Lab-Grown Retina Cells Successfully Transplanted in Mice

A study in Nature Biotechnology reports that “irreversible blindness caused by loss of photoreceptors may be amenable to cell therapy.” Using embryonic stem cells (ESCs), scientists were able to grow new retina cells in a lab, and then placed them into blind mice. Researchers found that these new cells created healthy nerve connections with existing cells, indicating a successful transplantation. This study “shows conclusively that ESCs can provide a source of photoreceptors for retinal cell transplantation.”
