Plate 8: The cross section of the posterior part of this neurula stage (35h pf, 18°C) again reveals a developmental gradient. Especially the cells of the endoderm and its derivatives, the mesoderm and the notochord, are less differentiated compared to the more anterior regions of the animal. Most notably the anläge of the notochord is not separated from the archenteron. In the dorsolateral mesoderm the medial and lateral cells are hardly differen- tiated (from Stach 1994, modified)..
