I had my first kidney transplant in 2004. It gave out after 10 years. The replacement, which I received in 2016, functions well but won’t last forever. “May your organ outlive you,” older transplant patients tell each other. Otherwise, you may not survive the queue for a new one.
That’s why recent breakthroughs in xenotransplantation—the implantation of animal tissues and organs across species—have been exhilarating. In September, doctors at NYU Langone Medical Center attached a pig kidney to blood vessels in a dead woman’s leg (with her family’s permission). It produced urine and cleared waste products during the 54-hour observation period. Two months later, they repeated the procedure.
Also in September, a team at the University of Alabama at Birmingham implanted the first-ever genetically modified pig kidneys into the body of Jim Parsons, 57, of Huntsville, who had been left brain-dead by a motorcycle accident. The new kidneys turned “beautiful and pink,” the lead surgeon said. The experiment lasted 77 hours.
Then, on Jan. 7, surgeons at the University of Maryland transplanted a heart from a genetically modified pig into David Bennett Sr. , who doctors said had exhausted all other treatment options. Mr. Bennett, 57, is still alive.
More than 90,000 Americans are waiting for a kidney. In 2021 fewer than 25,000 received one, and some 41,000 were added to the national waiting list. On the average day, around a dozen people on the list die.
