Fig. 1. syn4 is expressed in the migrating NC. (A-L) Lateral
views of zebrafish (A-F) and Xenopus (G-L) embryos. Anterior is to
the left. (A,D) 12- to 14-somite embryo. (B,E) 20-somite embryo; (C,F) higher
magnification of the trunk region in B,E. (A-C) syn4 expression; (D)
sox10 expression; (E,F) crestin expression. Note that the
expression of syn4 in the migrating NC cannot be distinguished from
the expression of the NC markers. (G,J) Stage 26 embryo. (H,K) Stage 30
embryo. (I,L) Cephalic region of a stage 35 embryo. (G-I) syn4
expression. (J) twist expression. (K,L) fli expression. Note
the expression of syn4 in the migrating cephalic NC.
