The neural crest (NC) is often a multipotent cell population which arises inside the dorsal neural plate/non-neural ectoderm border area for the duration of vertebrate embryogenesis. Studies utilising chick and amphibian embryos have indicated that diverse levels of BMP, WNT and FGF signals, emanating in the mesoderm/non-neural ectoderm, orchestrate NC induction and specification (Stuhlmiller and Garci -Castro, 2012). This happens through the action, first of neural plate border-specific transcription elements like PAX3/7, MSX and ZIC members of the family, and then via definitive NC-specifiers (e.g. SOX9/10) (Simoes-Costa and Bronner, 2015).
