Figure 5
Additional expressions of Platynereis neural genes during trunk neurogenesis. A, D, E-H are ventral views; B, C are lateral views (ventral on the left). Most of the images are ImageJ projections. Labels are as in Figure 1. E-H correspond to more internal views than those of Figure 4U-Y which are superficial views. See the main text for details. Arrows in E-H point to internal cells expressing neural bHLH genes and that may belong to the posterior growth zone [41,42].
