Pn-vasa mRNA in the juvenile worm. A Pn-vasa signal is strongly expressed in the older segments, I and II and becomes weaker towards the younger segments (Segment III-VIII). A’ Parapodia of (A) showing the strong hybridization signals in older segments I and II with the sense probe experiment B’. A ” Posterior end of (A) showing the more intense Pn-vasa signals in the pygidium (P) and another Pn-vasa signals detected in the anterior border of the pygidium (A”, arrows). (B”) Sense probe experiment. Pe, peristomium or Ce, cephalic segment
