FDA Approves First Brain Stem Cell Transplant 245

Posted by Zonk from the hope-it-works dept.
no reason to be here writes "An article at CNN.com is reporting on the FDA granting approval to the first ever transplant of fetal stem cells into human brains. The stem cells will be transplanted into six children suffering from Batten disease, a rare, always fatal, genetic neurological illness, which renders its victims blind and speechless before finally paralyzing them and killing them." From the article: "The stem cells to be transplanted in the brain aren't human embryonic stem cells, which are derived from days-old embryos. Instead, the cells are immature neural cells that are destined to turn into the mature cells that makeup a fully formed brain. Parkinson's disease patients and stroke victims have received transplants of fully formed brain cells before, but the malleable brain cells involved here have never before been implanted."

      It is an interesting therapeutic strategy to inject stem cells foreign to the suffering patient to alleviate the problems with the patient's own DNA. The cause of Batten Disease is a series of mutations in membrane transporters with unknown function. While the mutations affect all body tissues, it is powerfully destructive to neurons and so there is the typical accumulation of autofluorescent pigments (the so-called ceroid lipofuscinosis neuronal).

      I think the most important lesson here is that injection of stem cells and the differentiation of those cells and eventual incorporation into the functional neural network is astounding. However, the limits of the therapy are quite evident, since the patient's entire brain suffers from the accumulation of lipofuscin. You'd have to inject enough stem cells to regenerate an entire brain, which is on the scale of billions (could be off by a few factors of ten though....).

      As for the cellular and genetic basis for the accumulation of pigments, I'll have to get back to you on that when I conclude my research. :-)
      • So, if healthy stem cells aren't enough to battle the disease, perhaps gene therapy might do the trick? i.e. using some kind of virus that will mutate back the cells into normal?
      • So, any prospect of a genetic test that can be done in utero before, say, 10-12 weeks gestation? I gather you're not talking a SNP, more's the pity, but a good genetic test would be a God-send. It's hideous to abort your 3-month-old fetus, but nothing compared to watching your little boy or girl die.
        • Yes, it should be fairly easy to do a genetic test of the spectrum of ceroid lipofuscinosis related genes by simply extracting DNA from any cell and amplifying the sequence and then sequencing those genes to find the mutation.

    Aside from ripping the first four paragraphs verbatim, it says ITFA:

    "What's more, some of the brain cells to be implanted will be derived from aborted fetuses, which Caplan also said raised ethical concerns for some."

    so the whole misdirection of not being embrionic is "technical" in nature for the right-to-life crowd.

    Anyway, it all seems academic until you read the bit at the bottom about the fellow who is going to enroll his 5 year old son, in hopes of not having to see his child die a horrible, slow death right in front of his eyes, with nothing he can do to save him. I think you have to be a parent to understand the enormity of the situation - I know for a fact that before I had a child, I wouldn't have experienced that "oh, my god" sinking feeling when reading his comments. I hope it works, and I fear that it works.

    Why do I fear that it works? Politics. If it works, there will be a "cure" for this horrible affliction. And it will likely require stem cells from pre-term fetuses, at least initially. If there's only one thing I can think of that's worse that seeing your child die slowly and painfully in front of you while you can't do anything to help, it would be having your child die slowly and painfully in front of you, knowing that there is a cure and not being able to get the cure. The fact that it would be the "religious" right that would block you from saving your own child is just and extra bone to try and swallow.

    I'm probably going to get flamed straight to Hell by the hardcore left fanatics but I'm still posting. Unpopular opinion is still protected by the first amendment.

    When I read this my stomach essentially sank. Anyone who thinks this is absolute right vs absolute wrong doesn't know what they're talking about.

    What the moral issue here is, is that it's essentially harvesting of human life. A human fetus is essentially a human child that has developed to the point of posessing organs, human shape and a brain. Essentially a viable human life at this point. In fact this leads to partial birth abortion in a way.

    You see partial birth abortion is essentially using a probe to kill a human fetus in the womb then extracting it. This is done with fetuses that are viable human lives once removed, thus must be killed before removal or it is considered a living human child.

    In short this is the equivilent of killing a newborn baby with the only difference being location. That however isn't the subject of this post and I'll move on.

    The article wasn't entirely clear but I'm suposing this is more likely early term fetuses not yet viable as living once removed, however it's dangerously close.

    It is a good thing that there's a method of saving human lives, and yes it's natural for one to place one's self in the situationo f the parents of these children. However that's the case of parental instinct to choose one's own offspring over another.

    Would you honestly hesitate to kill someone else's child to save your own? This is essentially the case. Any attempts to justify things into black and white are nothing more than attempts to convince one's self. Lions will sometimes kill the offspring of other lions in order to mate with the mothers and produce their own young. It's the same underlying primal instinct behind the very heated statements before this post.

    If placed in the same situation I would probably make the natural descision to save my own young at the expense of another. However I'm not going to put myself in that position and rather should make a logical choice as a third party. As a third party without emotional attachment, and assuming we are dealing with a viable human life on the other side the two sides stand roughly equal.

    In this case the side with a parent willing to take another life in order to save their child's life, against the child with a parent looking rather to avoid becoming a parent (and obviously not considering the option of adoption, which puts infertile couples on multi year waiting lists and continues to fund america's abortion industry), yes the parent willing to take one life to save their child's when met with no oposition will succeed every time.

    Much in the way herd animals will allow their young to be chased down and killed by predators in order to save themselves, as a breeding age, healthy animal has a better chance of reproducing than a still vulnerable calf that is until it's an adult, still expendable.

    But let's look at the human side of this now. Let's forget baser animal instincts and use that intellect that sets us apart from predators and prey. If you put a logical argument of life vs life, you can't so easilly come with a right answer. You have your animal instinct that gives you a gut answer, or you have the religious right with an imposed super-ego which gives them an automatic gut answer in the oposite direction.

    If we were going strictly by Darwinism, it would be better to allow the healthy unborn child to live, while allowing the child with a genetic defficiency to die. However don't confuse me as stating that that is the morally right answer.

    In terms of human morality, which exists somewhere undefinable between our base insticts, our concious intellect, and our ingrained super-ego, there isn't a clear right answer.

    Human morality dictates that human life be valued equally. An individual with a genetic defficiency has as much right to live as a healthy individual. Even
