The present invention addresses the problem of finding new conditions that make it possible to more completely induce cell death in non-myocardial cells or in undifferentiated stem cells and to select only myocardial cells. In order to solve such a problem, the present application: provides a cell culture fluid that is used to cause cell death in undifferentiated stem cells, wherein glutamine is not contained in the amino acid composition; and further provides is a method for inducing cell death in non-myocardial cells by performing culturing in the cell culture fluid. The present application further provides a cell culture fluid that is used to selectively select myocardial cells, in which lactic acid, pyruvic acid, or fatty acid is added, sugar is not contained, and glutamine is not contained in the amino acid composition. Further provided is a method to selectively select myocardial cells by culturing a mixture of myocardial cells and non-myocardial cells in said cell culture fluid. |
