Ct-eve1 and Ct-eve2 expression in the posterior growth zone of juveniles. All panels show the posterior end of juveniles. A and B are ventral (vent) views and C and D are lateral (lat) views with ventral down. A bracket denotes the PGZ. (A) Ct-eve1 is expressed in the ectoderm and mesoderm of the PGZ and in the ganglia of the ventral nerve cord (VNC). (B) Ct-eve2 is expressed in the PGZ and weakly in the ganglia of the VNC. (C) Ct-eve1 expression in the PGZ is more prominent on the ventral side than on the dorsal side (bracket). (D) In addition to PGZ expression in the ectoderm and mesoderm (bracket), Ct-eve2 is expressed in the anus (arrow). gn: ganglion; lat: lateral; vent: ventral.
