Neural crest cells are a temporary group of cells unique to vertebrates that arise from the embryonic ectoderm germ layer, and in turn form various cell lineages.
These cells originating from different positions along the anterior - posterior axis develop into various tissues. These regions of neural crest can be divided into four main functional domains, which include the cranial neural crest, trunk neural crest, vagal and sacral neural crest and caridiac neural crest.
Cranial neural crest migrates dorsolaterally to form the craniaomesenchyme that differentiates into various cranial ganglia and craniofacial cartilages and bones.
Trunk neural crest
They gives rise to two populations of cells. One group of cells fated to became melanocytes migrates dorsolaterally into the ectoderm towards the ventral midline. A second group of cells migrates ventrolaterally through the anterior portion of each sclerotome. The cells that stay in the sclerotome form the dorsal root ganglia, whereas those that continue more ventrally form the sympathetic ganglia, adrenal medulla and the nerves surrounding aorta.
Vagal and sacral neural crest
The vagal and sacral neural crest cells develop into the ganglia of the enteric nervous system and the parasympathetic ganglia.
Cardiac neural crest
The cardiac neural crest develops into melanocytes, cartilage, connective tissue and neurons of some pharyngeal arches.
