The first human kidney transplant of a pig is successfully performed

For the first time, a pig kidney has been transplanted into a human without causing immediate rejection by the recipient's immune system, a potentially major breakthrough that would put an end to the hardships many people face in obtaining an organ and queuing. long waiting.

The procedure performed at a New York City hospital initially involved using a procedure that altered the pig's genes so that his tissues no longer contained molecules that caused immediate rejection by the recipient's body.

The recipient was a patient on clinical death, with signs of renal dysfunction. Her family allowed the experiment to take place.

For three days, the young kidney was held outside its body, giving researchers access to see the functions.

Transplanted kidney function test results 'looked quite normal', said transplant surgeon Dr. Robert Montgomery, who led the study.

The kidney filtered the required amount of urine that was expected after a transplant.

"Abnormal creatinine levels returned to normal after the transplant," said Montgomery.

In the United States, nearly 107,000 people are currently waiting for organ transplants, and more than 90,000 of them are expecting a kidney. The waiting time for a kidney on average lasts three to five years.

Researchers have been working for decades on the possibility of using animal organs for transplants, but usually the human body has immediately rejected them.

The experiment involved a transplant that lasted only three days so any future testing is likely to reveal new barriers that will need to be overcome. Eligibility may also depend on prognosis.
