Fig. 6From: Enhancement of pacing function by HCN4 overexpression in human pluripotent stem cell-derived cardiomyocytesEvaluation of pacing function in vitro. A Macroscopic (left) and microscopic (right) images of co-culture with parent line iPSC-CMs. Scale bar is 200 µm. B Beating rates of EGFP-negative parent iPSC-CMs paced by EGFP-positive HCN4-overexpressing or non-overexpressing iPSC-CMs (n = 4 in each) (The data are shown as means ± standard deviation.)Back to article page
