Ct-pros is expressed in single cells throughout the ectoderm and developing CNS. ar Ct-pros transcripts were detected in stage 3–6 animals using WMISH. Images are to the same scale as in Figs. 2 and 3. Arrowheads in (a) indicate Ct-pros + cells in the animal pole. Arrowheads in (b) and (c) indicate surface Ct-pros + cells within the anterior ectoderm. The arrow in (d) points to expression in single ectodermal cells in the peristomium. The arrow in (h) denotes a few lateral Ct-pros + ectodermal cells just posterior to the peristomium. Black arrowheads in panels (k), (l), (o), (p), and (r) point to expression in the developing VNC. The line in panel (p) denotes the ventral midline. The white arrowhead in (r) points to expression in the rectum. 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; and in all anterior views, ventral is down. Panels (j) and (n) are cropped images of the head. An asterisk marks the position of the mouth, and the prototroch (pt) and telotroch (tt) are labeled with dashes. In panel G, dashes mark prototroch and telotroch, respectively, from left to right. ST3epi, stage 3 epiboly; STBPclg, stage 3 blastopore closing; ST3mo, stage 3 mouth
