Expression of E. kanangrensis WntA. In all panels (except for panel H, where anterior is up), anterior is to the left. (A) Ventrolateral view. (B) Lateral view. Arrowhead indicates expression at the posterior rim of the head lobe. (C) Lateral view. Arrowhead indicates expression at the posterior rim of the head lobe. (D) Close-up of the anterior appendages. Asterisks mark tips of jaw, slime papilla and walking limb that are free from expression. Arrow indicates staining in the opening of the salivary gland. (E) Close-up of slime papilla and walking limb of an older embryo (compare with D). Arrowheads mark anterior and posterior border of expression in the limbs. Asterisks mark tips of jaw, slime papilla and walking limb that are free from expression. (F) Lateral view. (G) Close-up of frontal appendage and head lobe. Arrowheads mark anterior and posterior border of expression in the limbs. Asterisks mark tips of jaw, slime papilla and walking limb that are free from expression. (H) Ventral view. Note developing expression in the ventral nervous system. (A′) represents DAPI staining of the embryo of (A). fap, frontal appendage; hl, head lobe; j, jaw; L1, first walking-limb-bearing segment; sp, slime papilla; st, stage.
