Expression of E. kanangrensis Wnt9 and Wnt10 . (A-F) Expression of Wnt9. (G-J) Expression of Wnt10. Anterior is to the left. (A) Ventral view. Ubiquitous expression. (B) Lateral view. (C) Lateral view. (D) Ventrolateral view. (E) Ventral view. Anterior part of an embryo. (F) Ventral view. Close-up of the slime-papillae-bearing segment. Note the transverse stripe of expression (asterisk) that is level with the opening of the salivary gland (arrowhead) (cf. F′). (G) Lateral view. (H) Lateral view. (I) Ventral view, focused on the anterior of the embryo. (J) View of two slightly different angles of the same area of the embryo showing the slime-papillae-bearing segment. Note that the transverse stripe of expression is level with the posterior region of the salivary gland opening. (F′) and (I′) represent DAPI staining of the embryos of (F) and (I). fap, frontal appendage; hl, head lobe; j, jaw; L1, first walking-limb-bearing segment; pp, posterior pit region; sp, slime papilla; st, stage.
