Doctors question Perry's stem cell back treatment

The GOP presidential candidate had stem cells taken from his own fat, grown in a lab and injected back into him.

The Associated Press today reports at least one patient outside the U.S. died of a clot hours after an infusion of fat-derived stem cells.

Perry's doctor, orthopedist Stanley Jones, couldn't be reached for comment despite repeated requests.

Jones told the Texas Tribune that he went to Japan for a stem cell treatment for his arthritis and he'd never before tried the procedure he used on Perry. Jones also said it had no side effects or risks.

A Perry spokesman says the governor consulted with his physician and is pleased with the results.
