Restored Functional Cornea (image) Massachusetts Eye and Ear Infirmary Caption This is a restored functional cornea following transplantation of human ABCB5-positive limbal stem cells to limbal stem cell-deficient mice. Transplants consisting of human ABCB5-positive limbal stem cells resulted in restoration and long-term maintenance of a normal clear cornea, whereas control mice that received either no cells or ABCB5-negative cells failed to restore the cornea.
