Expression patterns of Pdu-Hes10 and their schematic representations in Platynereis larvae and during posterior elongation (PE). Whole-mount in situ hybridization (WMISH) for the different stages indicated on each panel is shown. Pdu-Hes10 is expressed in several brain cells from 33 to 72 h post fertilization (hpf), as well as in the stomodeum, disparate ectodermal cells (48 hpf) and gut cells (72 hpf). Pdu-Hes10 has a salt and pepper expression pattern in the ventral nerve cord (VNC), plus an expression in disparate unknown cells of the forming parapodia, possibly corresponding to sensory or peripheral nervous system cells. Panels are ventral views (anterior is up) for the larvae and during PE.
