Research Abstract

PURPOSE: To determine the feasibility of using human amniotic membrane (AM) as a substrate for culturing oral epithelial cells and to investigate the possibility of using autologous cultivated oral epithelial cells in ocular surfase reconstruction. METHODS: An ocular surfase injury was created in one eye of each of eight adult albino rabbits by a lamellar keratectomy, and a conjunctival excision was performed, including and extending 5 mm outside the limbus. Oral mucosal biopsy spesimens were obtained from these eight adult albino rabbits and cultivated for 3 weeks on a denuded AM carrier. The cultivated epithelium was examined by electron microscopy (EM) and immunohistochemically labeled for several keratins. At 3 to 4 weeks after the ocular surface injury, the conjunctivalized corneal surfaces of the eight rabbits were surgically reconstructed by transplanting the autologous cultivated oral epithelial sheet had four to five layers of stratified, well-differentiated cells. EM revealed that the epithelial cells were very similar in appearance to those of normal corneal epithelium, had numbrane with hemidesmosomes. Immunohistochemistry confirmed the presence of the keratin pair 4 and 13 and keratin-3 in the cultivated oral epithelial cells. Corneas that were grafed with the cultivated oral epithelial cells on an AM carrier were clear and were all epithelialized 10 days after surgery. CONCLUSIONS: cultures of oral epithelial cells can be generated to confluence on AM expanded ex vivo from biopsy-derived oral mucosal tissue. Autologous transplantation was performed with these cuitivated oral epithelial cells onto the ocular surfaces of keratectomized rabbit eyes. Autologous transplantation of cultivated oral epithelium is a feasible method for ocular surface reconstruction
