The Food and Drug Administration has received a complaint against the company that stored adult stem cells used by Texas Gov. Rick Perry in an experimental procedure last year.
A University of Minnesota professor called on the FDA to investigate Houston-based Cell Tex Therapeutics, a company which banks adult stem cells for future use in medical procedures.
"This plan conflicts with FDA regulations governing human stem cells," states professor Leigh Turner in an 8-page letter to the agency.
While pursuing the Republican presidential nomination last fall, Perry revealed he that had stem cells taken from fat in his own body and then injected into his back during a July operation to treat back pain.
Adult stem cells treatments are not FDA-approved, but experimentation by doctors is common.
