Inhibition of H₂S synthase with PAG impedes CM proliferation. (a–d) Representative images and related statistical results of CM mitosis and cytokinesis, as analyzed by pH3, Ki67, and Aurora B staining. Actinin was used to label CMs, and DAPI was used to label nuclei. Scale bar =50 μm. Vehicle: ; PAG: . (a, e) Cell size was measured by WGA staining. Actinin was used to label CMs, and DAPI was used to label nuclei. Scale . Vehicle: ; PAG: . The data are presented as the . and by Student’s -test.
