Researchers are exploring the use of gene-edited pigs as a potential solution to the organ transplant shortage. Scientists have made progress in understanding the immune reaction behind pig organ rejection in transplant patients, and some experts believe that pig organ transplants could one day be superior to human ones. The concept of using gene-edited pig organs for transplants, known as xenotransplantation, is entering real-world trials, with some institutions and organizations expressing support for the approach.
