3-D ‘mini-retinas’ grown from mouse and human stem cells

Stem cell science has progressed so that researchers can now share recipes for making human retinas — the part of the eye that is sensitive to light. Researchers now have another efficient way to make 3-D retina organoids, which mimic the organ’s tissue organization, from mouse or human stem cells. Their version of ‘mini-retinas’ offers new perspectives on retina growth, injury, and repair.
