The transplantation of a baboon's bone marrow into an AIDS patient apparently has not succeeded in bolstering the man's devastated immune system. Researchers have been unable to find any evidence that the baboon's bone marrow took root and began functioning inside Jeffrey Getty, the patient received the highly controversial, highly experimental procedure in San Francisco. Critics had been concerned that the transplant, and others like it, could transmit new diseases from animals to humans. But Getty's doctors say they've found no evidence of that either. Getty's prognosis remains uncertain. David Wright reports from member station KQED.
