Expression of fz1/2/7, fz9/10, fz5/8, sfrp1/2/5, and fzCRD-1 in early (24 hpf) and late (48 hpf) trochopore and nectochaete (3-day old) Platynereis larvae. Gene expression analysis was performed with WMISH. Probes are listed on the left of each row. Stages and orientations are listed at the top of each column. Refer to the “Results” for details on the expression patterns. Dotted line in B, H, N, T, and Z indicate the location of the ciliated prototroch. Asterisk in ventral views indicates the stomodeum. Black arrowheads indicate the following: ventral midline expression (J, K, V and W), fz5/8 expression in chaetal sacs (P), sfrp1/2/5 expression in early forming segments (T), fzCRD-1 expression in the ring canal (Z), and bilaterally symmetric domains in the trunk (BB)
