Imaging neural crest cell dynamics during formation of dorsal root ganglia and sympathetic ganglia.
The neural crest is a migratory population of cells that produces many diverse structures within the embryo. Trunk neural crest cells give rise to such structures as the dorsal root ganglia (DRG) and sympathetic ganglia (SG), which form in a metameric pattern along the anterior-posterior axis of the embryo. While static analyses have provided invaluable information concerning the development of...
متن کاملCXCR4 controls ventral migration of sympathetic precursor cells.
The molecular mechanisms that sort migrating neural crest cells (NCCs) along a shared pathway into two functionally discrete structures, the dorsal root ganglia and sympathetic ganglia (SGs), are unknown. We report here that this patterning is attributable in part to differential expression of the chemokine receptor, CXCR4. We show that (1) a distinct subset of ventrally migrating NCCs express ...
متن کاملChicken protocadherin-1 functions to localize neural crest cells to the dorsal root ganglia during PNS formation
In vertebrate embryos, neural crest cells emerge from the dorsal neural tube and migrate along well defined pathways to form a wide diversity of tissues, including the majority of the peripheral nervous system (PNS). Members of the cadherin family of cell adhesion molecules play key roles during the initiation of migration, mediating the delamination of cells from the neural tube. However, a ro...
متن کاملDisruption of CXCR4 signaling in pharyngeal neural crest cells causes DiGeorge syndrome-like malformations.
DiGeorge syndrome (DGS) is a congenital disease causing cardiac outflow tract anomalies, craniofacial dysmorphogenesis, thymus hypoplasia, and mental disorders. It results from defective development of neural crest cells (NCs) that colonize the pharyngeal arches and contribute to lower jaw, neck and heart tissues. Although TBX1 has been identified as the main gene accounting for the defects obs...
متن کاملA novel spalt gene expressed in branchial arches affects the ability of cranial neural crest cells to populate sensory ganglia.
Cranial neural crest cells differentiate into diverse derivatives including neurons and glia of the cranial ganglia, and cartilage and bone of the facial skeleton. Here, we explore the function of a novel transcription factor of the spalt family that might be involved in early cell-lineage decisions of the avian neural crest. The chicken spalt4 gene (csal4) is expressed in the neural tube, migr...
