LEN is activated in the endocardium during ventricle regeneration. (A) Schematic diagrams of the transgenic constructs and ventricular ablation process of Tg(vmhc:mCherry-NTR; LEN-P0.8:EGFP) fish. (B) Confocal optical section image showed enhancer-directed fluorescence (green) in the endocardium of ablated Tg(vmhc:mCherry-NTR; LEN-P0.8:EGFP) hearts at 24 hpt. Red, MHC immunostaining by MF20. A, atrium; AVC, atrioventricular canal; MHC, myosin heavy chain; V, ventricle. (C?L) Confocal stack projections showed enhancer-directed fluorescence (green) dramatically increased in ablated hearts of Tg(vmhc:mCherry-NTR; LEN-P0.8:EGFP) fish compared to control hearts. (M?V) Whole-mount in situ hybridizations showed dynamic egfp expression in ablated hearts of Tg(vmhc:mCherry-NTR; LEN-P0.8:EGFP) compared to control hearts. Scale bars, (B?L) 50 ?m, (M?V) 25 ?m. Dashed lines outline the hearts. Numbers indicate the ratio of representative staining observed. dpf, days post fertilization; hpt, hours post treatment. |
