Scientists Regrow Retina Cells to Tackle Leading Cause of Blindness Using Nanotechnology

Posted by in categories: biotech/medical, nanotechnology

Regrowing the cells of the human retina on a scaffold of synthetic, tissue-like material showed substantial improvements over previously used materials such as cellulose, and the scientists hope they can move on to testing their method in the already blind.

Macular degeneration is increasing in prevalence in the developed world. It’s the leading cause of blindness and is caused by the loss of cells in a key part of the eye called the retina.

Humans have no ability to regrow retinal pigment cells, but scientists have determined how to do it in vitro using pluripotent stem cells. However as the study authors describe, previous examples of this procedure saw scientists growing the cells on flat surfaces rather than one resembling the retinal membrane.
