Xenotransplantation is transplanting animal organs into humans. Researchers are concentrating on making pig hearts, lungs, and kidneys safe by genetically engineering their DNA to be accepted by human immune systems. Last year, the first such heart transplant took place, allowing a man with end-stage heart failure to live for an additional two months. The landmark surgery ignited hope that a future of widely available pig organs could be edging closer for the 100,000+ people in dire need of transplants in the U.S.
