Expression of E. kanangrensis Wnt16. Anterior is to the left. (A) Ventral view. Arrowhead indicates expression in the posterior pit region. (B) Lateral view. Arrow indicates expression posterior to the eye groove. (C) Ventral view. Anterior part of an embryo. (D) Ventral view. Anterior part of an embryo. (E) Close-up of a slime papillae-bearing segment. Note that the anterior border of the segmental stripe is level with the opening of the salivary gland (arrow). (F) Lateral view. Note the segmental stripes extending into tissue dorsal to the limbs. (G) Embryo of (F), ventral view. (A′), (B′) and (F′) represent DAPI staining of the embryos of (A), (B) and (F). e, eye groove; fap, frontal appendage; hl, head lobe; j, jaw; L1, first walking-limb-bearing segment; sp, slime papilla; st, stage.
