Specification of the neural crest occurs during gastrulation and requires Pax7
Article Abstract:
Neural crest induction is underway during gastrulation and well before proper neural plate appearance was reported and it was established that Pax7 as an early marker required for nuetral crest formation in avian embryos. Results indicated that neural crest specification initiated in the beginning than formerly assumed, independently of mesodermal and neural tissues, and Pax7 had a crucial function during the neural crest development.

Collinear activation of Hoxb genes during gastrulation is linked to mesoderm cell ingression
Article Abstract:
A demonstration that in the paraxial mesoderm, Hoxb genes are first activated in a temporal collinear fashion in precursors located in the epiblast lateral to the primitive streak is presented. Results suggest that collinear activation of Hoxb genes regulates the flux of cells from the epiblast to the streak and thus directly controls the establishment of the genes' characteristics nested expression domains in the somites.
