Question

Quizplus · Accepted Answer

The major obstacle to the use of xenotransplants is organ rejection by recipients. This occurs because the immune system recognizes foreign tissues as non-self and mounts an immune response, leading to rejection and failure of the transplant. While some progress has been made in developing genetically modified pigs that are more compatible with human recipients, organ rejection remains a major challenge to widespread use of xenotransplants.
