Living Embryos: An Introduction to the Study of Animal Development covers the growth of an animal embryo, specifically the sequence developmental events of an egg. This book addresses the mammalian embryo as a homograph and demonstrates early vertebrate development mechanisms. Some of the topics covered in the book are the early embryology, development, and growth of the frog, mammals, chick, rabbit, arthropods, polychaetes, nematodes, molluscs, and tunicates. Other chapters deal with the formation of the nervous, muscular, and alimentary systems. These topics are followed by the analysis of the development of fishes. The discussion then shifts to the method of fertilization. The last chapters examine the formation of cleavage, cleavage geometry, embryonic membranes, and organization of the egg. The book can provide useful information to embryologists, biologists, students, and researchers.

Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

Living Embryos: An Introduction to the Study of Animal Development, Revised Second Edition presents the processes of development as seen throughout the animal kingdom. This book discusses the development of the organ systems of vertebrates. Comprised of 41 chapters, this edition starts with an overview of the history of the study of embryology, which is concerned with the process by which the adult arises from the fertilized egg. This text then discusses the role of the sperm in the determination of bilateral symmetry. Other chapters consider the development of the frog in order to give a basis for comparison with other species. This book discusses as well the structure of the hen's egg and illustrates the various stages of the development of the chick. The final chapter deals with animal evolution, which produces a wide variety of animal forms. Embryologists, zoologists, medical students, graduate students, university lecturers, and teachers will find this book extremely useful.

Eggs of all animals contain mRNAs and proteins that are supplied to or deposited in the egg as it develops during oogenesis. These maternal gene products regulate all aspects of oocyte development, and an embryo fully relies on these maternal gene products for all aspects of its early development, including fertilization, transitions between meiotic and mitotic cell cycles, and activation of its own genome. Given the diverse processes required to produce a developmentally competent egg and embryo, it is not surprising that maternal gene products are not only essential for normal embryonic development but also for fertility. This review provides an overview of fundamental aspects of oocyte and early embryonic development and the interference and genetic approaches that have provided access to maternally regulated aspects of vertebrate development. Some of the pathways and molecules highlighted in this review, in particular, Bmps, Wnts, small GTPases, cytoskeletal components, and cell cycle regulators, are well known and are essential regulators of multiple aspects of animal development, including oogenesis, early embryogenesis, organogenesis, and reproductive fitness of the adult animal. Specific examples of developmental processes under maternal control and the essential proteins will be explored in each chapter, and where known conserved aspects or divergent roles for these maternal regulators of early vertebrate development will be discussed throughout this review.

This reference on veterinary embryology covers general embryology, i.e. the development from the formation of the gametes over fertilization and initial embryogenesis up to the stage where organ formation is initiated, and special embryology, i.e. the development of the organ systems. Moreover, the book also includes a section on teratology, one on assisted reproductive technologies and one on veterinary and societal aspects. Written with the veterinary student in mind, this textbook is written in an accessible style with high quality colour illustrations and line drawings. Succinct and accessible 300 high-quality colour illustrations Written for undergraduates and invaluable for graduates wishing to brush up

Since 1998, the volume of research being conducted using human embryonic stem (hES) cells has expanded primarily using private funds because of restrictions on the use of federal funds for such research. Given limited federal involvement, privately funded hES cell research has thus far been carried out under a patchwork of existing regulations, many of which were not designed with this research specifically in mind. In addition, hES cell research touches on many ethical, legal, scientific, and policy issues that are of concern to the public. This report provides guidelines for the conduct of hES cell research to address both ethical and scientific concerns. The guidelines are intended to enhance the integrity of privately funded hES cell research by encouraging responsible practices in the conduct of that research.

Sea urchin eggs are objects of wonder for the student who sees them for the first time under the microscope. The formation of the fertil ization membrane after insemination, the beauty of mitotic cleavage, the elegant swimming of embryos, remain an esthetic pleasure even for the eyes of seasoned investigators. But sea urchin eggs have other, more practical, advantages: they lend themselves to surgical operation without difficulty and they heal perfectly; they can be obtained in very large amounts and represent thus an extremely favorable material for biochemists and molecular embryologists. It is not surprising that, in view of these exceptional advantages, sea urchin eggs have attracted the interest of innumerable biologists since O. HERTWIG discovered the fusion of the pronuclei (amphimixy), in Paracentrotus lividus, almost a century ago. The purpose of the present book is to present, in a complete and orderly fashion, the enormous amount of information which has been gathered, in the course of a hun dred years of sea urchin embryology. JOSEPH NEEDHAM, in 1930, was still able to present all that was known, at that time, on the biochemistry of all possible species of developing eggs and embryos in his famous "Chemical Embryology" (Cambridge University Press) . It would no longer be possible for one man to write a modern version of what was a "Bible" for the young embryologists of forty years ago.
