Doctors question Perry's stem cell back treatment

The July stem cell procedure that Gov. Rick Perry had was an unusual experiment to fix his bad back.

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.
