(E) Representative paced (0.8 Hz) impedance recordings of hiPSC-CMs cultured in MMb, MMs, or MMc formulations ± FA and CD from day 20 to day 32.
(F) Pulse width at 50% measured from impedance recordings of hiPSC-CMs cultured in MMb, MMs, or MMc formulations ± FA and CD (n = 4).
(G) OCR of hiPSC-CMs cultured in MMb, MMs, or MMc formulations ± FA and CD from day 20 to day 33 (n = 5).

Each data point shape indicates a different hiPSC line. Data are presented as mean ± SEM. n = biological replicates, ANOVA, *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.005, ****p ≤ 0.0001. See also Figure S5.
