<p>PURPOSE:To provide the subject material capable of culturing and recovering cells in simple processes without the contamination of impurities and without deteriorating the functions of the cells by coating the surface of a cell-adhesive substrate with a specific homo(co)polymer preferably in a specified pattern. CONSTITUTION:The surface of a cell-adhesive substrate such as a petri dish shape substrate prepared by subjecting modified glass, polystyrene, etc., if necessary, to an ozone treatment, etc., is coated with a homopolymer or copolymer [e.g. acrylamide homo(co)polymer] having a critical dissolution temperature of 0-80 deg.C in water preferably in a pattern such as a pattern having lines and spaces or a polka dot pattern in a total coverage degree of 5-90% to provide the objective material.</p> |
