I don't think bone marrow works becuase it is a different type of cell, or rather, falls under a different classification of stem cell.
Lueii 说:Revilo 说:No, no it wouldn't. The embryonic stem cells used in research tend to come from excess caused by IVF treatment that would never have become a child anyway. It is not a child, it's a bundle of 50-150 cells. It's like saying every time you ejaculate, you're denying millions of 'children' their chance to live, and the same could also be said about a womans period. You're not denying anyone anything, and it's a skewed view that prevents people looking at the greater picture.Lueii 说:Irony. Saving one mans life at the cost of a childs.
In addition, adult stem cells are also used that come from bone marrow (as is the case in this article if you cared to read it), and as well as that, given the choice which would you rather choose? To alleviate or cure the suffering of untold amounts of people in the future, or to spare embryos destined for destruction or long periods of cold storage until well past the date of any use for anything?
Then why not just use bone marrow?
Your logic fails. It is impossible to wait for potential to come to fruit or not come to fruit, because if it does not, it remains potential and you continue waiting for something that - realistically - could never happen just on the off chance that it does. That is, quite frankly, stupid.
Is eight monthes really that long to wait?

You know, my mate told me I didn't understand irony. Which was ironic really, because we were at a bus stop at the time.kiarj 说:

They did for this particular research/treatment. It can't be used for everything though as they are already somewhat specialised, and it's a lot harder to find/extract them. Even then, the quantities available pale in comparison to those available through embryonic stem cell culture.

Not really what he meant. A large amount (over a third) of zygotes don't even implant after conception so far more are lost to chance than are used in stem cell research. You're assuming that every embryo or fertilised egg will equal a baby, and that simply isn't the case.
Lueii 说:Swadius 说:Potential children are only a possibility. The act of sex is also a potential child. If you don't distinguish between the logical levels of what can be and what actually is, every sperm is a potential child.
Shouldn't you wait for that potential to come to fruit or not come to fruit, rather then hack down the sapling?

They don't pronounce them dead, they just aren't a person, no more than a skin cell is and you shed them all the time.Lueii 说:So people would have financial problems? How much do they spend defending themselves. Why not save themselves the crap and have people like me who find embryonic stem cell research disturbing to donate adult stem cells for free. We'd be more then happy to.
Besides, why not play it safe and wait and see if it developes before judging them dead on sight.

1 - Your god [supposedly] sacrificed himself for people who wouldn't give a damn about who he was.Lueii 说:Above. I disapprove of abortion and thus stem cell reasearch for personal reasons.
I do not like the idea that instead of my mother choosing to allow me to live and be adopted by a wonderful family, I could have been killed and used as a science experiment to maybe cure people who don't give a damn about who I could have been.
That is why I hate both the concepts of abortion and stem cell research

Erm, no it wouldn't. Generally speaking, if you wanted to treat an individual via stem cells you'd ideally use the ones already present in their own body, for much the same reason a kidney transplant would be so much smoother if we were all equipped with spare kidneys. In fact you're pretty limited to what you could practically achieve using fetal stem cells; anyone with a high school knowledge of biology should be able to tell you why you'd generally not want to be using fetal cells to rebuild the immune system.Lueii 说:It would have been a child. Never had the chance to be one though.
We can grow stem cell cultures in the lab these days.Suspect-Device 说:I thought they pulled a lot of stem cells out of the placenta without damaging babies anyhow.
