'Plentiful' Non-Embryonic Stem Cells Found 489
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.

The donor's unborn child? An embryo is not a child. Why do we need an "alternative" to embryonic stem cells anyway? Embryonic stem cells work perfectly well, and are usually considered more effective than non-embryonic cells.
Funny how you don't see the anti-stem-cell people protesting IVF and other fertility programmes, even though they "kill" embryos 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. People who are non-religious also found that destroying human embryo's for research purposes was a concern. People who were religious argued for the research. Using statements like "religious folk" is indicates you're relying on a stereotype and in this case in particular oversimplifies the entire debate to the point of error.

You are wrong. Ethical systems are individualized first and shared second. One's world view, whether it incorporates a religious viewpoint or not, determines one's ethics. Religion has a huge bearing on individual ethics. The challenge is to communicate and discuss those ethical values across groups of people that may have different world views.

So I think that an embryo would count as human life.
Now, as to whether it is a person is a totally different issue.

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!
Re:The idea that human life begins at conception (Score:5, Insightful)
The ethical concerns over stem-cell research are over whether the embryo is sentient, and has a soul. The first is scientific, while the second is religious in nature. We can theorise scientifically that it isn't sentient, since it has not yet developed a brain, and in the absence of evidence showing you can think without a brain we accept this as being as close to true as science get.
Whether it has a soul, however, is a different matter. Religious people can argue that it has a soul from the instant of conception. The idea, however, that something can be non-sentient but still have a soul has a number of ramifications that they don't seem to have fully grasped.

I don't know if you have heard of Aristotle's Form/Matter distinction, but basically, it is this. Matter is the stuff of a thing, and Form is (more or less) how it is arranged. To put it another way, Matter is the material stuff that makes something what it is, and Form is the immaterial stuff that makes it how it is.
So, why is this important to note? Well, for a human being, the Matter is our body, and the form is our soul. So, as long as we have something that is human material (read, fertilized egg), we have the human form, aka, a soul. Don't believe me? The difference between a living thing and a dead thing is the presence of an animating principle (soul). Still don't believe me, I challenge you to come up with a material way of describing the difference between a living organism and a dead organism.
Now, your friend clearly isn't a philosopher, so I will correct her mistake as well. An animal has an animal body, and as a result, an animal soul. When the cow dies, the cow's soul goes with it. The difference is that a human being has an immaterial and thus immortal soul, and as a result, should be treated differently.
Before you go and deny that humans have an immortal soul, I point to the fact that it is the operation of an immortal soul to come to some notion of God (an immortal being). Every person I know has some notion of God. The Atheist has to have one so that he can deny it, and the agnostic has to come to a notion of God in order to be not sure about it. The cow can't say "I wonder about what there was before I existed" (an action that is uniquely human) but the cow can seek good grass to convert into methane and manure.

When you ask for a definition you're asking someone to put exact borders around an idea and say "everything on this side is x, everything on the other side is not x". If you're talking about a case right on the edge, this degree of precision may be a necessary. For example: is a virus alive? Tough question. But no one seriously asks "is bacteria alive" unless they are being philosophical or unnecessarily obtuse.
As far as your rejection of the analogy, I have to wonder if you know what an analogy is. When something can be agreed by analog, it means that two things are similar, but not the same. So, setting aside your questionable characterization of an embryo as "a group of embryonic cells", your point that an embryo is not a bacteria is rather odd. Of course it's not. If it was the same, it wouldn't be an analog, would it?
It's pretty clear that what is going on is that you are playing the part of a good reactionary. You have, for whatever reasons, a strong emotional attachment to the abortion issue. You see the argument that an embryo is a living human being to threaten your position and so you react. Your logic in the reaction has been pretty poor (as indicated by your unapologetic resort to ad hominem and the CAPS LOCK OF ANGRY ANGRY DOOM(tm)).
1. An embryo is alive. Your response: define life. As I've already shown, this is an unnecessary burden. Your other response: an embryo is not a bacterium. True, but hardly relevant.
2. An embryo is a human being. No response so far. And there can hardly be one. I'm waiting (heart racing, I assure you) for the inevitable my liver/sperm/hair is human response. And this is true, but your hair is not a complete human entity, it's a part of one. Same for liver, blood cells, etc.
In any case, the solution to your apparent philosophical crisis is simply to realize that there is, or can be, a distinction between a human being and a person. That an embryo is technically a human being at the point of conception is pretty much beyond question. It's a living and unique instance of the species homo sapiens. The question is whether human rights should be expanded to all human beings (which is my position) or just to "persons" (yet to be defined). If you read the other Slashdot comments, you can see that there are plenty of people who are happy to have more constrictive definitions of "person" that exclude (for example) the mentally handicapped.
