I don't know why anyone is talking about life expectancy and so forth. We're talking about stem cell therapy, not the Fountain of Youth. Stem cells are promising avenues of treatment for a lot of diseases and conditions... Parkinson's disease, for example, or the provision of replacement organs for people who need them. These don't strike only old people, they strike everyone from children on up.
A few of the posters here seem to completely lack compassion... if your parents, or brother, or sister, or gf/bf/wife/husband were the ones sick and dying -- or just losing control of their bodies as in Parkinson's -- and something could help them, would you really say "oh, stop clinging to life" or "you're not much use to society anymore, anyways." Sheesh.

I don't think there's a "slippery slope." What would you worry it could lead to? The only thing I can think of are grisly "organ-harvesting-from-children" scenarios. But those are completely different... they're clearly wrong; you'll not find
anyone who doesn't think farming humans is messed up. Stem cells and embryos, well, you can't even tell they're human, or embryos, or not like one of the trillions of cells in your body w/o a shitload of scientific analysis.
Embryos are uniquely useful for producing stem cells, and the whole point is they can be coaxed into reproducing into whatever, so you don't gain anything from huge numbers of them. There are many suitable embryos now, from abortion or fertility treatments, which are simply destroyed. Seems to me if using some of them to develop stem cells could do a great deal of good, it's wrong not to try.

Acidfiend makes the best point out of anything said here. We don't have to be using fetuses in the first place, we can use baby teeth or other sources of stem cells, so this whole argument on morality is pretty pointless. Lets just not use fetuses/embryos and use the other sources and avoid the issue.
That's just not true though. I mean, it's not like research biologists are clamoring for embryonic stem cell lines for shits and giggles. It's not like they don't know about these other types of cells. But the cells you get from teeth, etc, are quite different... they've partly differentiated and specialized already. They can't turn into the tissue types embryonic-derived cells can; they're just not the same. It's possible some new breakthrough will make embryonic stem cell lines unnecessary, sure... it's also possible a breakthrough will make
all stem cells unnecessary. Right now, tho...
