Gene-edited pig kidney transplanted into a living patient for the first time

In a new test of xenotransplantation, a medical team at Massachusetts General Hospital announced Thursday that, for the first time, it had transplanted a kidney from a CRISPR gene-edited pig into a living patient. Surgeons performed the milestone procedure over four hours on Saturday, March 16, without complications. The organ recipient, a 62-year-old man named Richard Slayman, had previously received a human kidney transplant, but it failed after about five years, requiring him to resume kidney dialysis in 2023.
