Cell culture substrate having a structural unit derived from furfuryl (meth) acrylate

A cell culture substrate comprising a coating layer on at least one side of a polymer substrate,

• wherein the coating layer comprises a copolymer having a weight average molecular weight from 50,000 to 800,000 and consisting of at least 60% by mole and no more than 90% by mole of a structural unit (1) and at least 10% by mole and no more than 40% by mole of a structural unit (2),
• wherein the structural unit (1) is derived from a furfuryl acrylate monomer of Formula (1):
• wherein, R1 represents a hydrogen atom or a methyl group and R2 represents a group represented by the following Formula (1-1) or the following Formula (1-2):
• wherein, R3 represents an alkylene group having 1 to 3 carbon atoms, and
• wherein the structural unit (2) is derived from an ethylenically unsaturated monomer comprising an acryloyl or meth acryloyl group and a hydroxy group.
