Mechanobiology During Vertebrate Organ Development
Neural crest cells are one of many migrating cell types found in vertebrate tissues. Neural crest specification occurs between the neural plate and epidermal region during vertebrate embryogenesis, and is regulated at the gene level by appropriate concentrations of cell signaling proteins such as bone morphogenetic protein (BMP), fibroblast growth factor (FGF), and Wnt (reviewed by Meulemans and Bronner-Fraser 2004). Many genes participate in this regional network to specify the neural crest. After neural tube closure, neural crest cells start migrating to the ventral half of the embryo, and the resultant epithelial-to-mesenchymal transformation dissociates the neural crest cells from the epidermis. The dissociated neural crest cells then start to move ventrally.
