Ct-neuroD is expressed in subsurface cells within the developing CNS. ao Ct-neuroD transcripts were detected in stage 3–6 animals using WMISH. Images are to the same scale as in Figs. 2 and 3. Arrowheads in (b) point to lateral patches of Ct-neuroD + cells in the trunk. White arrowhead in (c) points to a single Ct-neuroD + cell near the mouth opening. The black arrowheads in (c) and (f) indicate expression in the pygidium. Arrows in (e) point to a few Ct-neuroD + cells posterior to the mouth and in the ventral ectoderm. Black arrowheads in (m)–(o) indicate single Ct-neuroD + cells in the epidermis of the episphere. Arrowheads in panels (n) and (o) point to expression in the foregut. In each panel, the stage of the animal is indicated in the lower left, and the view is indicated in the lower right (lat lateral, vlat ventrolateral, vent ventral, ant anterior). In all lateral and ventrolateral views, anterior is to the left and ventral down; in all ventral views, anterior is to the left; in all anterior views, ventral is down. Panel (i) is a cropped view of the head. An asterisk marks the position of the mouth, and the prototroch (pt) and telotroch (tt) are labeled with dashes. STBP, stage 3 blastopore
