Fig. 12From: Structure, phylogeny, and expression of the frizzled-related gene family in the lophotrochozoan annelid Platynereis dumerilii Expression of fz4 in larval stages (48 hpf to 5-day old) in Platynereis. a–d Anterior views of the head region with ventral side down. e–h Ventral views with anterior side up. Asterisks indicate the stomodeum. Black arrowheads indicate specific staining in brain. Gene expression analysis was performed with WMISH.
