Pituitary Grown From Embryonic Stem Cells

Chalk up another part of the body that can be grown from stem cells – at least in mice. Scientists in Japan have induced mouse embryonic stem cells to form a pituitary in the lab. The team’s success not only holds promise for people with pituitary defects, but it’s another of just a few examples in which stem cells have been coaxed into a complex, three dimensional structure.
