why do you keep posting this and not mentioning that it was all tied to those countries teaching abstinence only education, which almost certainly increased the rate of HIV infection?
not yet and that's probably not where their primary application will lie. (it doesn't make sense, for example, to treat rapidly reproducing cells with...more cells?) however, they're already using them to grow peoples' jaws back and human cells were used in rats to repair spinal chord damage in rats so it's difficult to say this is anything but the most promising and exciting breakthrough in medicine since, oh, I don't know, daily baths.
Provide a link, please ... according to the NIH, stem cells have not been used to cure these diseases as of yet. They have been used to treat some diseases.
