Scientists grow human organs in animals to address transplant shortages

Scientists are growing human organs in animals, a breakthrough that could address the critical shortage of transplantable organs. A new study details a method to disable an animal's immune response, allowing human cells to integrate better in hybrid embryos, advancing the creation of human-animal chimeras. This research builds on previous work and comes as xenotransplantation, using organs from genetically modified animals, sees increasing success in clinical trials.
