U.S. researchers use 3D bioprinting to create eye tissue

LOS ANGELES, Dec. 22 (Xinhua) -- U.S. researchers have used patient stem cells and 3D bioprinting to produce eye tissue that will advance understanding of the mechanisms of blinding diseases, the U.S. National Institutes of Health (NIH) announced on Thursday.

The research team from the U.S. National Eye Institute printed a combination of cells that form the outer blood-retina barrier -- eye tissue that supports the retina's light-sensing photoreceptors.
