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.

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.

Histological observations of human embryos hitherto have been carried out using paraffin sections of 5 to 10 μm thickness, stained with the H-E method or simply with carmine. Because of the thickness, cells are arranged in 2 or 3 layers in one section and the histological details are not always clear. This book provides detailed morphological features of a very well preserved human embryo with fifteen somites. The sections are about 0.75 μm thick and stained with toluidine blue. The thinness of sections and clearness of staining reveal the histological details of this embryo very accurately. A complete set of high quality photomicrographs are presented for each of the selected sections. The high resolution of the photomicrographs will enable easy comparison with the literature. The clear presentation in this book of embryonic development is increasingly important and highly relevant for in-vitro fertilization, and thus of interest to reproductive biologists as well as anatomists.

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. Key Features: * 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

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.

The last ten years have shown a dramatic revolution in our understanding of early animal development. This new edition of the successful first edition describes the result of this revolution and explains how the body plan of an embryo emerges from the newly fertilised egg. The book starts with a critical discussion of embryological concepts and explains in simple terms the mathematics of cell states, morphogen gradients and threshold responses. The experimental evidence on the mechanism of regional specification in Xenopus, molluscs, annelids, ascidians as well as Caenorhabditis, the mouse, the chick and Drosophila is then discussed. The whole chapter devoted to the exciting developments in Drosophila provides a clear guide to the subject, including a new table outlining the developmentally important genes. The emphasis throughout is on conceptual clarity and unity: bringing together the mathematical models, embryological experiments and molecular biology into a single, comprehensive coherent account.
