“…This property leads to different expression profiles in ion channels and sarcomeric proteins, such as less organized sarcomeric structures and calcium‐handling machinery. 122 However, multiple efforts to overcome this limitation have been used recently, 123 , 124 , 125 , 126 , 127 , 128 , 129 , 130 , 131 , 132 , 133 , 134 , 135 , 136 , 137 , 138 , 139 , 140 , 141 including biochemical stimulation, electrical stimulation, mechanical stimulation, surface topography, substrate stiffness modification, 3D culture, long‐term culture of hiPSC‐CMs, and extracellular matrix culture (Table 4 ). All of these methods have been reported to improve hiPSC‐CM maturation.…”
