The initial recipient of a kidney transplant from a genetically modified pig has passed away nearly two months following the groundbreaking procedure, as confirmed by his family and the hospital where the operation took place.


Richard “Rick” Slayman, aged 62, underwent the pioneering transplant at Massachusetts General Hospital in March. Surgeons had expressed optimism, believing the pig-derived kidney would provide functionality for a minimum of two years.


Expressing profound sorrow, the transplant team at Massachusetts General Hospital conveyed their condolences to Slayman's family, emphasizing that there were no indications suggesting his demise was linked to the transplant.


Hailing from Weymouth, Massachusetts, Slayman made history as the first living recipient of such a procedure. Prior to this, pig kidneys had only been temporarily transplanted into brain-dead donors. Though two individuals had received heart transplants from pigs previously, both succumbed within months.


Slayman had undergone a kidney transplant at the same hospital in 2018, reverting to dialysis last year due to signs of kidney failure. Subsequent complications necessitated frequent procedures, prompting his medical team to propose a pig kidney transplant.


In a statement, Slayman’s family expressed gratitude towards his medical team, acknowledging their tireless efforts in pioneering xenotransplantation, which afforded them seven additional weeks with Rick, cherished moments that will forever remain in their memories and hearts.


The family underscored Slayman's motivation for undergoing the surgery, stating it was to instill hope for the countless individuals awaiting transplants to prolong their lives.


“Rick accomplished that goal and his hope and optimism will endure forever,” the statement concluded.


Xenotransplantation, the practice of utilizing animal cells, tissues, or organs to treat human patients, has historically faced challenges due to immune rejection. Recent advancements, however, have focused on modifying pig organs to closely resemble human counterparts.


With over 100,000 people on the national transplant waiting list, primarily kidney patients, and thousands succumbing annually before receiving a transplant, the need for innovative solutions remains paramount.
