Abstract: A method for producing a three-dimensional cell structure includes preparing a mixture of a cationic substance, an extracellular matrix component, a polyelectrolyte, and a cell population including endothelial cells and mouse-derived stromal cells, which exclude mouse-derived endothelial cells, collecting a cell aggregate from the mixture, and culturing a collected cell aggregate to obtain a three-dimensional cell structure.
