Notch Signaling Regulates the Differentiation of Neural Crest From

Neural crest cells originate from neuroectoderm at the border between the neural plate and the Neural crest cells are specified at the border between the neural epiderm (Meulemans and Bronner-Fraser, 2004), and they are plate and the epiderm. They are capable of differentiating into marked by the expression of genes that are specific for the neural- various somatic cell types, including craniofacial and peripheral plate border, such as DLX5, MSX1, MSX2 and ZIC1. Later, during nerve tissues. Notch signaling plays important roles during the neural-tube folding process, neural crest cells remain within neurogenesis; however, its function during human neural crest the neural folds and subsequently localize inside the dorsal development is poorly understood. Here, we generated self- portion of the neural tube. These premigratory neural crest cells renewing premigratory neural-crest-like cells (pNCCs) from human express specifier genes, such as SNAIL (also known as SNAI1), pluripotent stem cells (hPSCs) and investigated the roles of Notch SLUG (also known as SNAI2), SOX10 and TWIST1 (LaBonne and signaling during neural crest differentiation. pNCCs expressed Bronner-Fraser, 2000; Mancilla and Mayor, 1996). Following the various neural-crest-specifier genes, including SLUG (also known formation of the neural tube, premigratory neural crest cells as SNAI2), SOX10 and TWIST1, and were able to differentiate into undergo an epithelial-to-mesenchymal transition (EMT) and most neural crest derivatives. -
The Migration of Neural Crest Cells and the Growth of Motor Axons Through the Rostral Half of the Chick Somite

RICKMANN, J. W. FAWCETT The Salk Institute and The Clayton Foundation for Research, California division, P.O. Box 85800, San Diego, CA 92138, U.S.A. AND R. J. KEYNES Department of Anatomy, University of Cambridge, Downing St, Cambridge, CB2 3DY, U.K. SUMMARY We have studied the pathway of migration of neural crest cells through the somites of the developing chick embryo, using the monoclonal antibodies NC-1 and HNK-1 to stain them. Crest cells, as they migrate ventrally from the dorsal aspect of the neural tube, pass through the lateral part of the sclerotome, but only through that part of the sclerotome which lies in the rostral half of each somite. This migration pathway is almost identical to the path which pre- sumptive motor axons take when they grow out from the neural tube shortly after the onset of neural crest migration. In order to see whether the ventral root axons are guided along this pathway by neural crest cells, we surgically excised the neural crest from a series of embryos, and examined the pattern of axon outgrowth approximately 24 h later. In somites which contained no neural crest cells, ventral root axons were still found only in the rostral half of the somite, although axonal growth was slightly delayed. These axons were surrounded by sheath cells, which had presumably migrated out of the neural tube, to a point about 50 jan proximal to the growth cones. -
