dorsal portion of the neural tube (the primitive nervous system) that produces undifferentiated pigment cells and the peripheral nervous system.
Group of embryonic cells derived from the roof of the neural tube that migrate to different locations and give rise to various types of adult cells, including nerve cells in peripheral ganglia, chromaffin cells, melanocytes, and Schwann cells.
A vertebrate-specific migratory cell type that derives from the dorsal-most aspect of the neural tube and contributes to many tissues, including the peripheral nervous system and cranium.
A specific cellular band present during very early development that gives origin to nerve cells and many other structures.
cell region at edge of neural plate, then atop the neural folds, that remains outside and initially dorsal to the neural tube when it forms. These paired dorsal lateral streaks of cells migrate throughout the embryo and can differentiate into many different cell types(= pluripotential). Those that remain on the dorsal neural tube form the sensory spinal ganglia (DRG). Neural crest cells also migrate into the somites. (More? Neural Crest Notes)
Formed from neural plate cells that break away as the neural tube is being formed in the vertebrate embryo.
specialized neuroectoderm cells that contribute to bone formation of the cranial vault and portions of the jaw and lower face. Go to Bone Formation page.
neuralis - nerve]. A group of cells found at the edges of the neural plate and lying above the neural tube after its formation. They migrate throughout the embryo to form ganglia, pigment cells, parts of gill arches, etc.
populations of mesodermal cells that separate from the neural tube as the neural tube pinches off from the surface ectoderm. It is fated to differentiate into visceral skeletal elements, nerve ganglia and, in combination with mesodermal cells, a variety of mesenchymal derivatives.
The portion of the neural plate and neural groove containing cells that give rise to the peripheral nervous system. At the neural groove stage, the neural crest occupies the lateral margins of the groove. At the neural tube stage, the neural crest separates from the neural tube.
The neural crest, a component of the ectoderm, is found in between the neural tube and the epidermis of an embryo.
