ZFIN Phenotype Statement: pharyngeal arch neural crest cell dlx2a expression decreased amount, abnormal

Phenotype:	pharyngeal arch neural crest cell dlx2a expression decreased amount, abnormal
Note:	This phenotype statement describes a gene expression or antibody labeling pattern. Anatomy terms are combined with a gene or antibody and phenotype quality.

EXPRESSION ANATOMY:

Name:	pharyngeal arch
Synonyms:	pharyngeal arches
Definition:	One of a series of paired bony or cartilaginous arches that develop along the lateral walls of the foregut. The pharyngeal arches have developmental contributions from endoderm, mesoderm, and neural crest cells and are separated by anterior lateral endoderm out-pockets known as pharyngeal pouches. There are seven pharyngeal arches.

Name:	neural crest cell
Synonyms:	neural crest cells
Definition:	A cell of the neural crest. The neural crest is a strip of specialized ectoderm, the neural plate border, which flanks each side of the embryonic neural plate. Neural crest cells are multipotent. Premigratory neural crest cells are found at the neural plate boarder, some of which will undergo ectomesenchymal transition and delamination to form migratory neural crest cells. Most of the cranial and all of the spinal sensory ganglion cells arise by differentiation of neural crest cells.
