Available in PDF, EPUB and Kindle. Book excerpt: The Human Embryo in vitro explores the ways in which UK law engages with embryonic processes under the Human Fertilisation and Embryology Act 1990 (as amended), the intellectual basis of which has not been reconsidered for almost thirty years. McMillan argues that in regulating 'the embryo' – that is, a processual liminal entity in itself - the law is regulating for uncertainty. This book offers a fuller understanding of how complex biological processes of development and growth can be better aligned with a legal framework that purports to pay respect to the embryo while also allowing its destruction. To do so it employs an anthropological concept, liminality, which is itself concerned with revealing the dynamics of process. The implications of this for contemporary regulation of artificial reproduction are fully explored, and recommendations are offered for international regimes on how they can better align biological reality with social policy and law.
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.

Download or read book Examining the State of the Science of Mammalian Embryo Model Systems written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2020-08-31 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the recent advances in embryo modeling techniques, and at the request of the Office of Science Policy in the Office of the Director at the National Institutes of Health, the National Academies of Sciences, Engineering, hosted a 1-day public workshop that would explore the state of the science of mammalian embryo model systems. The workshop, which took place on January 17, 2020, featured a combination of presentations, panels, and general discussions, during which panelists and participants offered a broad range of perspectives. Participants considered whether embryo model systems - especially those that use nonhuman primate cells - can be used to predict the function of systems made with human cells. Presentations provided an overview of the current state of the science of in vitro development of human trophoblast. This publication summarizes the presentation and discussion of the workshop.
Download or read book The Anatomy of the Human Embryo written by Gerd Steding and published by Karger Medical and Scientific Publishers. This book was released on 2009 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present anatomical atlas concentrates on the early weeks of prenatal development of the human embryo. It comprises more than 800 scanning electron-microscopic pictures of specimens of exclusively human embryos. The three-dimensional appearing illustrations show the development of the external form of the face, neck, trunk and limbs. Besides, the brain and the viscera of the head, neck, thorax, abdomen and pelvis all dissected into layers are represented in their position and spatial form. The juxtaposition of pictures of temporally close developmental stages reveals the changes in the form of the organs. Photographs of the same organic system are usually shown at the same magnification and clearly demonstrate the growth process. Simple outline drawings provided with the principal nomenclature facilitate the orientation within the specimens. A brief introduction to each chapter explains the most significant developmental steps depicted. This atlas is of great interest not only to anatomists, embryologists, histologists and developmental biologists, but also to biologists, biochemists and geneticists. Moreover, it serves as a valuable reference book for clinicians such as gynecologists, obstetricians, pediatric surgeons and pediatric cardiologists.
Download or read book Icons of Life written by Lynn Morgan and published by Univ of California Press. This book was released on 2009-09-09 with total page 329 pages. 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 Experiments in Democracy written by Benjamin J. Hurlbut and published by Columbia University Press. This book was released on 2017-01-31 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human embryo research touches upon strongly felt moral convictions, and it raises such deep questions about the promise and perils of scientific progress that debate over its development has become a moral and political imperative. From in vitro fertilization to embryonic stem cell research, cloning, and gene editing, Americans have repeatedly struggled with how to define the moral status of the human embryo, whether to limit its experimental uses, and how to contend with sharply divided public moral perspectives on governing science. Experiments in Democracy presents a history of American debates over human embryo research from the late 1960s to the present, exploring their crucial role in shaping norms, practices, and institutions of deliberation governing the ethical challenges of modern bioscience. J. Benjamin Hurlbut details how scientists, bioethicists, policymakers, and other public figures have attempted to answer a question of great consequence: how should the public reason about aspects of science and technology that effect fundamental dimensions of human life? Through a study of one of the most significant science policy controversies in the history of the United States, Experiments in Democracy paints a portrait of the complex relationship between science and democracy, and of U.S. society's evolving approaches to evaluating and governing science's most challenging breakthroughs.
Download or read book Vascular Development written by Derek J. Chadwick and published by John Wiley & Sons. This book was released on 2007-08-20 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The formation of blood vessels is an essential aspect of embryogenesis in vertebrates. It is a central feature of numerous post-embryonic processes, including tissue and organ growth and regeneration. It is also part of the pathology of tumour formation and certain inflammatory conditions. In recent years, comprehension of the molecular genetics of blood vessel formation has progressed enormously and studies in vertebrate model systems, especially the mouse and the zebrafish, have identified a common set of molecules and processes that are conserved throughout vertebrate embryogenesis while, in addition, highlighting aspects that may differ between different animal groups. The discovery in the past decade of the crucial role of new blood vessel formation for the development of cancers has generated great interest in angiogenesis (the formation of new blood vessels from pre-existing ones), with its major implications for potential cancer-control strategies. In addition, there are numerous situations where therapeutic treatments either require or would be assisted by vasculogenesis (the de novo formation of blood vessels). In particular, post-stroke therapies could include treatments that stimulate neovascularization of the affected tissues. The development of such treatments, however, requires thoroughly understanding the developmental properties of endothelial cells and the basic biology of blood vessel formation. While there are many books on angiogenesis, this unique book focuses on exactly this basic biology and explores blood vessel formation in connection with tissue development in a range of animal models. It includes detailed discussions of relevant cell biology, genetics and embryogenesis of blood vessel formation and presents insights into the cross-talk between developing blood vessels and other tissues. With contributions from vascular biologists, cell biologists and developmental biologists, a comprehensive and highly interdisciplinary volume is the outcome.

Download or read book Exploring the Biological Contributions to Human Health written by Institute of Medicine and published by National Academies Press. This book was released on 2001-07-02 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.
Download or read book Untangling Twinning written by Maureen L. Condic and published by University of Notre Dame Pess. This book was released on 2020-02-28 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists and philosophers have long struggled to answer the questions of when human life begins and when human life has inherent value. The phenomenon of identical (monozygotic) twinning presents a significant challenge to the view that human life and human personhood begin at conception. The fact that a single embryo can split to generate two (or more) genetically identical embryos seems to defy the notion that prior to splitting an embryo can be a single human individual. In Untangling Twinning, Maureen Condic looks at the questions raised by human twinning based on a unique synthesis of molecular developmental biology and Aristotelian philosophy. She begins with a brief historical analysis of the current scientific perspective on the embryo and proceeds to address the major philosophic and scientific concerns regarding human twinning and embryo fusion: Is the embryo one human or two (or even more)? Does the original embryo die, and if not, which of the twins is the original? Who are the parents of the twins? What do twins, chimeras, cloning, and asexual reproduction in humans mean? And what does the science of human embryology say about human ensoulment, human individuality, and human value? Condic's original approach makes a unique contribution to the discussion of human value and human individuality, and offers a clear, evidence-based resolution to questions raised by human twinning. The book is written for students and scholars of bioethics, scientists, theologians, and attorneys who are involved in questions surrounding the human embryo.
