1. Genetic Modifications – Scientists edit pig genes to prevent immune rejection and insert human genes to improve compatibility for transplantation.
  2. Successful Transplants – A genetically modified pig heart (2022) and pig liver (2025) were transplanted into humans, showing short-term functionality without immediate rejection.
  3. Future Potential – These organs could act as temporary support for patients waiting for human transplants, but long-term success and full organ functionality need further study
