Coinjection of transferrin-a or TfR1a cRNA rescues anemia in transferrin-a morphants. O-dianisidine staining for hemoglobin at 48 hpf comparing (A) uninjected WT, (B) overexpression of transferrin-a cRNA, (C) morpholino knockdown of transferrin-a, (D) coinjection of transferrin-a cRNA with transferrin-a morpholino, (E) coinjection of TfR1a cRNA with transferrin-a morpholino. The scale bar represents 200 μm.
