For the first time, the Federal Trade Commission has cracked down on stem cell clinics for overzealous marketing claims, filing a complaint against two California clinics that promoted their treatments for everything from autism to Parkinson’s despite a lack of evidence.

As part of a proposed settlement announced Thursday, the FTC is requiring the clinics — Regenerative Medical Group and Telehealth Medical Group — and their owner, Dr. Bryn Jarald Henderson, to stop making such claims and to inform past and current patients about the settlement.
