A new cell injection technique could help reverse vision loss. Millions of people around the world live with reduced vision due to conditions such as Age-related Macular Degeneration (AMD) or Retinitis Pigmentosa, both of which are caused by the loss of cells in the Retina, at the back of the eyeball. Over time, many researchers have experimented with injecting healthy cells to replace the dead cells, but integrating the new cells into existing tissue is a major challenge, and most injected cells end up dying as well. But a new delivery method for injecting not only dying photoreceptor cells, the cells responsible for vision, but also Retinal pigmented epithelium (RPE) cells, has shown that mice who received the co-injection regained 10% of their normal visual acuity. Initial tests are promising, but extensive further testing in animal models will be required before trials on humans can begin. Learn more at https://bit.ly/3b6aSq7
