A-SMA immunofluorescence analysis of cardiomyocytes. (A): Representative images of cardiac hypertrophy intervened by miR-26a-5p mimic and inhibitor, as shown by a-SMA immunofluorescence. The nucleus was stained with DAPI (blue). The scale bar shows 10 μm. (B): Cell surface area was measured using anti-SMA staining (green) under fluorescence microscopy. (*: p-value < 0.05; **: p-value < 0.01; ***: p-value < 0.001.)
