A US hospital recently transplanted a pig kidney to a brain-dead patient, which did not immediately cause rejection.

【genetic modification】 According to a Reuters report on the 19th, the New York University Langon Medical Center performed surgery last month
Chief surgeon Robert Montgomery said that because the transplanted pig kidney was genetically modified, the operation did not immediately cause rejection
He said that a sugar molecule called alpha-gal in pig cells can cause human rejection, and the "kidney source" of this operation is a pig that has been genetically modified to remove this sugar molecule, so the patient did not show up.

【Short-term plan】 Three days after the transplant operation, the patient's life support equipment was removed on the scheduled date
The Associated Press quoted Montgomery as reporting that the patient wanted to donate organs during her lifetime, but for some reason her family agreed to let her receive a pig kidney transplant, which allowed her to contribute to medical research in this way
Montgomery said that this operation and previous studies make it possible for patients with advanced renal failure to receive experimental pig kidney transplantation as early as one or two years
Reuters quoted data from the Organ Sharing United Network, a non-profit organization in the United States, reporting that there are currently nearly 107,000 people in the United States waiting for an organ transplant, of which more than 90,000 people are waiting for the source of the kidney, which takes 3 to 5 years on average

Research on transplanting animal organs to humans has been underway for a long time
