Seeing with stem cells

ICYMI, we’ve been seeing some cool stuff with stem cells recently. The latest is a possible treatment for macular degeneration—the leading cause of blindness in the UK. Essentially, the part of your eye that lets you see what’s directly in front of you (the macula) gets worse over the years like an iPhone hardware update. You know, subtle changes at first, then it’s just objectively worse than it was before (stages of macular degeneration here.) But using an embryonic stem cell patch inserted into the back of the patients’ eye, failing macula cells can be replaced to restore partial vision. Two patients in a Phase I study have experienced improved vision for about a year, and eight more patients will be part of the ongoing study
