When it comes to the future of medicine, few therapies get people as excited as stem cells.
Researchers are looking at them for future treatment for diseases like Parkinson's, Alzheimer's, Type 1 Diabetes and more. But the key word is "future." Progress with stem cell therapies has been slow and the few clinical trials taking place are in their infancy.
Yet despite the lack of FDA-approved treatments, stem cell clinics — which promise cures for conditions as varied as arthritis, pulmonary disorders and orthopedics — are popping up all over the country.
The clinics say they’re doing nothing wrong. But researchers call the treatments the equivalent of "snake oil," saying at best they can waste money and at worst do permanent damage.
Dr. Paul Knoepfler of the University of California, Davis joins Here & Now's Robin Young to discuss this new industry, and his recently published online study about unregulated clinics in the journal Cell Stem Cell.
