Distinct iPS Cells Show Different Cardiac Differentiation Efficiency

Figure 5

Electrophysiological studies of cardiomyocytes (CM) derived from mouse embryonic stem (ES) cells, Nanog induced pluripotent stem (iPS) cells, and Fbx15-iPS cells. Representative action potentials of (a) ES cell-derived CM, (b) Nanog-iPS cell-derived CM, and (c) Fbx15-iPS cell-derived CM showing sinus node-like (top), fetal atrial-type (middle), and fetal ventricular-type (bottom) action potentials.
