I read this to mean essentially embryonic cells which we already know and have known for years have all kinds of problems our own adult stem cells do not. If this article is implying that autologous stem cell therapies should be shut out, I completely disagree. Look at Dennis Turner, and that guy on the PBS show who got his own cells implanted in Canada....true, those new cells may ultimately become infected with PD, whatever we find it to be, but it did buy those guys many good, good years of better health than they would have had on the same old, same old drug regime. And those are just two.

I want the choice to have stem cells as a treatment, if for nothing else than to buy time, since it is more than clear that the drug companies are in no hurry to help us.
