“…NC cells are subdivided into cranial (Graham et al, 2004;Cordero et al, 2011), cardiac (Kirby et al, 1983;Keyte and Hutson, 2012), vagal (Kuo and Erickson, 2011;Peters-Van Der Sanden et al, 1993;Burns and Le Douarin, 1998;Yntema and Hammond, 1954), trunk (Bronner-Fraser and Fraser, 1989;Serbedzija et al, 1994) and sacral (Burns and Le Douarin, 1998;Anderson et al, 2006) NC cells due to their diversity along neuraxis ( Fig.1.1A). Upon closure of the neural plate, NC cells undergo epithelial-to-mesenchymal transition (EMT) (Ahlstrom and Erickson, 2009;Alfandari et al, 2010;Berndt et al, 2008 andDuband, 2010) allowing them to delaminate from prospective neural tube and migrate throughout the embryo ( Fig.1.1B). Many of the genes involved in EMT of NC cells are transcription factors which have been also classified as proto-oncogenes contributing to cancer development (Thiery, 2003).…”
