Induction and Patterning of the Neural Crest, a Stem Cell-Like Precursor Population

Abstract

The neural crest is a multipotent precursor population which ulimately generates much of the peripheral nervous system, epidermal pigment cells, and a variety of mesectodermal derivatives. Individual multipotent neural crest cells are capable of some self-renewing divisions, and based upon this criteria can be considered stem cells. Considerable progress has been made in recent years toward understanding how this important population of progenitor cells is initially established in the early embryo, and how cell-intrinsic and non-cell-instristic factors mediate their subsequent lineage segregation and differentiation.
