NEW YORK (AP) — Doctors in Boston say they have transplanted a pig kidney into a 62-year-old patient.

Massachusetts General Hospital said Thursday it’s the first time a genetically modified pig kidney has been transplanted into a living person.

Previously pig kidneys have been temporarily transplanted into brain-dead donors.

Also, two men received heart transplants from pigs, although both died within months.

The hospital announced the transplant Thursday and said the patient is recovering well.
