Something is missing from this article. It's talking about treatments involving <i>adult</i> stem cells. The controversy (and heavy regulation) in the U.S. concern <i>embryonic</i> stem cells. In particular, under GW Bush, federal funding for experimentation involving embryonic stem cells that were not from approved lines, was prohibited in the U.S. But there is nothing controversial about adult stem cells, nor anything about them that is specially prohibited.<p>Now, perhaps human medical treatments and experimentation are over-regulated in the U.S. But that has nothing to do with stem cells.<p>And so I suspect this article is complaining about the wrong thing. Whatever problems it is pointing out, are really unrelated to any issues surrounding stem cells.
