Abstract
The problem to be solved by the present invention is to provide a cultured cell sheet that expresses phenotypes of the chondroid tissue. The problems can be solved by producing the cultured cell sheet in which cells are cultured on a surface of a cell cultureware 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; bringing the cultured cell sheet in close contact with the carrier; and detaching the cultured cell sheet together with the carrier.
