The neural crest stem cells: control of neural crest cell fate and plasticity by endothelin-3.
How the considerable diversity of neural crest (NC)-derived cell types arises in the vertebrate embryo has long been a key question in developmental biology. The pluripotency and plasticity of differentiation of the NC cell population has been fully documented and it is well-established that environmental cues play an important role in patterning the NC derivatives throughout the body. Over the...
متن کاملNeural crest cell plasticity and its limits.
The neural crest (NC) yields pluripotent cells endowed with migratory properties. They give rise to neurons, glia, melanocytes and endocrine cells, and to diverse 'mesenchymal' derivatives. Experiments in avian embryos have revealed that the differentiation of the NC 'neural' precursors is strongly influenced by environmental cues. The reversibility of differentiated cells (such as melanocytes ...
متن کاملAnterior Hox Genes Interact with Components of the Neural Crest Specification Network to Induce Neural Crest Fates
Hox genes play a central role in neural crest (NC) patterning particularly in the cranial region of the body. Despite evidence that simultaneous loss of Hoxa1 and Hoxb1 function resulted in NC specification defects, the role of Hox genes in NC specification has remained unclear due to extended genetic redundancy among Hox genes. To circumvent this problem, we expressed anterior Hox genes in the...
متن کاملRegulative capacity of the cranial neural tube to form neural crest.
In avian embryos, cranial neural crest cells emigrate from the dorsal midline of the neural tube shortly after neural tube closure. Previous lineage analyses suggest that the neural crest is not a pre-segregated population of cells within the neural tube; instead, a single progenitor in the dorsal neural tube can contribute to neurons in both the central and the peripheral nervous systems (Bron...
متن کاملHoxb1 neural crest preferentially form glia of the PNS.
The vertebrate cranial neural crest cells give rise to many complex derivatives of the head, neck, and face, including neuronal and glial cells that act in concert for proper development of the anterior-peripheral nervous system. Several genes have been implicated in the processes of neural crest specification, migration, and differentiation; among these are the hox gene clusters. To determine ...
