Human Fetal Tissue Transplantation


Book Description

Many diseases earlier considered to be incurable are now being treated with modern innovations involving fetal tissue transplants and stem cells derived from fetal tissues. Fetal tissues are the richest source of fetal stem cells as well as other varying states of differentiated cells and support or stromal cells. The activity of such stem cells is at their peak provided they are given the correct niche. Stem cells, as we know, are immortal cells with the capacity to regenerate into any kind of differentiated cell as per niche-guidance. As such, fetal tissues have the potential capacity to mend, regenerate and repair damaged cells or tissues in adults, when directly transplanted to the site of injury, or even when transplanted in some other site, because it may have a homing capacity to migrate to the site of the specific injured organ. This is a new area of translational research and needs to be highlighted because of its immense potential. This book will bring together the new work of prominent medical scientists and clinicians who are conducting pioneering research in human fetal tissue transplantation. This will include direct transplant of healthy fetal tissue into mature patients as well as in hosts with genetic diseases. Transplant techniques, donor-host interaction, cell and tissue storage, ethical and legal issues, are some of the many matters which the book will deal with.







Stem Cells and the Future of Regenerative Medicine


Book Description

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.

Society's Choices


Book Description

Breakthroughs in biomedicine often lead to new life-giving treatments but may also raise troubling, even life-and-death, quandaries. Society's Choices discusses ways for people to handle today's bioethics issues in the context of America's unique history and cultureâ€"and from the perspectives of various interest groups. The book explores how Americans have grappled with specific aspects of bioethics through commission deliberations, programs by organizations, and other mechanisms and identifies criteria for evaluating the outcomes of these efforts. The committee offers recommendations on the role of government and professional societies, the function of commissions and institutional review boards, and bioethics in health professional education and research. The volume includes a series of 12 superb background papers on public moral discourse, mechanisms for handling social and ethical dilemmas, and other specific areas of controversy by well-known experts Ronald Bayer, Martin Benjamin, Dan W. Brock, Baruch A. Brody, H. Alta Charo, Lawrence Gostin, Bradford H. Gray, Kathi E. Hanna, Elizabeth Heitman, Thomas Nagel, Steven Shapin, and Charles M. Swezey.




Humanized Mice for HIV Research


Book Description

Over the last several years the field of humanized mice has matured and developed into an essential component of translational research for HIV/AIDS. Humanized mice serve both as vehicles for discovery and as highly sophisticated platforms for biomedical research. In addition, humanized mice have demonstrated outstanding potential for the investigation of critical aspects of the infection and pathogenesis of the hepatitis and herpes viruses, as well as highly relevant microbial infections such as tuberculosis and malaria. Humanized Mice for HIV Research provides a comprehensive presentation of the history, evolution, applications, and current state of the art of this unique animal model. An expansion of twelve review articles that were published in Humanized Mice by Springer in 2008 (Eds: Nomura T, Watanabe T, Habu S), this book expertly captures the outstanding progress that has been made in the development, improvement, implementation, and validation of humanized mouse models. The first two parts of this book cover the basics of human-to-mouse xenotransplantation biology, and provide critical information about human immune cell development and function based on individual models created from different immunodeficient strains of mice. The third and fourth parts investigate HIV-1 biology, including different routes of transmission, prevention, treatment, pathogenesis, and the development of adaptive immunity in humanized mice. The fifth part shows the broad applicability of humanized mice for therapeutic development, from long-acting antiretroviral combinations to genetic manipulations with human cells and cell-based approaches. The sixth part includes liver tissue engineering and the expansion of humanized mice for many other human cell-tropic pathogens.

Xenotransplantation


Book Description

Xenotransplantation involves the transplantation of cells, tissues, and whole organs from one species to another. Interest in animal-to-human xenotransplants has been spurred by the continuing shortage of donated human organs and by advances in knowledge concerning the biology of organ and tissue rejection. The scientific advances and promise, however, raise complex questions that must be addressed. This book considers the scientific and medical feasibility of xenotransplantation and explores the ethical and public policy issues surrounding the possibility of renewed clinical trials. The volume focuses on the science base of xenotransplantation, public health risks of infectious disease transmission, and ethical and public policy issues, including the views of patients and their families.




Cellular Transplantation


Book Description

There have been tremendous strides in cellular transplantation in recent years, leading to accepted practice for the treatment of certain diseases, and use for many others in trial phases. The long history of cellular transplantation, or the transfer of cells from one organism or region of the body to another, has been revolutionized by advances in stem cell research, as well as developments in gene therapy. Cellular Transplants: From Lab to Clinic provides a thorough foundation of the basic science underpinning this exciting field, expert overviews of the state-of-the-art, and detailed description of clinical success stories to date, as well as insights into the road ahead. As highlighted by this timely and authoritative survey, scale-up technologies and whole organ transplantation are among the hurdles representing the next frontier. The contents are organized into four main sections, with the first covering basic biology, including transplant immunology, the use of immunosuppressive drugs, stem cell biology, and the development of donor animals for transplantation. The next part looks at peripheral and reconstructive applications, followed by a section devoted to transplantation for diseases of the central nervous system. The last part presents efforts to address the key challenges ahead, such as identifying novel transplantable cells and integrating biomaterials and nanotechnology with cell matrices. - Provides detailed description of clinical trials in cell transplantation - Review of current therapeutic approaches - Coverage of the broad range of diseases addressed by cell therapeutics - Discussion of stem cell biology and its role in transplantation




The Concept of Moral Consensus


Book Description

The demand for consensus arises due to its absence. For each opinion held there will be another to counter it, and for each approach to problem solving an alternative will be suggested. Focusing on the bioethical problems surrounding new technical interventions in human reproduction, 15 authors try to examine the meaning, importance and feasibility of consensus. The very different perspectives from the philosophers, physicians, lawyers, theologians, politicians and sociologists contributing to this topic reflect on the difficulties and complexity of moral decision making, offer views on the problem of why decision making does not take place more harmoniously and asks if there can be any hope of a solution in a world where the discipline of contemporary ethics is characterised by a vast diversity - or chaos - of heterogenous theories and concurring approaches. This book is intended for philosophers, physicians, ethicists and everyone involved in moral decision making, to shape his or her understanding of this process and to help him or her to reflect on the concept of consensus.
