Researchers Create a Pituitary Gland from Scratch

• Technology Review

Last spring, a research team at Japan's RIKEN Center for Developmental Biology created retina-like structures from cultured mouse embryonic stem cells. This week, the same group reports that it's achieved an even more complicated feat—synthesizing a stem-cell-derived pituitary gland.

The pituitary gland is a small organ at the base of the brain that produces many important hormones and is a key part of the body's endocrine system. It's especially crucial during early development, so the ability to simulate its formation in the lab could help researchers better understand how these developmental processes work. Disruptions in the pituitary have also been associated with growth disorders, such as gigantism, and vision problems, including blindness.

The study, published in this week's Nature, moves the medical field even closer to being able to bioengineer complex organs for transplant in humans.
