Closing the Organ Deficit

Izpisua Belmonte is addressing the shortage of human organs for transplant with a scientifically innovative—albeit ethically controversial—solution: growing human cells in animal embryos to produce, say, human liver tissue inside a living pig or non­human primate, which can then be transplanted into people. It’s the first step toward growing enough human organs without relying on human donors. —Alice Park
