Fig. 2 NLCAM mRNA is widespread during the gastrulation phase. (A and B). Low level signal in 128-cell and sphere stage, in lateral view. (C–F) Shield (C and D) and 80% epiboly (E and F) embryos in lateral (C), dorsal (E) and animal pole (D and F; shield to the right) view, showing widespread expression but reduction in the midline (arrowheads). (G–J) A single bud-stage embryo viewed in successive rostro-caudal ∼90 ° rotations: A (anterior); P (posterior); D (dorsal); V (ventral); L (left); R (right). Note the elliptical head region (G) and the posterior adaxial stripes (H and I, arrowheads). These are represented in cartoon form in (G′–J′). Blue indicates regions of higher signal compared to the gastrulating embryo and white, the blastopore.
