Available in PDF, EPUB and Kindle. Book excerpt: Somite development is a unique and important topic; unique because somitic mesoderm is the first tissue to become segmented, important because the somites - once established - exert a profound influence on other seg mental structures which form later. Somite development is of interest at a number of levels. In one aspect, demarcation of a specific number of somites and size regulation, it is a particularly intriguing example of embryonic pattern formation, 'especially in vew of its possible relation to homoeobox-controlled segmentation in insects. At another level, somite development has long been studied by compara tive anatomists, but only recently has new light been thrown on such sub jects as segmentation of the head, proposed in the 18th century by Goethe and now a live issue for developmental biologists. Somit es are simple when they first appear, but very complex structures arise from them. These include the vertebrae and the axial and other muscles and consequently there is a wealth of morphogenetic problems to be explored. Sometimes their morphogenesis is disturbed, by genetic or environ mental factors, and there are many clinical conditions which arise as a result.

Available in PDF, EPUB and Kindle. Book excerpt: Building the Most Complex Structure on Earth provides readers with a basic biological education an easy and understandable introduction into a new epigenetic theory of development and evolution. This is a novel theory that describes the epigenetic mechanisms of the development and evolution of animals and explains the colossal evolution and diversification of animals from a new post-genetic perspective. Modern biology has demonstrated the existence of a common genetic toolkit in the animal kingdom, but neither the number of genes nor the evolution of new genes is responsible for the development and evolution of animals. The failure to understand how the same genetic toolkit is used to produce millions of widely different animal forms remains a perplexing conundrum in modern biology. The novel theory shows that the development and evolution of the animal kingdom are functions of epigenetic mechanisms, which are the competent users of the genetic toolkit. Provides a comprehensive view of the epigenetic aspects of reproduction, development, and evolution. Highly rigorous, but simple enough for readers with only a basic knowledge of biology.

Download or read book The Origin and Fate of Somites written by North Atlantic Treaty Organization. Scientific Affairs Division and published by IOS Press. This book was released on 2001 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text investigates advances in the field of sommites and integrates them into the accumulated knowledge of how sommites form and differentiate. Although the book focuses on the formation and patterning of somites it will encompass a broader life history of a somite. Topics include events attending gastrulation, which foreshadow somite formation, to the subsequent contributions that somites make to neighbouring regions such as musculature, limbs and axial skeleton. There is also a discussion of the origins of cells that eventually give rise to somites. This book brings together investigators from NATO and NATO partner countries who are employing both classical and molecular approaches to the analysis of somitogenesis.
Download or read book Somitogenesis Part 2 written by and published by Elsevier. This book was released on 2000-01-10 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chapters contained in this two-volume set provide a broad perspective on the novel strategies and conceptual paradigms that drive the current resurgence of interest in somitogenesis - the process by which somites form and elaborate differentiated tissues and structures. Because somites are a ubiquitous feature of vertebrate embryos, they can be studied in a variety of experimental animal models including those amenable to genetic (zebrafish, mammalian), molecular/genetic (mammalian, avian) as well as those already well established for classical experimental embryological and cell biological studies (amphibians, avian). The wide variety of experimental approaches to somitogenesis that are presented in these volumes will leave the reader with a broad perspective on how current research in somitogenesis is helping to solve fundamental questions in vertebrate development and morphogenesis. Novel transcriptional mechanisms that control repetitive pattern formation Wide-scale genetic screens for mutations affecting somitogenesis Molecular/genetic control of pattern and tissue formation during somitogenesis Transplantation of mouse embryo somites Classical embryological approaches and concepts Evolutionary perspectives on somitogenesis

Download or read book Epigenetic Principles of Evolution written by Nelson R Cabej and published by Elsevier. This book was released on 2011-11-22 with total page 847 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first and only book, so far, to deal with the causal basis of evolution from an epigenetic view. By revealing the epigenetic "user" of the "genetic toolkit", this book demonstrates the primacy of epigenetic mechanisms and epigenetic information in generating evolutionary novelties. The author convincingly supports his theory with a host of examples from the most varied fields of biology, by emphasizing changes in developmental pathways as the basic source of evolutionary change in metazoans. Original and thought provoking--a radically new theory that overcomes the present difficulties of the theory of evolution Is the first and only theory that uses epigenetic mechanisms and principles for explaining evolution of metazoans Takes an integrative approach and shows a wide range of learning

Book excerpt: Bones and Cartilage provides the most in-depth review and synthesis assembled on the topic, across all vertebrates. It examines the function, development and evolution of bone and cartilage as tissues, organs and skeletal systems. It describes how bone and cartilage develop in embryos and are maintained in adults, how bone is repaired when we break a leg, or regenerates when a newt grows a new limb, or a lizard a new tail. The second edition of Bones and Cartilage includes the most recent knowledge of molecular, cellular, developmental and evolutionary processes, which are integrated to outline a unified discipline of developmental and evolutionary skeletal biology. Additionally, coverage includes how the molecular and cellular aspects of bones and cartilage differ in different skeletal systems and across species, along with the latest studies and hypotheses of relationships between skeletal cells and the most recent information on coupling between osteocytes and osteoclasts All chapters have been revised and updated to include the latest research. Offers complete coverage of every aspect of bone and cartilage, with updated references and extensive illustrations Integrates development and evolution of the skeleton, as well a synthesis of differentiation, growth and patterning Treats all levels from molecular to clinical, embryos to evolution, and covers all vertebrates as well as invertebrate cartilages Includes new chapters on evolutionary skeletal biology that highlight normal variation and variability, and variation outside the norm (neomorphs, atavisms) Updates hypotheses on the origination of cartilage using new phylogenetic, cellular and genetic data Covers stem cells in embryos and adults, including mesenchymal stem cells and their use in genetic engineering of cartilage, and the concept of the stem cell niche

This book was released on 2012-12-06 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this Atlas I want to share with my fellow clinicians the fascina tion I experienced while discovering the marvels of embryonic development. Why haven't these marvels excited me before? I believe that the use of schemata and drawings or photographs of animal embryos, commonly used in textbooks of embryology, simply did not appeal to me as a clinician. Only actual photo graphs of human embryos can establish the bond necessary for interaction. Just imagine the excitement when you find out how many struc tures you can recognize in a 5-week-old embryo, barely measuring 1 cm in length. But our fascination does not stop here. The pro gression of changes taking place during the next 3 weeks is so rapid that at the time when the embryo measures 3 cm, all structures familiar to us are not only easily recognizable, but also already in their anatomical position. How can we hide our amazement when we realize that such a state of perfection is present in an embryo a bit longer than the distal phalanx of our little finger? At 8 weeks the embryonic period ends and the fetal one starts. Although the shape and the relative size of bones, joints, muscles, nerves, and vessels will undergo changes, the basic elements are all in place. This implies that major malformations must develop during the embryonic period.
