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.
This type of thing has been being worked on for awhile and I sorta feel we will have 3d printed at this point by the time this is fully working.
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.
