This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cell rearrangement is one of the fundamental mechanisms underlying tissue morphogenesis. In epithelial tissues, cells rearrange without losing their tight neighbor interactions by junction remodeling according to a topological T1 transition, i. e. collapse of a junction followed by extension of a new junction in perpendicular orientation. The minimal functional units are cell quadruplets with two old and two new neighbors. The driving force for junction remodeling is provided by acto-myosin contractility in old neighbors. By now it has been unclear whether non-autonomous mechanism is involv...

Available in PDF, EPUB and Kindle. Book excerpt: For more than 30 years, Current Topics in Developmental Biology has provided a forum for dissemination and discussion of new ideas and thought in developmental biology. Bringing together a series of articles on the structural, functional, and developmental characteristics of epithelials, this thematic volume represents a timely and valuable contribution to an exciting and multidisciplinary field of study. Because defects in epithelial function and growth control play a major role in human disease-cancerous tumors, spina bifida, cardiac malformations, for example-this volume will be of particular interest to researchers working in cancer drug design and development and those working in therapeutic areas to treat developmental abnormalities. Coverage of current research findings and thought on cell-cell and cell-extracellular matrix interactions gives researchers a better understanding of the processes of remodeling and morphogenesis, which are critical to the development of drugs aimed at disrupting the early formation and proliferation of cancerous tumors Inclusion of chapters that discuss the most contemporary thought on cell polarity and tissue morphogenesis, providing researchers with a better understanding of the control of cellular organization and polarity (particularly important to researchers who are developing treatments for developmental abnormalities and those working in cancer drug development) Use of a variety of animal models, allowing researchers to compare and contrast the molecular mechanisms that underlie cell-cell and cell-extracelluar matrix interactions in a variety of research models

Download or read book Drosophila Eye Development written by Kevin Moses and published by Springer Science & Business Media. This book was released on 2002-03-12 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: 1 Kevin Moses It is now 25 years since the study of the development of the compound eye in Drosophila really began with a classic paper (Ready et al. 1976). In 1864, August Weismann published a monograph on the development of Diptera and included some beautiful drawings of the developing imaginal discs (Weismann 1864). One of these is the first description of the third instar eye disc in which Weismann drew a vertical line separating a posterior domain that included a regular pattern of clustered cells from an anterior domain without such a pattern. Weismann suggested that these clusters were the precursors of the adult ommatidia and that the line marks the anterior edge of the eye. In his first suggestion he was absolutely correct - in his second he was wrong. The vertical line shown was not the anterior edge of the eye, but the anterior edge of a moving wave of patterning and cell type specification that 112 years later (1976) Ready, Hansen and Benzer would name the "morphogenetic furrow". While it is too late to hear from August Weismann, it is a particular pleasure to be able to include a chapter in this Volume from the first author of that 1976 paper: Don Ready! These past 25 years have seen an astonishing explosion in the study of the fly eye (see Fig.

This book was released on 2013-03-09 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: " . . . but our knowledge is so weak that no philosoph er will ever be able to completely explore the nature of even a fly . . . " * Thornas Aquinas "In Syrnbolurn Apostolorum" 079 RSV p/96 This is a monograph on embryogenesis of the fruit fly Drosophi la melanogaster conceived as a reference book on morphology of embryonie development. A monograph of this extent and con tent is not yet available in the literature of Drosophila embryolo gy, and we believe that there is areal need for it. Thanks to the progress achieved during the last ten years in the fields of devel opmental and molecular genetics, work on Drosophila develop ment has considerably expanded creating an even greater need for the information that we present here. Our own interest for wildtype embryonie development arose several years ago, when we began to study the development of mutants. While those studies were going on we repeatedly had occasion to state in sufficiencies in the existing literature about the embryology of the wildtype, so that we undertook investigating many of these problems by ourselves. Convinced that several of our colleagues will have encountered similar difficulties we decided to publish the present monograph. Although not expressely recorded, Thomas Aquinas probably referred to the domestic fly and not to the fruit fly. Irrespective of which fly he meant, however, we know that Thomas was right in any case.

Download or read book Extracellular Matrix in Development written by Douglas W. DeSimone and published by Springer Science & Business Media. This book was released on 2013-03-15 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cells in the developing embryo depend on signals from the extracellular environment to help guide their differentiation. An important mediator in this process is the extracellular matrix – secreted macromolecules that interact to form large protein networks outside the cell. During development, the extracellular matrix serves to separate adjacent cell groups, participates in establishing morphogenic gradients, and, through its ability to interact directly will cell-surface receptors, provides developmental clocks and positional information. This volume discusses how the extracellular matrix influences fundamental developmental processes and how model systems can be used to elucidate ECM function. The topics addressed range from how ECM influences early development as well as repair processes in the adult that recapitulate developmental pathways.

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.

This book was released on 2012-11-19 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: ​​​​​​​Prominin-1 or otherwise known as CD133 is a glycoprotein that is present in humans and mice. Since the first description of prominin in 1997, in mouse neuroepithelial cells and in human hematopoietic stem cells as AC133 antigen, this molecule has aroused a large interest especially, as a stem cell marker, that gave rise to an ever growing body of publications and more recently its expression in cancer stem cells. Controversies as to its role as a cancer stem and its detection in different models, as well as its use as a prognostic marker have emerged. Yet, beyond its use as a stem cell and cancer stem cell marker, prominin-1/CD133 displays unique biological features and appears of importance in other processes like for example in retinal biogenesis. Indeed, this five-transmembrane plasma membrane glycoprotein, which marks membrane protrusions is associated with several essential processes like cell polarity, asymmetric cell division and membrane remodeling. We propose to review current knowledge about this intriguing molecule and present pertinent information to determine the biological role of prominins and assess their importance in medicine and cancer research. The primary audience for this book is geared towards scientists and researchers with interest in cancer stem cells, stem cells, cell biology, neurobiology, and regenerative medicine.

Download or read book The Dynamics of Living Systems written by Thomas Lecuit and published by Collège de France. This book was released on 2020-11-16 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can we explain the fundamental paradox of living matter, which combines stability and robustness of form with constant internal dynamics? It is not only the genetic information contained in every cell, but also numerous stochastic biomolecular processes that are at work in morphogenesis. In addition, the shaping of an organism is driven by mechanical forces that operate within and between cells, across tissues and organs. The dynamics of morphogenesis is a self-organized process that emerges from biological control and physical constraints at all scales. Its study is currently bringing together a fast-growing interdisciplinary community that observes, analyses and models living organisms.

Download or read book Molecular Genetics of Axial Patterning Growth and Disease in Drosophila Eye written by Amit Singh and published by Springer Nature. This book was released on 2020-05-18 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drosophila melanogaster (fruit fly) is a highly versatile model with a genetic legacy of more than a century. It provides powerful genetic, cellular, biochemical and molecular biology tools to address many questions extending from basic biology to human diseases. One of the most important questions in biology is how a multi-cellular organism develops from a single-celled embryo. The discovery of the genes responsible for pattern formation has helped refine this question and has led to other questions, such as the role of various genetic and cell biological pathways in regulating the process of pattern formation and growth during organogenesis. The Drosophila eye model has been extensively used to study molecular genetic mechanisms involved in patterning and growth. Since the genetic machinery involved in the Drosophila eye is similar to humans, it has been used to model human diseases and homology to eyes in other taxa. This updated second edition covers current progress in the study of molecular genetic mechanisms of pattern formation, mutations in axial patterning, genetic regulation of growth, and more using the Drosophila eye as a model.

This book was released on 2013-04-18 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: For anybody capable of an emotional response to it, any view of a developing organism should give birth to a feeling of amazement and even admiration, whether this development is seen directly, or in the form of a time lapse film, or even if mentally reconstructed from a series of static images. We ask ourselves how such seemingly primitive eggs or pieces of tissue, without any obvious intervention from outside, so regularly transform themselves into precisely constructed adult organisms. If we try to formulate what amazes us most of all about development, the answer will probably be that it is the internal capacity of developing organisms themselves to create new structures. How, then, can we satisfy our amazement in ways that are more or less reasonable, as well as scientifically valuable? This depends, first of all, on what position we choose to regard embryonic development as occupying among other structure creating processes, even including human activities. On the one hand, one might regard the development of organisms as a highly specialized class of processes, unique to themselves and alien to the general laws of nature, or at least not derivable from them and more akin to the deliberate acts of our own human behaviour. In that case our task would become reduced to a search for some specific 'instructions' for each next member of such a class. Whether in an overt or hidden form, some such ideology seems to dominate in present day developmental biology.

Download or read book The Comparative Embryology of Sponges written by Alexander V. Ereskovsky and published by Springer Science & Business Media. This book was released on 2010-03-27 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the major questions in the evolution of animals is the transition from unicellular to multicellular organization, which resulted in the emergence of Metazoa through a hypothetical Urmetazoa. The Comparative Embryology of Sponges contains abundant original and literary data on comparative embryology and morphology of the Porifera (Sponges), a group of 'lower Metazoa'. On the basis of this material, original typization of the development of Sponges is given and the problems concerning origin and evolution of Porifera and their ontogenesis are discussed. A morphogenetic interpretation of the body plan development during embryogenesis, metamorphosis and asexual reproduction in Sponges is proposed. Special attention is given to the analysis of characteristic features of the ontogenesis in Porifera. The book pursues three primary goals: 1) generalization of all existing information on individual development of sponges, its classification and a statement according to taxonomical structure of Porifera; 2) revealing of heterogeneity of morphogenesis and peculiarities of ontogeneses in various clades of Porifera, and also their correlations with the organization, both adult sponges, and their larvae; 3) revealing homology of morphogeneses in both Porifera and Eumetazoa, testifying to the general evolutionary roots of multicellular animals, and peculiar features of sponges' morphogeneses and ontogenesis. This book will be of interest to embryologists, zoologists, morphologists and researchers in evolutionary biology.
