Stem cell therapy, is it approve in the u.s?

Stem cell therapy: It involves the use of stem or pluripotent cells that, under the proper triggers, can grow into many different cell types. Stem cells are transplanted to replace damaged cells or tissues in the body that are unable to heal themselves. While this type of therapy does offer hope, it is mostly investigational at this time and very few stem cell therapies have been proven to be both safe and effective.

Stem Cells: Adult stem cells have helped Leukemia, lymphoma. We have been using limbal stem cell transplants in eye surgery for years with excellent results. See eyedoc2020@blogspot.com. Stem cell injections are now being used to treat painful joints (shoulders, hips, etc), Alzheimers, ALS, Lyme, Cerebral Palsy, etc. Still there are not great published studies proving its benefit in many of these condition.
