Japan Osaka University researchers from the patient's oral mucosal cells from stem cells, cultured treatment eye corneal epithelium injury, a success.
Human cornea consists of 5 floors, the outermost that thick about 50 micron non-keratinizing squamous epithelium called corneal epithelium. Corneal epithelial due to sickness or injury suffered injury often leads to blindness, though may through the transplant surgery, but available for transplantation of cornea has always been in short supply. According to the common social recently reported that in March 2003, Osaka University lecturer he fortunately II accepted four 50 to 80 years of corneal epithelium injury, nearly blind patients. Finally the first cut in patients mouth a little mouth mucous membrane, then extracted to isolate stem cells. After two weeks of training, stem cells into the film, its transparency, and corneal epithelium are very similar. Finally the film implant eye. One year after surgery, patients with low vision rehabilitation in good condition, in which a patient's vision 0.7.
