Document Type and Number:
WIPO Patent Application WO/2021/251417
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a composition for forming a biocompatible coating film, said composition comprising a block copolymer having a specific structure, a coating film using the same, a cell culture substrate using the same, a method for manufacturing a cell culture substrate, and a method for producing a cell aggregate. A composition for forming a biocompatible coating film, said composition comprising a block copolymer having unit structures represented by formulae (1) and (2) (in the formulae: R1 to R3, U1 and U2 independently represent each a hydrogen atom or an alkyl group having 1-5 carbon atoms; X1 and X2 represent an alkylene group having 1-5 carbon atoms; and n represents an integer of 1-10) and a solvent.
