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.

摘要： A cell culture support is first prepared that is coated on a surface with a polymer the hydration force of which changes in a temperature range of 0-80° C.; cancer cells are then cultivated on the support in a temperature region where the polymer has weak hydration force; thereafter, the culture solution is adjusted to a temperature at which the polymer has a stronger hydration force, whereby the cultured cancer cells are detached; the detached cancer cells are then transplanted to a specified site of an animal on which transplantation is to be performed; this method is an efficient way of cancer cells transplantation.
