FIG. 2.
Morphological changes induced by pG48R during zebrafish early embryonic development. The expression profile of pG48R is shown at the following stages: 14 (A and a), 16 (B and b), 18 (C and c), 20 (D and d), 22 (E and e), 24 (F and f), 26 (G and g), 28 (H and h), 30 (I and i), 32 (J and j), 34 (K and k) hpf, and 36 (L and l). Fluorescence (upper panels) and normal (lower panels) images of zebrafish embryos expressing the fusion gene were recorded continuously for 20 h after embryonic injection. The white arrow in panel H and the black arrow in panel h indicate the position of the dilated endocardium in the injected embryos. Embryos shown in panels F, f, G, g, H, I, K, k, and L are dorsal views. All others are lateral views. Bar, 250 μm for all panels.
