'Plentiful' Non-Embryonic Stem Cells Found 489

Posted by Zonk from the bumper-crop dept.
An anonymous reader writes "CNN reports that scientists at Harvard and Wake Forest have discovered a 'plentiful' non-embryonic source for stem cells, as well brain, liver, and bone cell types as well. The cells, found in amniotic fluid, can be harvested without harm to the donor or the donor's unborn child. While there's no proof that amniotic stem cells are as potent as embryonic stem cells, scientists are hopeful that this will be a huge step forward for the field of stem-cell research."

    From what I can gather, the basic issue that most religious folk have to do with stem cell research is that we're mucking around with human lives. Unless you can make this process look as simple as a cheek scraping for human cells (allergy research, for instance) the objections will not abate.

    The argument that this cell couldn't have become a baby doesn't quite hold good and has been answered before [slashdot.org] about harvesting eggs from fertility clinics.

    So are these cells are still human, but without a potential human, doomed to die when the aminotic fluid drains. Some facts which might not matter to those who have decided all of this to be Playing God.

      It's a good point -- to the public it's all about the perception of the science, not the actual science. I suspect lots of people will see "stem cell" and react immediately. Hopefully lots of other people will be more reasonable.

      I don't think there's any way to make it look as harmless as a cheek scraping, though -- from my meagre understanding, there's still a risk involved with going into the amniotic sack - any medics able to comment further?

      The objection is not that embryos are potentially people, is that they are people. This is not true about some cells harvested in such a way that it does not destroy a person (whether embryonic or adult).

      Whether you agree with the classification of embryos as people is what the debate should be about. See http://www.gerv.net/writings/foetal-personhood/ [gerv.net] for some pointers
    • I'm sorry, but the idea that embryonic stem cells could have become a baby is precisely the objection that most of the people who object to ESC research have. That someone figured out that embryos aren't humans on a Slashdot discussion is of no concern to faith-based folks like George W. Amniotic stem cells can't become a baby, so no one cares. Amniocentecis isn't quite as easy as scraping a cheek, but it's probably as close as we're likely to get with stem cells.

        I'm sorry, but the idea that embryonic stem cells could have become a baby is precisely the objection that most of the people who object to ESC research have.

        I'm afraid I have to disagree here. The problem is not with stem cell research, or even the fact that it is possible to manipulate a stem cell into becoming a human being, but how you got the cell in the first place.

        I fully support stem cell research. I think it is a sin not to. The only problem people like me have with embryonic stem cell research is not the research at all, but the production of the stem cells to begin with. In order to harvest embryonic stem cells (as my feeble mind understands it), an embryo must be coaxed to divide and start to grow. At a certain point, it has to be destroyed to harvest the stem cells. It's that destruction of a growing embryo that is the problem. People like me equate that to an abortion, but it's no longer about women's choice, but experimentation and profit.

        Now we can get into a ton of philosophical debates as to when life begins and when an embryo becomes human and such, but this debate goes into so many different directions. If we agree not to harvest embryos for stem cells because they are human, then they must be human when considering an abortion. If an embryo is not human, then why the rub about abortion? This is another reason why the debate gets so heated. There is more at stake than just stem cells.

        Most people want embryonic stem cells for one or a combination of three reasons:
        1) Bush said not to and it pisses off fundies (these tend to go together)
        2) It legally reaffirms that embryos are not human, and thus abortion remains legal
        3) They want to stop the suffering humans with diseases that stem cell research promises to cure, and they don't know that stem cells can come from other sources.

        This is why other sources must be found. It's not because anyone is right or wrong, but because neither side will ever give up. Will it get to the point where fundies are blowing up research labs and feminists are performing stem cell harvesting with coat hangers? Doubtful, but why have the debate at all when there are other means of harvesting stem cells than to kill a growing embryo? We really can have our cake and eat it too!

      You're wrong on two counts. 1) The primary concern was that extracting the stem cells would destroy the embryo, not "Playing God". 2) You're also wrong to use the "religious folk" label.

    • Would you allow your pregnant daughter to go through this procedure of donating amniotic fluid? Absolutely, if she wants to (because she's the person who should be doing the deciding, anyway). Amniocentecis is a routine procedure, a friend of mine had one done just the other week. The OB/GYN department likely performs several every day. Besides, it's unlikely that it'll do her any good after she gives birth anyway, it'll probably just be soaked up and tossed in the medical waste bin.

      If women are already undergoing amniocentesis [netdoctor.co.uk], then the risk has already been taken, so why not get extra value from the resulting fluid ?

      I don't think anyone is suggesting that the fluid is harvested on industrial scales.

    Even if these new stem cells aren't as useful as embryonic stem cells you can be sure that right wing zealots will argue that they are. I just don't get the case against embryonic stem cell research provided that research is carried out on embryos that have been donated with informed consent and would otherwise be destroyed. I could sort of understand the argument if these embryos were going to be implanted and had a real chance to become a baby, but we're talking about embryos that are going to be destroyed. IMHO destroying embryos that could be used in research to try and cure a number of truly horrible diseases is the immoral course of action.

Not only is the procedure extremely painful, she went through two weeks of uterine cramping. She had to take two weeks off work to recover.

    When I was pregnant with my daughter, I knew from the start I wanted to donate the umbilical stem cells. It wasn't an easy search to find somewhere that would take them. All the advertising toward pregnant women are for banking the stem cells. They scare parents into thinking their child's stem cells could be used for a cure on the chance the child develops a disease. I think this is a horrible practice to do on parents, most of whom probably are just throwing their money away in the belief it could save their child.

    None of the hospitals in my state accept cord blood donations, nor are their any cord or blood banks here. I found only one cord bank that accepts donations from out of state (their name escapes me), and at no charge to my doctor, the hospital, or me. From what I've read, I know that the cord blood stem cells aren't able to be used like embryonic stem cells, but since they were just going to be destroyed anyway, why not donate them?
