Abstract

The neural crest is a multipotent and highly migratory cell type that contributes to many of the defining features of vertebrates, including the skeleton of the head and most of the peripheral nervous system. 150 years after the discovery of the neural crest, avian embryos remain one of the most important model organisms for studying neural crest development. In this review, we describe aspects of neural crest induction, migration and axial level differences, highlighting what is known about the underlying gene regulatory mechanisms. Past and emerging technologies continue to improve the resolution with which we can examine important questions of neural crest development, with modern avian molecular embryology continuing to make important contributions.
