Abstract

The present invention is to provide a cell culture substrate including a block polymer including a segment having a lower critical solution temperature and a hydrophobic segment, the cell culture substrate further including an adhesive matrix, in which the adhesive matrix is an extracellular matrix and/or an adhesive synthetic matrix. Furthermore, the invention is to provide a cell culture substrate in which the extracellular matrix is at least one selected from laminin, fibronectin, vitronectin, cadherin, and fragments thereof, and/or the adhesive synthetic matrix is poly[2-(methacryloyloxy)ethyl dimethyl-(3-sulfopropyl) ammonium hydroxide] or an oligopeptide-carrying polymer.
