The first four patients who received transplants of organs from genetically modified pigs

 NBC reports on the four patients who have so far received organ transplants from genetically modified pigs.

Their loved ones died after receiving pig organ transplants. The families have no regrets. Four people have received hearts or kidneys from pigs. Some of their relatives recount a roller coaster of hope and uncertainty. By Aria Bendix

"David Bennett Sr., had severe congestive heart failure and wasn’t a candidate for a human transplant. He knew he would likely die soon. There was nothing more to do — other than take a chance on a novel, cutting-edge surgery. Bennett Sr. and his son agreed it was worth the risk.  

"The achievement made headlines around the world after the transplant surgery in January 2022.

...

"But two months later, Bennett Sr.’s body rejected the heart and he died at age 57. In a paper, his doctors at the University of Maryland Medical Center explained that his body had likely produced too many antibodies that fought off the new organ.

...

Three other patients have followed in Bennett Sr.’s footsteps and received pig organs, most recently a pig kidney transplant in April. Together, they represent the pioneer patients of the burgeoning field of xenotransplantation. For their families, three of which spoke to NBC News about the experience, the journey came with a roller coaster of emotions, from uncertainty to blind hope — and, ultimately, admiration for their loved one’s decision. 

...

"None of the patients survived more than three months. To the public, that might seem like failure. But to the families, the transplants accomplished their goals: to buy their loved ones more time and advance research that could potentially save lives one day."
