World’s longest pig kidney transplant in human fails after 4 months

Towana Looney received a gene-edited pig kidney in November 2024. The transplant lasted a record 4 months and 9 days. However, her immune system rejected the organ. Doctors removed the kidney on April 4. Looney expressed gratitude for the research opportunity. Pig organs offer a potential solution to the human organ shortage. Xenotransplantation faces challenges like rejection and virus transmission.
