Transplanted Pig Kidney Still Working After a Record-Setting 9 Months in a Patient

Gene-edited pig kidneys could offer a lifeline to patients stuck waiting for a human donor. A woman has lived with a pig kidney for more than nine months without needing dialysis, a record-setting achievement. The woman underwent the operation at Massachusetts General Hospital on November 22 last year. As of Thursday, the kidney has been functioning for 285 days, according to Cambridge, Massachusetts-based eGenesis, the biotech company that used Crispr gene editing to make the organ fit for human transplantation. Previously, the record for a person living with a transplanted pig kidney was 271 days, set by Tim Andrews. Most people in need of a kidney transplant wait three to five years on average to receive one, though it can take longer depending on blood type and other factors.
