Scientists have developed an experimental technique for repairing damaged lungs by sharing their circulatory system with living pigs. This research has shown promise in restoring damaged human lungs, potentially increasing the number of viable organs available for transplant. While the technique is not yet ready for clinical use due to potential disease transmission from pigs to humans, the researchers believe it opens the possibility for investigating and recovering other organs as well. This innovative approach could address the current shortage of suitable donor organs and improve the success rates of lung transplants.
