..., the expression of LSox5 is maintained in cephalic crest derivatives, and it appears to be required for the development of the glial lineage, the Schwann cells and satellite glia in cranial ganglia. Misexpression of LSox5 in the cephalic neural tube activated RhoB expression throughout the dorsoventral axis...

... that Slug can induce the expression of rhoB and an increase in the number of HNK-1-positive migratory cells, indicating that it lies upstream of them in the genetic cascade of neural crest development. The increase in neural crest production after Slug overexpression was confined to the cranial region...

... in vivo was preceded by a partial or total reduction in the expression of cadherin-6B and rhoB but not in the expression of slug mRNA or protein. Altogether, these results suggest that a coordinated activity of Noggin and BMP4 in the dorsal neural tube triggers delamination of specified, slug -expressing...
