title: Restriction of neurogenic ability during neural crest cell differentiation.
abstract: Multipotent neural crest cells undergo developmental restrictions during embryogenesis and eventually give rise to the neurons and glia of the peripheral nervous system, melanocytes, and pheochromocytes. To understand how neuronal potential is restricted to a subpopulation of crest-derived cells, we have utilized sensitive markers of early neuronal differentiation to assess neurogenesis in crest-derived cell populations subjected to defined experimental conditions in vitro and in vivo. We describe environmental conditions that either (a) result in the irreversible loss of neurogenic potential over a characteristic time course or (b) maintain neurogenic potential among neural crest cells.
