Mouse retinas grown in lab

Transplanted cells can function in rodents' eyes

EYE CANDY  Researchers grew primitive retinas (one shown, with proteins  that collect and transmit light signals in green and red) by embedding mouse  embryonic stem cells in a gel. Immature cells from the lab-grown structures can  integrate into adult eyes.

Retina cells can be grown from mouse stem cells in the laboratory and become working parts of a mouse’s eye, a new study indicates.
