Cardiac injury triggers a localized increase in tbx20 expression. (A–H) Representative images of ISH for tbx20 on the heart sections of uninjured (A,B) and injured ventricles and atriums at different time points as indicated (C–H). Red arrowheads indicate atrial epicardium. (I,J) Confocal images of uninjured (I) and 7 dpa (J) heart sections from Tg(tbx20:moxGFP) zebrafish immunostained for GFP and α-actinin (red). DAPI marks nuclei. Boxed areas are magnified on the right panels. Dashed lines in (J) demarcate amputation planes. Scale bar: 100 μm (A–J); 20 μm (inset images).
