This book was released on 2010 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Wnt/β-catenin signaling pathway is a key regulator of cell fate specification, differentiation, and growth in multiple systems throughout the animal kingdom. In vertebrate posterior neural development, Wnt/β-catenin signaling controls this complex multistep process. It initially induces the posterior regions of the nervous system, including the mid-hindbrain border, hindbrain, spinal cord and neural crest, and then subsequently fine-tunes the pattern of each region and determines the different cell fates within them. In this review, we explore the function of the Wnt/β-catenin pathway during the formation of these specific posterior neural regions. We have examined the important transcriptional targets of the Wnt/β-catenin pathway acting downstream to mediate its morphogenetic activity. Different regulatory networks are activated in different posterior neural regions, and these networks induce specific neural cell types in each region. Eludidating how each of these networks specify different cell fates is crucial for understanding the basic tenets of how Wnt morphogenetic activity induces the posterior nervous system during the earliest stages of vertebrate development.

Book Synopsis Signalling Pathways in Embryonic Development by : Juan J. Sanz-Ezquerro
Download or read book Signalling Pathways in Embryonic Development written by Juan J. Sanz-Ezquerro and published by Frontiers Media SA. This book was released on 2017-11-30 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: The formation of a complex multicellular organism from a single cell is one of the most amazing processes of biology. Embryonic development is characterised by the careful regulation of cellular behaviours such that cells proliferate, migrate, differentiate and form tissues at the correct place and time. These processes are genetically controlled and depend both on the history of cells, their lineage, and on the activities of signalling pathways, which coordinate the cell interactions leading to organogenesis. The aim of the Frontiers research topic “Signalling pathways in embryonic development” has been to provide a forum for experts in cell and developmental biology to share recent advances in the field of signalling during embryonic development. Sixteen articles in a variety of formats are united in this Topic, offering a valuable collection for researchers looking for an update in the knowledge of signalling pathways operating during embryogenesis. The works, focused mainly on vertebrates, explore different aspects of this theme from cell communication to organ formation and have implications for areas as distant as evolution or pathology. Understanding developmental signalling pathways is important for several reasons. It gives us information about basic mechanisms of cell function and interactions needed for morphogenesis and organogenesis. It uncovers the basis of congenital malformations, since errors at any step of cell signalling during development are a major cause of defects. This fundamental insight gives us clues to understand the mechanisms operating in evolution that explain diversity in form and function. And finally, it allows the identification of possible causes of disease in the adult organism (such as cancer or degenerative diseases) pinpointing possible targets for therapeutic approaches.
Book Synopsis The Neural Crest by : Nicole Le Douarin
Download or read book The Neural Crest written by Nicole Le Douarin and published by Cambridge University Press. This book was released on 1999-11-28 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 1999 edition of The Neural Crest contains comprehensive information about the neural crest, a structure unique to the vertebrate embryo, which has only a transient existence in early embryonic life. The ontogeny of the neural crest embodies the most important issues in developmental biology, as the neural crest is considered to have played a crucial role in evolution of the vertebrate phylum. Data that analyse neural crest ontogeny in murine and zebrafish embryos have been included in this revision. This revised edition also takes advantage of recent advances in our understanding of markers of neural crest cell subpopulations, and a full chapter is now devoted to cell lineage analysis. The major research breakthrough since the first edition has been the introduction of molecular biology to neural crest research, enabling an elucidation of many molecular mechanisms of neural crest development. This book is essential reading for students and researchers in developmental biology, cell biology, and neuroscience.
Book Synopsis Requirements for Wnt Signaling in Morphogenesis of the Neural Crest, Neural Tube, and Craniofacial Skeleton of Zebrafish Embryos by : Sarah Piloto
Download or read book Requirements for Wnt Signaling in Morphogenesis of the Neural Crest, Neural Tube, and Craniofacial Skeleton of Zebrafish Embryos written by Sarah Piloto and published by . This book was released on 2010 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: How are morphogenesis, growth, and differentiation orchestrated to generate multiple functioning organs during embryonic development? For my thesis studies I have focused on understanding the role of Wnt signaling in several organs and cell types during zebrafish embryonic development. I studied context-specific requirements for Wnt signals to pattern the neural crest (NC)-derived pigment cells and craniofacial skeleton. Additionally, I studied the roles of Ovo transcription factors, putative Wnt targets, in the formation of the central nervous system (CNS). The CNS rudiment, the neural tube, forms by the rolling into a tube of the neuroectoderm during neurulation. NC cells form adjacent to the neuroectoderm but migrate throughout the embryo to differentiate into a variety of cell types including cartilage cells that give rise to the craniofacial skeleton and pigment cells of the skin. Differential Cadherin expression differentiates the neural tube from NC during neurulation. Additionally, a sequential Cadherin code, partially controlled by Wnt signaling, is also required for NC cell migration. Wnt signaling is well known in embryogenesis and cancer, playing multiple roles in several aspects of development. I have isolated and characterized requirements in neural tube morphogenesis for two zebrafish orthologues of the Ovo family of transcription factors, ovo1 and ovo3. I also established zebrafish ovo1 as a target of Wnt signaling required for the migration of the NC-derived pigment cells and provided the first link between Ovo transcription factors and N-cadherin (Ncad) regulation via transcriptional control of Rab Gtpases known to control trafficking of molecules within the cell. Wnt signaling also functions to pattern the NC-derived craniofacial skeleton. Using temporally controlled gain-of-function studies I have shown that Wnt signaling is required for the formation of the lower jaw skeleton by coordinating morphogenesis and growth. My research shows that Dkk1 overexpression inhibits Wnt signaling, which is sufficient to inhibit cell proliferation resulting in craniofacial abnormalities. Although expressed by the adjacent endoderm, Dkk1 acts as an extrinsic cue to organize growth and morphogenesis of the craniofacial skeleton.

Book Synopsis Transcriptional Control of Neural Crest Development by : Brian L. Nelms
Download or read book Transcriptional Control of Neural Crest Development written by Brian L. Nelms and published by Morgan & Claypool Publishers. This book was released on 2010 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: The neural crest is a remarkable embryonic population of cells found only in vertebrates and has the potential to give rise to many different cell types contributing throughout the body. These derivatives range from the mesenchymal bone and cartilage comprising the facial skeleton, to neuronal derivatives of the peripheral sensory and autonomic nervous systems, to melanocytes throughout the body, and to smooth muscle of the great arteries of the heart. For these cells to correctly progress from an unspecifi ed, nonmigratory population to a wide array of dynamic, differentiated cell types-some of which retain stem cell characteristics presumably to replenish these derivatives-requires a complex network of molecular switches to control the gene programs giving these cells their defi ning structural, enzymatic, migratory, and signaling capacities. This review will bring together current knowledge of neural crest-specifi c transcription factors governing these progressions throughout the course of development. A more thorough understanding of the mechanisms of transcriptional control in differentiation will aid in strategies designed to push undifferentiated cells toward a particular lineage, and unraveling these processes will help toward reprogramming cells from a differentiated to a more naive state.
