Fig. 4. Whole-cell patch-clamp experiments show decreased IKr current in edited hiPSC-derived CMs.

Fig. 4.

(A) Average whole-cell IKr current traces for WT (left) and edited (right) hiPSC-CMs show diminished IKr in edited cells. IKr is calculated as the subtraction of IK current by IK + E-4031 current. The voltage protocol is inset. (B) IKr current density measured at steady-state time points at 40 and −50 mV (as marked by red arrowheads in voltage inset). *P < 0.05; specifically at 40 mV, P = 0.017 and −50 mV, P = 0.036.
