Method for cryopreserving sheet-shaped cell culture

Provided is a method for cryopreserving a sheet-shaped cell culture.　The present invention pertains, inter alia , to a method for freezing a frozen sheet-shaped cell culture comprising: (1) a step for immersing, in a cryopreservation solution, a sheet-shaped cell culture supported on a mesh-shaped support body; (2) a step for removing cryopreservation solution that has adhered to the sheet-shaped cell culture, while keeping the sheet-shaped cell culture supported on the mesh-shaped support body; (3) a step for enclosing the sheet-shaped cell culture in a cold-resistant film, the upper surface and lower surface of the sheet-shaped cell culture being covered by the mesh-shaped support body; and (4) a step for freezing the sheet-shaped cell culture.
