Proliferation of human induced pluripotent stem (iPS) cell-derived cardiomyocytes in our study. The proliferation rates of non-cryopreserved cells (Control and/or pre-SC procedure) and cryopreserved cells (SC procedure or CSC procedure) were determined from growth curves generated by counting cells using an electric cell counter (Z1 Cell and Particle Counter; Beckman Coulter Inc, Fullerton, California, USA) at 0, 3, 5, 7, 9, 11, 13 and 15 days of culture.
