Expression of Pdu-Dll during caudal regeneration of Platynereis dumerilii [16 dpa (days post-amputation)]. In situ hybridizations, anterior is to the left in (a–f). a Ventral view of the regenerated posterior end. The red line marks the site of amputation. Regenerated tissues are to the right. b Expression is located at the base of and in the anal cirri (white arrows), ventral view (c, e) Pdu-Dll expression in the notopodia at the base of the dorsal cirri (black arrowheads) and in the proximal part of the dorsal cirri (black brackets) (d, f) Developing neuropodia show expression at the base of the ventral cirri (white arrowheads) and at the base of the parapodia (gray arrowheads). g–i Optical transverse sections of segments in different phases of maturation with focus on parapodia, ventral side down. Expression domains indicated in c–f are labeled accordingly, (ac) anal cirri, (dc) dorsal cirrus, (nep) neuropodium, (nop) notopodium, (pb) parapodial bud, (pp) parapodia, (vc) ventral cirrus. Scale bar equals 200 µm
