  1. Our results indicate that at least some neural crest cells are multipotent before their departure from the neural tube. (Web site)

Neural Crest Cell Fate

  1. Finally, caudal to the hindlimbs, much of the neural tube appeared to adopt a dorsal, likely neural crest cell fate. (Web site)

  1. Schwann cells that form neural sheaths of some nerve fibers and of peripheral nerves form from neural crest cells and cells from the mantle.

Cadherins

  1. However, a role for cadherins in the sorting and re-aggregation of the neural crest to form the PNS has not been established.

  1. Origin of the avian neural crest. (Web site)

Neurulation

  1. Neural crest cells quickly migrate during or shortly after neurulation, an embryological event marked by neural tube closure.

Protochordates

  1. The neural crest itself has been believed to distinguish vertebrates from protochordates and invertebrates.

Emt

  1. Migration of neural crest cells is an example of EMT, with both intra- and extra-cellular cell adhesion molecules important in its initiation.
  2. Surprisingly, we discovered that when an EMT was preceded by a mitotic event, the plane of cytokinesis does not predict neural crest cell fate.

Premigratory Neural Crest Cells

  1. In addition, we consider the role of temporal restriction in the developmental potential of premigratory neural crest cells. (Web site)
  2. Wnt1 regulatory sequences direct expression in premigratory neural crest cells derived from the dorsal CNS and demarcate the presumptive midbrain (9). (Web site)

Neural Crest Cells Form

  1. If everything was rigidly preprogrammed when neural crest cells form in the neural tube, you certainly wouldn’t have the same flexibility.

Neural Crest Stem Cells

  1. Neural crest stem cells give rise to a number of different tissues including the peripheral nervous system.
  2. Isolation and directed differentiation of neural crest stem cells derived from human embryonic stem cells. (Web site)
  3. Here, we show that the small HLH protein Id3 is a Myc target that plays an essential role in the formation and maintenance of neural crest stem cells. (Web site)

Avian Neural Crest Cells

  1. Erickson, C. A. and Goins, T. L. 1995. Avian neural crest cells can migrate in the dorsolateral path only if they are specified as melanocytes. (Web site)

Neural Crest Derivatives

  1. In addition the development of neural crest derivatives such as dorsal root ganglion was impaired.
  2. No neural crest cells exited from the ventral neural tube but no deficiency in neural crest derivatives was recorded. (Web site)

Neural Crest Cell Migration

  1. Expression of cell adhesion molecules during initiation and cessation of neural crest cell migration.

Genome Duplications

  1. Alternatively, these observations suggest that delamination of the neural crest evolved after the genome duplications. (Web site)
  2. The key factor to determine whether the primitive neural crest delaminated prior to the genome duplications may be the lamprey neural crest. (Web site)

Cranial Neural Crest

  1. Whereas hox gene expression has been closely studied in cranial neural crest, little is known about the role of hox genes in trunk neural crest.
  2. There is still controversy regarding the embryonic lineage of the parietal bone – whether it is mesoderm or cranial neural crest. (Web site)
  3. Knight RD, Schilling TF: Cranial neural crest and development of the head skeleton.

Neural Crest Development

  1. We found that many, but not all, of the transcription factors were involved in neural crest development before the genome duplications. (Web site)

Cranial Neural Crest Cells

  1. Twist function is required for the morphogenesis of the cephalic neural tube and the differentiation of the cranial neural crest cells in the mouse embryo. (Web site)
  2. By that I mean, cranial neural crest cells can be influenced by molecular factors during their migration to the pharyngeal arches.

  1. Migrating neural crest cells (b) Neural crest cells migrate to distant sites in the embryo.

Interesting

  1. In this sense, it is interesting to determine how the delamination of the lamprey neural crest is regulated. (Web site)
  2. It will be interesting to test to what extent the neural crest cells can pathfind when the protrusive activity of the filopodia is modulated. (Web site)

Components

  1. The medium can also be used free of serum and contains components which permit the growth and self-renewal of neural crest stem cells. (Web site)

Defects

  1. In mammals a role of RA during development of the branchial region was long ascribed to defects in the migration of the neural crest cells.
  2. These defects appear to be the result of decreased proliferation and increased apoptosis of neural crest and neural crest-derived cell populations. (Web site)
  3. We initially examined Snai1-cko embryos for defects in neural crest cell formation and delamination. (Web site)

Features

  1. Recent work in protochordates suggests the first chordates possessed migratory neural tube cells with some features of neural crest cells. (Web site)

  1. In early development, as the nerve cord [dorsal hollow nerve chord] is forming, neural crest cells leave the nerve cord and move through the body.

  1. The neural crest is a transient population of cells that migrate away from the dorsal neural tube in the vertebrate embryo.
