A 71-year-old Chinese man survived 171 days after receiving a genetically modified pig liver transplant, marking a milestone in xenotransplantation.
A 71-year-old man in China became the first person to receive a therapeutic transplant of a genetically modified pig liver, marking a milestone in xenotransplantation.
The patient, ineligible for a human liver transplant due to hepatitis B and liver cancer, lived 171 days after the procedure.
The pig liver, from a gene-edited Diannan miniature pig, functioned effectively for the first month, supporting key liver functions.
However, he developed xenotransplantation-associated thrombotic microangiopathy, a severe clotting disorder, which contributed to his death.
Researchers confirmed the pig liver could sustain human metabolic functions for months, demonstrating feasibility while highlighting ongoing challenges with immune and coagulation responses.
The case represents a major step forward in addressing the global shortage of human organs, though further research is needed before such transplants can be widely used.
