, access to lots of willing patients, and most importantly - a sanctioned outlet for individuals with major afflictions that is sane.

    Until that happens, we are at risk of people "jumping the gun" and trying things in a totally uncontrolled manner, with consequences that could damage the future of a viable therapy.

    As a motivation for govt. to implement such a system, perhaps if we build a database of individuals with major afflictions, and use their collective barganing power to gain attention to implement qualified pre-trial testing, we might be able to effect a far reaching process that will ultimately benefit both science and citizens.

    I just happen to already have an IT infrastructure (database etc) ready to go... just needs names and some input for the bill (mostly liability restrictions) to be introduced... anybody interested?

    sorry if I may have hijacked the topic, but it's seemed relevent at the time.

    Your post has to be one of the best I've

    I would think your database would become
    overfull if presented to the various groups

    It is very hard to discern if the two doctors
    involved are "rogues" or "quacks".

    The ALS watch people seem to be the ones most
    involved..yet on EmCells mention
    of ALS that I could find.

    Best of luck with your database project..
    The very best of luck.

    Dr. Young-
    For starters you are a true pioneer! Without you SCI research would NEVER be where it is today. You have been of incalcuable help and support. Thank you for each and every letter you've written me and all else back. At this rate you must have serious doubts about therapies to restore substantial function in the next several years. Being a man of science, the science hasn't translated out of the lab and into concrete results. Please feel free to disprove me at any time. You cannot rationally believe that paraplegics' who've been injured for years will walk again. With stem cell therapy approved for study in New Jersey, how long do you think it would take to get concrete results if the science actually worked?
