Fig. 2
vegfaa expression during adult zebrafish heart regeneration. (A and B) Colocalization of vegfaa:EGFP and kdrl:DsRed expression in hearts without injury and at 3 dpa. (C and D) vegfaa:EGFP expression in an uninjured heart and a heart 7 d post CM ablation (dpi). (E and F) vegfaa:EGFP expression in an uninjured heart and a heart after 14 d (dpi) of nrg1 overexpression. Arrows indicate EGFP+ endocardial cells. Boxes correspond to the region magnified in adjacent panels. [Scale bars: A, C, and E, 100 μm (Left) and 25 μm (Right); scale bars correspond to B, D, and F, respectively.]
