Susceptibility to Ventricular Arrhythmias Resulting from Mutations in FKBP1B, PXDNL, and SCN9A Evaluated in hiPSC Cardiomyocytes

Figure 4

Line scans recorded from WT, MMRL 1239, and MMRL1126 hiPSC-CMs showing spontaneous Ca2+ transients in all hiPSC-CMs. However, fluorescence intensity was much lower in MMRL 1126, and spontaneous activity was episodic in nature.
