Figure Caption/Comments:

Fig. 5 Inhibition of gsc and foxA3 results in an upregulation of Wnt signaling at the dorsal margin. Compared to wild-type (A), embryos injected with wnt8a DNA (B) or inactivation of dkk1 by morpholino knock-down (C) results in deletion of anterior head. (D–F) Expression of wnt8a at shield stage in WT (D), gsc (E) and gsc/foxa3 (F) knock-down embryos. Arrowheads indicate the dorsal borders of wnt8a expression territory. (G–I) Expression of frzb at shield stage in WT (G), gsc (H) and gsc/foxa3 (I) knock-down embryos. (J, K) Expression of dkk1 at shield stage in WT (J) and gsc/foxa3 knock-down (K) embryos. Arrows indicate the dorsal most extent domain of dkk1 expression at the margin. (L) Expression of wnt8a at shield stage in an embryo injected with gsc RNA at the 32 cell stage in one ventro-lateral blastomere. Arrowheads indicate the limit of wnt8a expression at the gastrula margin. (A, B) 96 hpf, (C) 48 hpf, (D–L) shield stage. (A–C, G–I) Lateral view, (D–F) dorsal view, (J–L) animal pole view dorsal to the right.
