Abstract

The neural crest is a transient population of multipotent progenitors arising at the lateral edge of the neural plate in vertebrate embryos. After delamination and migration from the neuroepithelium, these cells contribute to a diverse array of tissues including neurons, smooth muscle, craniofacial cartilage, bone cells, endocrine cells and pigment cells. Considerable progress in recent years has furthered our understanding at a molecular level of how this important group of cells is generated and how they are assigned to specific lineages. Here we review a number of recent studies supporting a role for Wnt signaling in neural crest induction, differentiation, and apoptosis. We also summarize the timing of expression of a number of Wnt ligands and receptors with respect to neural crest induction. BioEssays 25:317–325, 2003. © 2003 Wiley Periodicals, Inc.

## Abstract Embryonic stem (ES) cells have the potential to develop into various cell lineages including hemangioblasts (Flk1^+^), a common progenitor for hematopoietic and vascular endothelial cells. Previous studies indicate that Flk1^+^ cells, a marker for hemangioblast, can be derived from ES c

The neural crest is a multipotent precursor population which ultimately 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 cri

Signal transduction pathways are largely conserved throughout the animal kingdom. The repertoire of pathways is limited and each pathway is used in different intercellular signaling events during the development of a given animal. For example, Wnt signaling is recruited, sometimes redundantly with o
