Scientists successfully transplanted a genetically modified pig lung into a brain-dead person, keeping it functional for nine days. This xenotransplantation—using animal organs to replace human ones—aims to address the critical organ shortage. While promising, experts emphasize it's a preliminary step. The pig lung showed some damage and inflammation despite immunosuppressants. Further research is needed to improve genetic modification, immunosuppression, and organ preservation before this technique can be used in living patients. Other approaches, like modifying human donor lungs or growing human organs in animals, are also being explored.
