I don't like to be the one to say this, but my understanding is that stem cell treatment has never cured any illness. I guess those in the know feel that the benefits of trying it are going to suddenly blossom in to success. But as of today, stem cell therapy is unproven, but that doesn't stop people from promising miracle cures in some countries. I read on Quora.com that someone asked the question, "Does stem cell therapy work?" One response was, "The short answer is no. We do not have a good enough protocol to safely inject stem cells and control their differentiation in vivo."
