摘要:
The present invention provides a method for swiftly producing a layered cell sheet that is non-invasively obtained and is utilizable for transplantation, etc., the method including (1) a step of applying a centrifugal force to a first cell sheet on a temperature-responsive culture surface for a predetermined time in a temperature range from a lower critical solution temperature of the temperature-responsive culture surface to 45° C., (2) a step of further placing a second cell sheet on the first cell sheet, and (3) a step of applying a centrifugal force to the first cell sheet and the second cell sheet on the temperature-responsive culture surface for a predetermined time in the temperature range from the lower critical solution temperature to 45° C.; and also provides a layered cell sheet obtained by the method.
