Every ten minutes, a person is added to the national waiting list for organ transplants. And every day, 22 people on that list die without the organ they need.  Juan Carlos Izpisúa Belmonte, a Salk Institute research, wrote an article for the November 2016 issue of Scientific American describing his dream of using chimeric animals to grow human organs for patients needing transplants. Earlier today, a report in the journal Cell emerged that researchers at the Salk Institute had, for the first time, successfully created human/pig chimera embryos. A big step toward solving the organ donor shortage!
