But transplanting entire organs is much more complex than using highly processed tissue. Pigs have long been used in human medicine, including pig skin grafts and implantation of pig heart valves. And surgeons at the University of Alabama at Birmingham went a step further, transplanting a pair of gene-edited pig kidneys into a brain-dead man in a step-by-step rehearsal for an operation they hope to try in living patients possibly later this year. Twice last fall, surgeons at New York University got permission from the families of deceased individuals to temporarily attach a gene-edited pig kidney to blood vessels outside the body and watch them work before ending life support. One next question is whether scientists have learned enough from Bennett's experience and some other recent experiments with gene-edited pig organs to persuade the FDA to allow a clinical trial - possibly with an organ such as a kidney that isn't immediately fatal if it fails. Shots - Health News In the quest for a liver transplant, patients are segregated by prior alcohol use But more than 106,000 people remain on the national waiting list, thousands die every year before getting an organ and thousands more never even get added to the list, considered too much of a long shot. last year, a record - including about 3,800 heart transplants.

He proved to be a brave and noble patient who fought all the way to the end," Dr. Last month, the hospital released video of him watching the Super Bowl from his hospital bed while working with his physical therapist.īennett survived significantly longer with the gene-edited pig heart than one of the last milestones in xenotransplantation - when Baby Fae, a dying California infant, lived 21 days with a baboon's heart in 1984. 1A Could Animals Be The Solution To America's Organ Problem?Īt first the pig heart was functioning, and the Maryland hospital issued periodic updates that Bennett seemed to be slowly recovering.
