The neural tube is the embryonic precursor to the central nervous system Neural crest cells (NCCs) are an excellent model to study how environmental factors modulate features such as cell multipotentiality and differentiation Despite many similarities between these rather distant species, there are also distinct differences in the contribution of the NC, particularly to the calvariae

the peripheral nervous system No obvious differences in pathway choice were noted for DiI-labeling at different lateral or medial positions of the trunk neural folds in neurulae, which contributed not only to It was previously thought that the rostral neural crest (cephalic crest) yielded mesenchymal tissue throughout the bodies of vertebrates, whereas the posterior portion (that is, the trunk
