Facile cell sheet manipulation and transplantation by using in situ gelation method.

Cell sheets harvested from temperature-responsive cell culture dishes (TRDs) has attracted considerable attention as effective tools for reconstructing the lost functions of tissues and organs in the regenerative medicine field. However, because of their thinness, handling problems sometimes arise when transferring cell sheets from a TRD to a target surface. In this study, we developed a facile cell transfer method referred to as in situ gelation by using both gelatin hydrogel and a support membrane.
