Richard “Rick” Slayman made history on March 16 by becoming the first living person to receive a genetically modified kidney — from a pig.
The 62-year-old Weymouth, Massachusetts, resident had end-stage kidney disease and was running out of options. In 2023, the kidney he received about five years before from a human donor started to fail; he was placed on dialysis but experienced complications that required frequent hospitalization.
That’s when his doctors at Massachusetts General Hospital in Boston suggested an experimental pig kidney transplant. “I saw it not only as a way to help me, but a way to provide hope for the thousands of people who need a transplant to survive,” Slayman said in a statement released by Massachusetts General, where the transplant was performed.
This is just one example of a groundbreaking medical advance that could one day help countless older adults. Here’s a closer look at it, plus two other recent breakthroughs announced in early 2024.
1. Transplanting a kidney from pig to patient
Taking an organ from one species and transplanting it in another — called xenotransplantation — is what Steven Potter, M.D., describes as “one of the holy grails in transplantation” science. A big reason: There is not enough supply from human organ donors to meet demand. About 17 people die each day waiting for an organ transplant, according to the Health Resources & Services Administration.
A kidney is the most common organ needed for transplant, and demand is only expected to increase alongside accelerating rates of end-stage kidney diseasein the U.S. Currently, nearly 808,000 people in the U.S. are living with end-stage kidney disease. Most kidney transplant recipients are between the ages of 45 and 65, according to Cleveland Clinic. For these people, a transplant is the ideal treatment, as it can drastically improve an individual’s quality of life, says Potter, director of pancreas transplantation at Medstar Georgetown Transplant Institute. Dialysis — an expensive therapy where a machine takes on the work for the kidneys — is the other option.
