Available in PDF, EPUB and Kindle. Book excerpt: Most people have some interest in embryos; this probably results, in part, from their interest in understanding the biological origins of themselves and their offspring and, increasingly, concerns about how environmental change such as pollution might affect human development. Obviously, et- cal considerations preclude experimental studies of human embryos and, c- sequently, the developmental biologist has turned to other species to examine this process. Fortunately, the most significant conclusion to be drawn from the experimental embryology of the last two decades is the manner in which orthologous or closely related molecules are deployed to mediate similar - velopmental processes in both vertebrates and invertebrates. The molecular mechanisms regulating processes fundamental to most animals, such as axial patterning or axon guidance, are frequently conserved during evolution. (It is now widely believed that the differences between phyla and classes are the result of new genes, arising mostly by duplication and divergence of extant sequences, regulating the appearance of derived characters. ) Other vertebrates are obviously most likely to use the same devel- mental mechanisms as humans and, within the vertebrate subphylum, the - parent degree of conservation of developmental mechanism is considerable. It has long been recognized that particular vertebrate species offer either d- tinct advantages in investigating particular stages of development or are - pecially amenable to particular manipulations. No single animal can provide all the answers because not all types of experiments can be carried out on a single species.

Download or read book Introduction to Molecular Embryology written by Jean Brachet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly 10 years have elapsed since I finished writing the first edition of Intro duction to Molecular Embryology. During this period, molecular embryology has made great strides forward, but without undergoing a major revolution; there fore, the general philosophy and outline of the book have remained almost un changed. However, all the chapters had to be almost completely rewritten in or der to introduce new facts and to eliminate findings which have lost interest or have been disproved. There was a major gap in the first edition of this book: very little was said about mammalian eggs despite their obvious interest for mankind. Research on mammalian eggs and embryos is so active today that this important topic deserves a full chapter in a book concerned with molecular embryology. Therefore, I am very thankful to my colleague Dr. Henri Alexandre, who has written a chapter on mammalian embryology (Chap. 9) and has prepared all the illustrations for this book.
Download or read book Self Organizing Systems written by F.Eugene Yates and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technological systems become organized by commands from outside, as when human intentions lead to the building of structures or machines. But many nat ural systems become structured by their own internal processes: these are the self organizing systems, and the emergence of order within them is a complex phe nomenon that intrigues scientists from all disciplines. Unfortunately, complexity is ill-defined. Global explanatory constructs, such as cybernetics or general sys tems theory, which were intended to cope with complexity, produced instead a grandiosity that has now, mercifully, run its course and died. Most of us have become wary of proposals for an "integrated, systems approach" to complex matters; yet we must come to grips with complexity some how. Now is a good time to reexamine complex systems to determine whether or not various scientific specialties can discover common principles or properties in them. If they do, then a fresh, multidisciplinary attack on the difficulties would be a valid scientific task. Believing that complexity is a proper scientific issue, and that self-organizing systems are the foremost example, R. Tomovic, Z. Damjanovic, and I arranged a conference (August 26-September 1, 1979) in Dubrovnik, Yugoslavia, to address self-organizing systems. We invited 30 participants from seven countries. Included were biologists, geologists, physicists, chemists, mathematicians, bio physicists, and control engineers. Participants were asked not to bring manu scripts, but, rather, to present positions on an assigned topic. Any writing would be done after the conference, when the writers could benefit from their experi ences there.
Download or read book A Conceptual History of Modern Embryology written by Scott F. Gilbert and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Glory to the science of embryology!" So Johannes Holtfreter closed his letter to this editor when he granted permission to publish his article in this volume. And glory there is: glory in the phenomenon of animals developing their complex morphologies from fertilized eggs, and glory in the efforts of a relatively small group of scientists to understand these wonderful events. Embryology is unique among the biological disciplines, for it denies the hegemony of the adult and sees value (indeed, more value) in the stages that lead up to the fully developed organism. It seeks the origin, and not merely the maintenance, of the body. And if embryology is the study of the embryo as seen over time, the history of embryology is a second-order derivative, seeing how the study of embryos changes over time. As Jane Oppenheimer pointed out, "Sci ence, like life itself, indeed like history, itself, is a historical phenomenon. It can build itself only out of its past. " Thus, there are several ways in which embryology and the history of embryology are similar. Each takes a current stage of a developing entity and seeks to explain the paths that brought it to its present condition. Indeed, embryology used to be called Entwicklungsgeschichte, the developmental history of the organism. Both embryology and its history interpret the interplay between internal factors and external agents in the causation of new processes and events.

Download or read book Gene Expression at the Beginning of Animal Development written by M.L. DePamphilis and published by Elsevier. This book was released on 2002-09-30 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The beginning of life may be a miracle to some, and a mystery to others, but it is certainly one of the most exciting and perhaps controversial fields of scientific investigation in the 21st century. Among the metazoa, life begins when an egg is fertilized by a sperm. The sperm provides a genetic blueprint from the father and perhaps some critical proteins. The egg provides a genetic blueprint from the mother together with a large reservoir of mRNAs and proteins that are required for DNA replication, cell division and the onset of zygotic gene expression. All of the thousands of genes in these two mature gametes are transcriptionally silent and remain so until fertilization. This work focuses on three biological systems, providing the reader with a clear understanding of the current state of affairs, and the ability to identify common principles as well as critical differences that are responsible for beginning the process of animal development. The essays presented will be of practical value to all those who are interested in improving fertilization in vitro, in designing novel methods of contraception, in developing preimplantation genetic diagnosis for various diseases, in cloning animals by transplanting nuclei from adult cells to an enucleated egg, and in the application of embryonic stem cells to curing genetic diseases or replacing damaged tissues. But above all, this volume is offered to those who simply have an insatiable curiosity about life and its beginnings.
Download or read book Story Of Genetics Development And Evolution The A Historical Dialogue written by Gaspar Jekely and published by World Scientific. This book was released on 2017-11-24 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique story offers an introductory conversation to genetics, embryology and evolution, taking us on a historical journey of biology through the ages. Using a series of dialogues between the Greek philosopher Democritus and his disciple Alkimos, we travel through time visiting eminent scientists throughout the centuries, from Lazzaro Spallanzani and Theodor Boveri to Francis Crick, Max Perutz and Christiane Nüsslein-Volhard. We find ourselves at the intersection of competing theories in biology and witness the progression from the debunking the theory of spontaneous generation to the mapping of the genome. Attention is given not only to the great successes in the field but also to the equally important and exciting failures.Originally published in Hungarian, The Story of Genetics, Development and Evolution provides a historical background to the life sciences, with complex scientific concepts stripped down and explained carefully for academics and anyone interested in going back to the roots and philosophies of scientific progress.Translated from: Jékely G Master, are you awake?

Download or read book Stem Cells Regenerative Medicine written by Krishnarao Appasani and published by Springer Science & Business Media. This book was released on 2010-11-01 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Defined as, “The science about the development of an embryo from the fertilization of the ovum to the fetus stage,” embryology has been a mainstay at universities throughout the world for many years. Throughout the last century, embryology became overshadowed by experimental-based genetics and cell biology, transforming the field into developmental biology, which replaced embryology in Biology departments in many universities. Major contributions in this young century in the fields of molecular biology, biochemistry and genomics were integrated with both embryology and developmental biology to provide an understanding of the molecular portrait of a “development cell.” That new integrated approach is known as stem-cell biology; it is an understanding of the embryology and development together at the molecular level using engineering, imaging and cell culture principles, and it is at the heart of this seminal book. Stem Cells and Regenerative Medicine: From Molecular Embryology to Tissue Engineering is completely devoted to the basic developmental, cellular and molecular biological aspects of stem cells as well as their clinical applications in tissue engineering and regenerative medicine. It focuses on the basic biology of embryonic and cancer cells plus their key involvement in self-renewal, muscle repair, epigenetic processes, and therapeutic applications. In addition, it covers other key relevant topics such as nuclear reprogramming induced pluripotency and stem cell culture techniques using novel biomaterials. A thorough introduction to stem-cell biology, this reference is aimed at graduate students, post-docs, and professors as well as executives and scientists in biotech and pharmaceutical companies.

Download or read book Scientific Frontiers in Developmental Toxicology and Risk Assessment written by National Research Council and published by National Academies Press. This book was released on 2000-12-21 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Frontiers in Developmental Toxicology and Risk Assessment reviews advances made during the last 10-15 years in fields such as developmental biology, molecular biology, and genetics. It describes a novel approach for how these advances might be used in combination with existing methodologies to further the understanding of mechanisms of developmental toxicity, to improve the assessment of chemicals for their ability to cause developmental toxicity, and to improve risk assessment for developmental defects. For example, based on the recent advances, even the smallest, simplest laboratory animals such as the fruit fly, roundworm, and zebrafish might be able to serve as developmental toxicological models for human biological systems. Use of such organisms might allow for rapid and inexpensive testing of large numbers of chemicals for their potential to cause developmental toxicity; presently, there are little or no developmental toxicity data available for the majority of natural and manufactured chemicals in use. This new approach to developmental toxicology and risk assessment will require simultaneous research on several fronts by experts from multiple scientific disciplines, including developmental toxicologists, developmental biologists, geneticists, epidemiologists, and biostatisticians.
Download or read book Genome Multiplication in Growth and Development written by Vsevolod I︠A︡kovlevich Brodskiĭ and published by CUP Archive. This book was released on 1985 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This authoritative account of the developmental biology of genome multiplication, the reproduction of the genetic material that results in polyploid and polytene cells, is based on many years' study by its authors. Polyploid and polytene cells regularly occur in a wide range of organisms, including mammals, invertebrates, plants and protozoa. The cells also have a particular significance for the function of the tissues and organs of which they are an integral part. The first part of the book details the origin of polyploidy and polyteny in the normal development of many tissue systems. In the second part the various modes of genome multiplication, its control, and its biological significance are discussed. The book is fully referenced citing literature published in many languages, and is particularly valuable in that it includes scientific results previously available only in Russian.
Download or read book Molecular Methods in Developmental Biology written by Matt Guille and published by Springer Science & Business Media. This book was released on 2008-02-03 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The process whereby a single cell, the fertilized egg, develops into an adult has fascinated for centuries. Great progress in understanding that process, h- ever, has been made in the last two decades, when the techniques of molecular biology have become available to developmental biologists. By applying these techniques, the exact nature of many of the interactions responsible for forming the body pattern are now being revealed in detail. Such studies are a large, and it seems ever-expanding, part of most life-science groups. It is at newcomers to this field that this book is primarily aimed. A number of different plants and animals serve as common model org- isms for developmental studies. In Molecular Methods in Developmental Bi- ogy: Xenopus and Zebrafish, a range of the molecular methods applicable to two of these organisms are described, these are the South African clawed frog, Xenopus laevis, and the zebrafish, Brachydanio rerio. The embryos of both of these species develop rapidly and externally, making them particularly suited to investigations of early vertebrate development. However, both Xenopus and zebrafish have their own advantages and disadvantages. Xenopus have large, robust embryos that can be manipulated surgically with ease, but their pseudotetraploidy and long generation time make them unsuitable candidates for genetics. This disadvantage may soon be overcome by using the diploid Xenopus tropicalis, and early experiments are already underway. The transp- ent embryos of zebrafish render them well-suited for in situ hybridization and immunohistochemistry, and good for observing mutations in genetic screens.
Download or read book Developmental Biology Protocols Volumes I II and III written by Rocky S. Tuan and published by Humana Press. This book was released on 1999-12-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fast-growing field of developmental biology provides a unifying framework that integrates anatomy, physiology, genetics, biochemistry, cellular and molecular biology, as well as evolutionary biology. The number of "reference" publications that deal specifically with the practical aspects of experimental developmental biology are relatively scarce. Developmental Biology Protocols grows out of this need for a comprehensive laboratory manual that provides the readers with the principles, background, rationale, as well as practical protocols, for studying and analyzing the events of embryonic development. Its highly practical format and wide range of model systems and multidisciplinary experimental techniques attest to the authors' determination to provide a balanced presentation of both background information and actual laboratory details. This three-volume compilation of relevant and useful information will be a well-utilized resource for both the students and teachers of developmental biology at all levels. Developmental Biology Protocols offers the most comprehensive, cutting-edge collection of contemporary experimental methods available for the study of embryogenesis and development. Written by an interdisciplinary team of leading scientific investigators, this authoritative collection provides step-by-step instructions for successful laboratory execution. Topics range from animal model system acquisition to molecular genetics, and include high resolution imaging, transgenesis, teratology, comparative anatomy and embryology, the characterization of embryonic structure and function, the analysis of cell function, and the regulation of gene activity. In addition to many unique, new experimental protocols, the authors have also utilized a host of experimental approaches used in other disciplines applicable to the study of development. Comprehensive and richly annotated, Developmental Biology Protocols constitutes the gold-standard reference for today's developmental biologists.
