Scientists transplanted the kidney of a mutant pig into a dead woman Surgeons at the Langon Medical Center at New York University have transplanted a kidney from a genetically modified pig to a human for the first time. Scientists have blocked in the tissues of the animal a molecule that causes organ rejection during transplantation, so the kidney successfully engrafted. The operation was performed on a patient diagnosed with brain death and renal dysfunction. She was on a life support apparatus. The woman's family agreed to an experiment before disconnecting a relative from medical equipment. The surgeons connected the kidney to the blood vessels. After that, the patient's abnormal creatinine levels returned to normal. The woman's body did not reject the organ three days later, it continued to function.
