Fate of the mammalian cranial neural crest
The vertebrate neural crest is a pluripotent cell population derived from the lateral ridges of the neural plate during early stages of embryogenesis. Neural crest cells disperse from the dorsal surface of the neural tube and migrate extensively through the embryo, giving rise to a wide variety of differentiated cell types (Romer, 1972; Noden, 1983; Tan and Morriss-Kay, 1986; Bronner-Fraser, 19...
متن کاملXenopus cadherin-11 restrains cranial neural crest migration and influences neural crest specification.
Cranial neural crest (CNC) cells migrate extensively, typically in a pattern of cell streams. In Xenopus, these cells express the adhesion molecule Xcadherin-11 (Xcad-11) as they begin to emigrate from the neural fold. In order to study the function of this molecule, we have overexpressed wild-type Xcad-11 as well as Xcad-11 mutants with cytoplasmic (deltacXcad-11) or extracellular (deltaeXcad-...
متن کاملEts-1 Confers Cranial Features on Neural Crest Delamination
Neural crest cells (NCC) have the particularity to invade the environment where they differentiate after separation from the neuroepithelium. This process, called delamination, is strikingly different between cranial and trunk NCCs. If signalings controlling slow trunk delamination start being deciphered, mechanisms leading to massive and rapid cranial outflow are poorly documented. Here, we sh...
متن کاملCranial neural crest migration: new rules for an old road.
The neural crest serve as an excellent model to better understand mechanisms of embryonic cell migration. Cell tracing studies have shown that cranial neural crest cells (CNCCs) emerge from the dorsal neural tube in a rostrocaudal manner and are spatially distributed along stereotypical, long distance migratory routes to precise targets in the head and branchial arches. Although the CNCC migrat...
متن کاملTemporal requirement of Hoxa2 in cranial neural crest skeletal morphogenesis.
Little is known about the spatiotemporal requirement of Hox gene patterning activity in vertebrates. In Hoxa2 mouse mutants, the hyoid skeleton is replaced by a duplicated set of mandibular and middle ear structures. Here, we show that Hoxa2 is selectively required in cranial neural crest cells (NCCs). Moreover, we used a Cre-ERT2 recombinase system to induce a temporally controlled Hoxa2 delet...
