We succeeded in culturing primary cor neal limbal epithelial cells taken from minimal biopsy and,once grown, transplan ting them on denuded amniotic membrane (AM). Methods: Autologous corneal limbal epithelial cells from a 3 mm2 biopsy of the uninjured eye were grown for 3weeks on a denuded AM carrier. The resultant sheet was then transplanted onto the unil ateral severely chemically injured eye. Results: Minimal biopsy showed the autol ogous cultivated corneal epithelial cells to have 4-5 layers of sufficient stra tification and to be well differentiated. At 19 months post-transplantation, th e ocular surface epithelium was stable and there were no epithelial defects. Con clusion: We document that it is possible to produce sufficiently stratified, wel l differentiated, autologous cultivated corneal limbal epithelium on AM from a m inimal biopsy of the donor eye and to transplant it onto the injured eye.展开更多
