Cell culture support and manufacture thereof

摘要

An object of the present invention is to provide a cell culture support making the detachment of a cell sheet easy as well as enabling the formation of a uniform cell sheet. The present invention relates to a method for manufacturing a cell culture support having a temperature responsive polymer immobilized onto the surface thereof via covalent bonding, the method including a coating step in which a composition including a monomer that can form the polymer by polymerization by radiation irradiation, an organic solvent and, in some cases, a prepolymer formed by polymerization of the monomer is coated onto the substrate having a surface containing a material which can be covalently bonded to the temperature responsive polymer by radiation irradiation to form a film on the surface of the substrate, a radiation irradiation step in which a polymerization reaction and a binding reaction between the substrate surface and the temperature responsive polymer are allowed to proceed by irradiating radiation to the film, and a drying step to dry the film.
