DAB-enchanced Perl stain for ferric iron at 52 hpf in (A,B) uninjected WT, (C,D) transferrin-a cRNA overexpression, (E,F) morpholino knockdown of transferrin-a, (G,H) coinjection of transferrin-a cRNA with transferrin-a morpholino. Red arrow indicates the proctodeum. Blue arrow indicates the somites. The scale bar represents 200 μm.
