Researchers plan to track the organ's performance for a second month. It's another step in the long quest to one day use animal organs to save human lives. More than 100,000 patients are on the nation’s transplant list and thousands die each year waiting.
My bet is on the animal organ technology getting to market first. Although the experiments with printing human heart cells on top of the stripped cartilage from a pig’s heart looks promising. Best of both tech.
