xenotransplantationTransplantation of organs from animals, usually transgenic animals, especially pigs, specifically engineered for the purpose. Until recently, no transplanted pig organ had survived for more than a month. But advances in the development of new immunosuppressive agents against xenografts and the identification of the main target for human xenoreactive (anti-pig) antibodies have extended this period to an average of 76 days. Precautions can also be taken against virus transmission. The future for xenotransplantation seems bright.
