Could synthetic stem cells mean the end of certain forms of blindness?
Scientists at the University of Wisconsin have created basic retina structures, giving hope to many with eye damage that their vision could be repaired someday.
The retina structures were created by synthesizing stem cells from a patient's blood, and successfully sent important information to the brain that helps humans see.
Scientists can create the stem cells from a simple blood test, and the ability to build the retina structures from the cells—and isolate which layers need repair—will allow researchers to further study degenerative diseases like retinitis pigmentosa.
The study is still in its primordial phases, but it could lead to some big leaps forward in research and maybe even some day the ability to generate new cells for patients whose eyes are going bad. Just think: Someday grandma may stop asking you where she put her reading glasses!
