Was that really necessary? Especially since you didn't bother to post anything other than your attack to back it up?
I don't have a dog in this hunt. Last word I heard is that undifferentiated stem cell lines were the center focus of this type of research as they more readily "become" other cells. Adult cells, while they have their uses, are not as readily workable, nor are the applications as broad.
If I am mistaken in my assumptions, then point me to some more research and let me go read up. Don't just wade in with the insults.
