Figure 3.ZLN005 improved cardiac structural maturation. (A) Representative immunostaining of α-ACTININ (red) and Hoechst 33342 (blue) in control- or ZLN005-treated hESC-CMs. Scale bar, 20μm and 5μm. (B and C) ZLN005-treated hESC-CMs showed significant increase in sarcomere length and a decrease in circularity index compared to control. n=20-60 cells per condition. (D) qRT-PCR analysis of cardiac structural maturation markers in control and ZLN005-treated hESC-CMs (n=6).
