![]() Dorry Segev, a professor of transplant surgery at Johns Hopkins School of Medicine, told the Times. "We need to know more about the longevity of the organ," but this "is a huge breakthrough. "Whether this particular study advances the field will depend on what data they collected and whether they share it, or whether it is a step just to show they can do it." Jay Fishman, associate director of the transplantation center at Massachusetts General Hospital in Boston, told the Times. "There's no question this is a tour de force, in that it's hard to do and you have to jump through a lot of hoops," Dr. Many questions remain, but experts called the procedure a milestone. The patient was followed for only 54 hours and the research hasn't been peer-reviewed or published in a medical journal, but it hints at a new source of desperately needed transplant organs. A lot of kidneys from deceased people don't work right away, and take days or weeks to start. "It just looked like any transplant I've ever done from a living donor. "It was better than I think we even expected," he told the Times. The results strongly suggest that this type of organ will work in the human body, according to Montgomery. Robert Montgomery, the director of the NYU Langone Transplant Institute who performed the procedure, the Times reported. ![]() After being attached to the blood vessels in the upper leg outside of the patient's abdomen, the kidney quickly started functioning normally, said Dr. The big prize: There is a dire need for more. The kidney came from a pig genetically engineered to grow an organ with a low risk of being rejected by the human body. Researchers on Thursday reported the latest in a surprising string of experiments in the quest to save human lives with organs from genetically modified pigs. The pig was genetically engineered by Revivicor, one of several biotech companies working to develop pig organs to transplant into humans. The surgery was conducted in September at NYU Langone Health in New York City and involved a patient who was brain-dead and being kept alive on a ventilator, The New York Times reported. Doctors transplant a genetically modified pig heart into a human for the 1st time January 10, 20224:48 PM ET The Associated Press Enlarge this image In this photo provided by the University. If the technique proves generally successful it could revolutionize organ transplant, greatly expanding the pool of available organs. However, if the pig is genetically modified by deleting the targets for the initial human rejection response, and by introducing human protective genes, pig. 20, 2021 (HealthDay News) - A kidney grown in a genetically altered pig functioned normally after being attached to a human patient during a groundbreaking procedure performed by U.S. What they're saying: "We are proceeding cautiously, but we are also optimistic that this first-in-the-world surgery will provide an important new option for patients in the future," said Bartley Griffith, the surgeon who performed the operation.WEDNESDAY, Oct. The FDA granted emergency authorization for the surgery on New Year's Eve for this operation, in the hopes that it would save Bennett.I know it's a shot in the dark, but it's my last choice," Bennett said, per UMMC. "It was either die or do this transplant.Xenotransplants were first tried in the 1980s but were abandoned soon after.ĭetails: Bennett, the patient, had been deemed ineligible for a standard heart transplant.This type of transplant, known as xenotransplantation, was pioneered at Maryland by Muhammad Mohiuddin. ![]() The surgery has the potential to provide hope to hundreds of thousands of patients worldwide, the New York Times notes.Ĭontext: Around 110,000 Americans are waiting for an organ transplant and more than 6,000 die each year before receiving one, according UMMC. Why it matters: The patient, 57-year-old David Bennett, is still doing well three days later, proving for the first time a "genetically-modified animal heart can function like a human heart without immediate rejection by the body," UMMC said. For the first time, a patient with life-threatening heart disease received a heart from a genetically modified pig, the University of Maryland Medical Center announced on Tuesday.
