Novel cell injection method could help reverse vision loss

A team of researchers at University of Toronto Engineering (Canada) have developed a novel approach to inject healthy cells into damaged eyes. The study, published in Biomaterials, demonstrates that co-injection of both retinal pigmented epithelium (RPE) cells and photoreceptor cells in a mouse model of blindness helped recover some of their normal visual acuity. This approach could pave the way towards new treatments to help reverse some forms of vision loss. Age-related macular degeneration (AMD) and retinitis pigmentosa often result in vision loss, and both are caused by the death of retinal pigmented epithelium (RPE) cells. Previous studies in the...
