Semaphorin signaling guides cranial neural crest cell migration in zebrafish.
Cranial neural crest cells (NCCs) migrate into the pharyngeal arches in three primary streams separated by two cranial neural crest (NC)-free zones. Multiple tissues have been implicated in the guidance of cranial NCC migration; however, the signals provided by these tissues have remained elusive. We investigate the function of semaphorins (semas) and their receptors, neuropilins (nrps), in cra...
متن کاملCranial neural crest cell contribution to craniofacial formation, pathology, and future directions in tissue engineering.
This review provides an overview of the state and future directions of development and pathology in the craniofacial complex in the context of Cranial Neural Crest Cells (CNCC). CNCC are a multipotent cell population that is largely responsible for forming the vertebrate head. We focus on findings that have increased the knowledge of gene regulatory networks and molecular mechanisms governing C...
متن کاملTGFbeta-mediated FGF signaling is crucial for regulating cranial neural crest cell proliferation during frontal bone development.
The murine frontal bone derives entirely from the cranial neural crest (CNC) and consists of the calvarial (lateral) aspect that covers the frontal lobe of brain and the orbital aspect that forms the roof of bony orbit. TGFbeta and FGF signaling have important regulatory roles in postnatal calvarial development. Our previous study has demonstrated that conditional inactivation of Tgfbr2 in the ...
متن کاملBMP signaling is essential for development of skeletogenic and neurogenic cranial neural crest.
BMP signaling is essential for a wide variety of developmental processes. To evaluate the role of Bmp2/4 in cranial neural crest (CNC) formation or differentiation after its migration into the branchial arches, we used Xnoggin to block their activities in specific areas of the CNC in transgenic mice. This resulted in depletion of CNC cells from the targeted areas. As a consequence, the branchia...
متن کاملConcerted action of Msx1 and Msx2 in regulating cranial neural crest cell differentiation during frontal bone development
The homeobox genes Msx1 and Msx2 function as transcriptional regulators that control cellular proliferation and differentiation during embryonic development. Mutations in the Msx1 and Msx2 genes in mice disrupt tissue-tissue interactions and cause multiple craniofacial malformations. Although Msx1 and Msx2 are both expressed throughout the entire development of the frontal bone, the frontal bon...
