Abstract
A corneal epithelial sheet having a cell layer similar to the anterior epithelium of cornea. A corneal epithelial sheet is obtained through the step (a) of separately preparing a first cell being a self cell and a second cell whose origin is different from that of the first cell, the step (b) of planting the first cell and the second cell on a collagen layer and culturing them, and the step (c) of after proliferation of the cell and second cell resulting in formation of a cell layer, bringing the outermost stratum of the cell layer into contact with the air.
