Genetically Modified Pig Kidney Keeps Patient Off Dialysis for Record Nine Months
A genetically modified pig kidney functioned in an American patient for a record nine months, keeping him off dialysis while awaiting a human transplant. The milestone strengthens hopes that xenotransplantation—using animal organs in humans—could eventually help address the severe worldwide shortage of transplantable kidneys and other organs.
Demand for donor organs greatly exceeds supply. If genetically engineered animal organs eventually prove safe and durable, xenotransplantation could transform treatment for patients with end-stage organ failure.
Researchers need longer-term clinical evidence to understand rejection, infection and durability. Further trials will determine whether genetically modified pig kidneys can become a practical bridge—or eventually an alternative—to human-organ transplantation.
