No matter how many times you've posted links to cellmedicine.com glorifying the "thousands of people who have had the treatment and are receiving the benefits" that is not a substitute for well-designed randomized controlled trials which evaluate safety and efficacy. And, despite your ongoing crusade about this, the United States is conducting tons of research in this area. For reasons we have been over 20 times before, proper evaluation of a therapy takes time and controlled studies to document the true magnitude of "benefit" as well as establish the incidence and severity of side effects.
There are several sad examples from the medical history books of therapies that were approved and put into use without adequate study to establish benefit and/or safety, only to be retracted later because they were ineffective and in some cases harmful.
If I gave you a pill yesterday, and you feel better today, does that mean the pill helped you? I don't really know. Maybe you would have felt better today even without the pill. That's why we need randomized, controlled trials - to wash out the placebo effect, the rebound effect, and determine the true benefit of a particular therapy. You'll cite the "thousands of people have gotten this therapy..." line all you want, but we don't know if the cell therapy actually did anything for them until it is tested in a randomized controlled trial (which many U.S. scientists have been / still are working on).
