It probably won't matter, though, as wonderful breakthroughs like this one will be used used to lobby for billion-dollar ESC boondoggles. "See? Embryonic stem cells have such promise!"
I looked to see the source and sure enough, it was bone marrow. The MSM and all the little actors and actresses that champion government funds and ESVs fail to realize where the real promise is.
Government funds should be out because there’s plenty of money to be made from research in this field. ESVs should be out because using them is unethical. But then we can’t expect a group of people in an industry that shuns any pretense of ethics, to understand why there might be a need for them.
