The Arrow's Path

I ran across this very bizarre article on CNNSI.com about stem cell research and sports medicine. Particularly, the article is a first person account of a former pitcher's attempt to basically rebuild his arm after injury through a strange concoction of stem cell therapy and PRP therapy. I have read through the article more than once, and I still don't know what I think about, other than to say that I think it brings up a whole host of medical ethics questions. From a sheer medical standpoint, the whole procedure sounds almost fantastical, to the point of being some combination of crackpot medicine and science fiction. A scant $5000 for a miracle one time therapy that can allow a washed up pitcher to regain throwing ability in the 90+ MPH range in six weeks? That seemed kind of out there to me, but there was just enough logic to it that maybe there is medical merit to the procedure. I'm not a doctor, so I can't really speak to that other than from a common sense ...
