摘要

The present invention has as its object to find out new conditions that make it possible to induce cell death of non-cardiomyocytes or undifferentiated stem cells more completely and to select cardiomyocytes only. In order to achieve this object, there are provided in the present application: a cell culture medium for use in inducing cell death of undifferentiated stem cells, wherein the cell culture medium is free of glutamine in the amino acid profile; and also a method for inducing cell death of non-cardiomyocytes by performing cell culture in said cell culture medium. Further provided in this application are: a cell culture medium for use in selecting cardiomyocytes, wherein the cell culture medium is supplemented with lactate, pyruvate or a fatty acid, free of sugar, and free of glutamine in the amino acid profile; and also a method for selecting cardiomyocytes by culturing a mixture of cardiomyocytes and non-cardiomyocytes in said cell culture medium.
