An experimental treatment for blindness, developed from a patient’s skin cells, improved the vision of blind mice in a study conducted by Columbia ophthalmologists and stem cell researchers.Central vision is lost in age-related macular degeneration after cells in the retina deteriorate. New research by Stephen Tsang suggests special adult stem cells could restore sight or prevent vision loss.The findings suggest that induced pluripotent stem (iPS) cells – which are derived from adult human skin cells but have embryonic properties – could soon be used to restore vision in people with macular degeneration and other diseases that affect the eye’s retina.To see more details visit,www.healthcanal.com
