(STUDY FINDS) – Vision is easy to take for granted, but just the thought of blindness is enough to terrify many people. Unfortunately, modern medicine offers frustratingly few treatment options once blindness sets in. However, researchers from the University of Wisconsin-Madison have made a stem cell breakthrough that could finally lead to a cure for degenerative eye disorders.
Scientists successfully demonstrated that retinal cells grown from stem cells are capable of “reaching out and connecting” with their neighboring cells. This cellular handshake, if you will, suggests that the cells are ready for clinical trials in humans dealing with vision loss, study authors adds.

Over a decade ago, researchers at UWM developed a way to grow organized clusters of cells (organoids), that resemble the retina – light-sensitive tissue at the back of the eye. Scientists then coaxed human skin cells reprogrammed to act as stem cells to develop into layers of numerous types of retinal cells that sense light, ultimately transmitting what we see to our brains.
