Patients blinded in one or both eyes by chemical burns regained their vision after healthy stem cells were extracted from their eyes and reimplanted, according to a report by Italian researchers at a scientific meeting.
The tissue was drawn from the limbus, an area at the junction of the cornea and white part of the eye. It was grown on a fibrous tissue, then layered onto the damaged eyes. The cells grew into healthy corneal tissue, transforming disfigured, opaque eyes into functioning ones with normal appearance and color, said researchers led by Graziella Pellegrini of the University of Modena’s Center for Regenerative Medicine.
