CULTURED CELL SHEET, PROCESS FOR PRODUCING THE SAME AND METHOD FOR RESTORING TISSUE USING THE SAME

摘要

The problem to be solved by the present invention is to provide a cultured cell sheet having a superior tissue adhesiveness and an excellent flexibility. The problems can be solved by producing the cultured cell sheet in which cells are cultured in the presence of a surfactant protein or a cross-linking inhibitor on a surface of a cell culture support that is coated with a temperature responsive polymer having an upper or lower critical solution temperature ranging from 0°C to 80°C in water, including steps of: adjusting the temperature of the culture medium to a temperature below the lower critical solution temperature or above the upper critical solution temperature; and detaching the cultured cell sheet.
