Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Saving lives versus taking lives: These are the stark terms in which the public regards human embryo research--a battleground of extremes, a war between science and ethics. Such a simplistic dichotomy, encouraged by vociferous opponents of abortion and proponents of medical research, is precisely what Jane Maienschein seeks to counter with this book. Whose View of Life? brings the current debates into sharper focus by examining developments in stem cell research, cloning, and embryology in historical and philosophical context and by exploring legal, social, and ethical issues at the heart of what has become a political controversy. Drawing on her experience as a researcher, teacher, and congressional fellow, Jane Maienschein provides historical and contemporary analysis to aid understanding of the scientific and social forces that got us where we are today. For example, she explains the long-established traditions behind conflicting views of how life begins--at conception or gradually, in the course of development. She prepares us to engage a major question of our day: How are we, as a 21st-century democratic society, to navigate a course that is at the same time respectful of the range of competing views of life, built on the strongest possible basis of scientific knowledge, and still able to respond to the momentous opportunities and challenges presented to us by modern biology? Maienschein's multidisciplinary perspective will provide a starting point for further attempts to answer this question.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Icons of Life tells the engrossing and provocative story of an early twentieth-century undertaking, the Carnegie Institution of Washington's project to collect thousands of embryos for scientific study. Lynn M. Morgan blends social analysis, sleuthing, and humor to trace the history of specimen collecting. In the process, she illuminates how a hundred-year-old scientific endeavor continues to be felt in today's fraught arena of maternal and fetal politics. Until the embryo collecting project-which she follows from the Johns Hopkins anatomy department, through Baltimore foundling homes, and all the way to China-most people had no idea what human embryos looked like. But by the 1950s, modern citizens saw in embryos an image of "ourselves unborn," and embryology had developed a biologically based story about how we came to be. Morgan explains how dead specimens paradoxically became icons of life, how embryos were generated as social artifacts separate from pregnant women, and how a fetus thwarted Gertrude Stein's medical career. By resurrecting a nearly forgotten scientific project, Morgan sheds light on the roots of a modern origin story and raises the still controversial issue of how we decide what embryos mean.
Download or read book Stem Cells and the Future of Regenerative Medicine written by Institute of Medicine and published by National Academies Press. This book was released on 2002-01-25 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent scientific breakthroughs, celebrity patient advocates, and conflicting religious beliefs have come together to bring the state of stem cell researchâ€"specifically embryonic stem cell researchâ€"into the political crosshairs. President Bush's watershed policy statement allows federal funding for embryonic stem cell research but only on a limited number of stem cell lines. Millions of Americans could be affected by the continuing political debate among policymakers and the public. Stem Cells and the Future of Regenerative Medicine provides a deeper exploration of the biological, ethical, and funding questions prompted by the therapeutic potential of undifferentiated human cells. In terms accessible to lay readers, the book summarizes what we know about adult and embryonic stem cells and discusses how to go about the transition from mouse studies to research that has therapeutic implications for people. Perhaps most important, Stem Cells and the Future of Regenerative Medicine also provides an overview of the moral and ethical problems that arise from the use of embryonic stem cells. This timely book compares the impact of public and private research funding and discusses approaches to appropriate research oversight. Based on the insights of leading scientists, ethicists, and other authorities, the book offers authoritative recommendations regarding the use of existing stem cell lines versus new lines in research, the important role of the federal government in this field of research, and other fundamental issues.

Available in PDF, EPUB and Kindle. Book excerpt: Too tiny to see with the naked eye, the human embryo was just a hypothesis until the microscope made observation of embryonic development possible. This changed forever our view of the minuscule cluster of cells that looms large in questions about the meaning of life. Embryos under the Microscope examines how our scientific understanding of the embryo has evolved from the earliest speculations of natural philosophers to today’s biological engineering, with its many prospects for life-enhancing therapies. Jane Maienschein shows that research on embryos has always revealed possibilities that appear promising to some but deeply frightening to others, and she makes a persuasive case that public understanding must be informed by up-to-date scientific findings. Direct observation of embryos greatly expanded knowledge but also led to disagreements over what investigators were seeing. Biologists confirmed that embryos are living organisms undergoing rapid change and are not in any sense functioning persons. They do not feel pain or have any capacity to think until very late stages of fetal development. New information about DNA led to discoveries about embryonic regulation of genetic inheritance, as well as evolutionary relationships among species. Scientists have learned how to manipulate embryos in the lab, taking them apart, reconstructing them, and even synthesizing—practically from scratch—cells, body parts, and maybe someday entire embryos. Showing how we have learned what we now know about the biology of embryos, Maienschein changes our view of what it means to be alive.

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 Life Before Birth The Moral and Legal Status of Embryos and Fetuses written by Albany Bonnie Steinbock Associate Professor of Philosophy & Public Policy State University of New York and published by Oxford University Press, USA. This book was released on 1992-07-23 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardly a day passes without newspaper coverage of some new development regarding prenatal life. The abortion debate continues to rage, but other examples abound: forced Caesareans; prosecutions of women for drug use during pregnancy; fetal protection policies; the use of fetal tissue for transplantation; embryo research; and the disposition of frozen embryos. All of these issues raise the question of the moral status of the unborn: are embryos and fetuses part of the pregnant woman or are they persons? Are they sources of tissue, research tools, or are they pre-born children? Different conceptions of the unborn prevail in different contexts, giving rise to the charge of inconsistency. For example, women have been criminally charged with abusing their fetuses by using drugs during pregnancy, even though abortion--which pro-lifers call the ultimate child abuse--is legal. The legalization of abortion itself was based in part on the unborn's never having been recognized in law as a full legal person. Yet fetuses have been considered as persons for the purposes of insurance coverage, wrongful death suits, and vehicular homicide. This book provides a framework for thinking clearly and coherently about the unborn. The first chapter elaborates the book's basic idea, that all and only beings who have interests have moral standing, and only beings who possess conscious awareness have interests. This thesis, which is called "the interest view," raises issues of considerable philosophical complexity, but is presented in language non-philosophers will be able to understand. Subsequent chapters apply the interest view, and explore the moral and legal aspects of a wide range of issues, including abortion, the legal status of the fetus outside abortion, maternal-fetal conflict, fetal research, and the use and disposition of extracorporeal embryos resulting from the new reproductive technologies. The philosophical discussion is enlivened by examples and actual cases which immediately catch, and sustain, the reader's interest. Written in a lively style, Life Before Birth: The Moral and Legal Status of Embryos and Fetuses is a timely and important work that enables us to resolve contradictions in our current thinking about the unborn, and to approach new issues in a clear and rational manner.
Download or read book Life Before Birth written by Bonnie Steinbock and published by Oxford University Press. This book was released on 2011-07-11 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life Before Birth provides a coherent framework for addressing bioethical issues in which the moral status of embryos and fetuses is relevant. It is based on the "interest view" which ascribes moral standing to beings with interests, and connects the possession of interests with the capacity for conscious awareness or sentience. The theoretical framework is applied to ethical and legal topics, including abortion, prenatal torts, wrongful life, the crime of feticide, substance abuse by pregnant women, compulsory cesareans, assisted reproduction, and stem cell research. Along the way, difficult philosophical problems, such as identity and the non-identity problem are thoroughly explored. The book will be of interest not only to philosophers, but also physicians, lawyers, policy makers, and anyone perplexed by the many difficulties surrounding the unborn. "Bonnie Steinbock's excellent book is . . . consistent, thoroughgoing, and intelligible." --Nature "Steinbock's book is valuable for all interested in the ethical/legal issues surrounding abortion, prenatal injury and liability, maternal-fetal conflict, and fetal/embryo research. The author provides an excellent historical overview of these issues, but she also addresses the issues from the stance of a particular theory of moral status, namely, interest theory. This gives coherence to her discussion as well as allowing testing of the viability of interest theory." --Choice "A focused, lucid, analytically fine-grained discussion of a wide variety of problems. . . extremely useful as a survey of the current state of the debate." --Religious Studies Review "Merits serious consideration by physicians. Steinbock's interests-based approach treats all questions as open -- another and most welcome breath of fresh air." -New England Journal of Medicine "An extremely valuable contribution to the literature. The author carefully identifies the many bioethical issues to which the status of embryos and fetuses is relevant....She thoroughly reviews the extensive medical, bioethical, and legal literature on all of these issues, offering well-developed critiques of many standard positions. She articulates and thoughtfully defends interesting positions on all of theses topics. Anyone with an interest in these issues will learn a great deal from her knowledgeable and judicious treatment of them." -- The Journal of Clinical Ethics
