Patent ID: 7687251

Claim:
A method for producing a patterned cell culture substrate comprising: forming on a base material, a light shielding element containing a material which can shield ultraviolet rays or visible light, and a cell adhesive layer containing a photocatalyst and a material to which cells adhere, wherein the light shielding element is sandwiched between the base material and the cell adhesive layer, and wherein the cell adhesive material is decomposed or denatured by action of the photocatalyst upon irradiation with ultraviolet rays or visible light; irradiating the patterning substrate from the base material side to form a pattern consisting of: a cell adhesion inhibiting portion in which the cell adhesive material is decomposed or denatured, and a cell adhesion portion which is other than the cell adhesion inhibiting portion; and attaching or adhering a cell to the cell adhesion portion, wherein the cell is in a cell culture.
