ANTERIOR OCULAR-ASSOCIATED CELL SHEET, THREE-DIMENSIONAL CONSTRUCT AND PROCESS FOR PRODUCING THE SAME

摘要

It is intended to provide an anterior ocular-associated cell sheet or a three-dimensional construct with little structural defects which can be recovered in a state of sustaining cells, the intracellular desmosome structure and basal lamina-like proteins among cells and base material. The anterior ocular-associated cell sheet or the three-dimensional construct can be produced by culturing cells on a cell culture support having a base material surface-coated with a temperature-responsive polymer having an upper limit or lower limit critical dissolution temperature in water of 0 to 80°C, layered the cultured cell layers, if needed, and then: (1) controlling the culture medium temperature to a level higher than the upper limit critical dissolution temperature or lower than the lower limit critical dissolution temperature; (2) if needed, tightly pressing the thus cultured anterior ocular-associated cell sheet or three-dimensional construct to a polymer film; and (3) then peeling off it together with the polymer film.
