Direct contact co-culture is required for non-myocyte regulation of iPSC-CM electrophysiology
(A) Experimental outline showing combined encapsulation of all cells (direct contact) or separation of each cell type (indirect contact).
(B) Quantification of iPSC-CM spontaneous beating rate.
(C) iPSC-CM calcium transient amplitude.
(D) iPSC-CM calcium transient time to peak.
(E) iPSC-CM calcium transient time to 80% decay.
Data are shown as mean ± SEM. Each datapoint represents 1 dish, containing average of 3 cells, 3 beats/cell, N = 3.
