Fig. 2. Asymmetric expression of Nodal pathway components is unaffected by the
fby mutation. (A,B,F,G) The lateral
plate mesoderm and (C-E,H-J) the dorsal diencephalon of 20-hpf
zebrafish embryos. All views are dorsal, except for frontal views in E and J.
Left-sided expression of the Nodal-related genes southpaw
(spaw; A,F) and cyclops (cyc; C,H), the Nodal
antagonist lefty1 (lft1; B,D,G,I), and of the downstream
Nodal effector pitx2 (E,J) was observed in both WT and fby
mutant embryos during somitogenesis. Scale bars: 25 µm.
