ABSTRACT:
This invention relates to cell culture carriers consisting of a porous support, at least a part of which surface being coated with a water-insoluble polymer constituted by (meth)acrylic acid ester and/or (meth)acrylamides and a cross-linking agent, and having a positively chargeable chemical moiety on the polymer surface. The present carriers have enabled the high-density cell culture in any type of the culture methods.
