Scientists closer to growing human organs in animals

Biologists have announced that, for the first time, they had succeeded in growing human stem cells in pig embryos. It's a huge advance, one that opens the possibility of developing human organs in animals that can later be withdrawn and implanted in humans.

Why this matters: If pigs from such embryos could survive with human organs growing inside them it would open up the possibility of harvesting human organs for transplant that could end the backlog of waiting lists for such organs.
