"Gene-edited pig kidney transplant keeps monkey alive for over two years, offering hope for organ transplant patients"

A genetically engineered pig kidney successfully kept a monkey alive for over two years, marking a significant step forward in xenotransplantation. The study involved extensive genome edits to prevent immune rejection and neutralize ancient viruses in the donor's organs. The research provides valuable data for regulators considering human trials of non-human organ transplants. However, there was variation in the success of the transplants, and the feasibility of mass-producing pigs with extensive editing remains a challenge. While the survival times were more varied than expected, researchers believe that genetically modified pigs could fare better in humans.
