Figure 4

Expression of E. kanangrensis Wnt2 . In all panels except (F) (anterior up), anterior is to the left. (A) Ventral view. Red double-arrow marks the anterior border of expression. Red arrow marks posterior border of expression. (B) Lateral view. Arrow points to expression in the tip of the frontal appendage. (C) Ventral view of embryo of (B). (D) Ventral view of the anterior of an embryo. (E) Lateral view. Arrowheads indicate dot-like expression posterior to the base of the frontal appendages. (F) Dorsal view. Embryo of (E). Arrowheads as in E. (A′), (B′) and (E′) represent DAPI staining of the embryos of (A), (B) and (E). fap, frontal appendage; hl, head lobe; j, jaw; L1, first walking-limb-bearing segment; pp, posterior pit region; sp, slime papilla; st, stage.
