Scientists grow human eye parts to determine how we see in color
Researchers at John Hopkins University in Maryland created eyeball parts from stem cells in the hopes of better understanding the how and why we developed "trichromatic vision" -- the ability to see in red, blue and green. The study was published in Science on Oct. 12.
Organoids are built in vitro from a small number of stem cells in a 3D suspension, which eventually multiply to form something akin to an organ system.
The eye organoid used in the John Hopkins study produces a miniature retina, the layer of cells at the back of the eyeball that process light, creating the electrical impulses the brain can use to produce vision.
