Fig. 3

Elongation of dorsal mesendodermal cell populations, dorsal translocation, and fate-mapping analyses of lateral cell groups in WT, din, and sbn mutants. (A) Elongation of labeled mesendodermal cell populations is reduced in din mutant gastrulae by the end of the gastrula period. (B) Assaying dorsal translocation of labeled lateral marginal cells indicates that convergence movements in both sbn and din mutants become impaired after midgastrulation. Fate-map analysis of lateral marginal cells in (C) WT, (D) din, and (E) sbn embryos at early segmentation; the resulting labeled lateral cell array is seen in red (FL). The anterior boundary of the labeled cell array is marked by an arrowhead; in WT, the array extends around the embryo into the head mesoderm and its anterior boundary is not visible, denoted by an arrow. paraxial protocadherin (papc) expression is shown in brown. s, somites; n, notochord.
