Provided is a temperature-responsive cell culture substrate. A non-crosslinked temperature-responsive polymer having a molecular weight between 10,000 and 150,000 is immobilized on the substrate surface with a density of 0.02 to 0.3 molecular chain per square nanometer. Using the provided temperature-responsive cell culture substrate, cells obtained from various tissues can be efficiently cultured. This culturing method makes it possible to efficiently peel off a cell sheet by just changing the temperature, without causing damage.
本发明提供了一种温度响应型细胞培养基底。基底表面固定了分子量在 10,000 到 150,000 之间的非交联温度响应聚合物,其密度为每平方毫米 0.02 到 0.3 个分子链。使用所提供的温度响应型细胞培养基底,可以有效地培养从各种组织中获得的细胞。这种培养方法只需改变温度,就能有效地剥离细胞膜,而不会造成损伤。
