Interventions/Control_1

Harvest of the oral mucosal tissue is conducted at the University of Tokyo Hospital. The tissue is transferred to Osaka University Hospital, and oral mucosal cell sheets are produced. The produced sheets are transferred back to the University of Tokyo Hospital, and transplanted to the cornea defected corneal epithelial stem-cell; then graft survival and stabilization of epithelial cells are attained.
