The International Life Sciences Institute (ILSI) was estab lished in 1978 to stimulate and support scientific research and educational programs related to nutrition, toxicology, and food safety, and to encourage cooperation in these programs among scientists in universities, industry, and government agencies to assist in the resolution of health and safety issues. To supplement and enhance these efforts, ILSI has made a major commitment to supporting programs to harmon ize toxicologic testing, to advance a more uniform inter pretation of bioassay results worldwide, to promote a common understanding of lesion classifications, and to encourage wide discussion of these topics among scien tists. The Monographs on the Pathology of Laboratory Ani mals are designed to facilitate communication among those involved in the safety testing of foods, drugs, and chemicals. The complete set will cover all organ systems and is intended for use by pathologists, toxicologists, and others concerned with evaluating toxicity and carcinogen icity studies. The international nature of the project - as reflected in the composition of the editorial board and the diversity of the authors and editors - strengthens our ex pectations that understanding and cooperation will be im proved worldwide through the series. Alex Malaspina President International Life Sciences Institute Preface This book, on the hemopoietic system, is the eighth volume of a set prepared under the sponsorship of the International Life Sciences In stitute (ILSI).

A Practical Guide to the Histology of the Mouse provides a full-colour atlas of mouse histology. Mouse models of disease are used extensively in biomedical research with many hundreds of new models being generated each year. Complete phenotypic analysis of all of these models can benefit from histologic review of the tissues. This book is aimed at veterinary and medical pathologists who are unfamiliar with mouse tissues and scientists who wish to evaluate their own mouse models. It provides practical guidance on the collection, sampling and analysis of mouse tissue samples in order to maximize the information that can be gained from these tissues. As well as illustrating the normal microscopic anatomy of the mouse, the book also describes and explains the common anatomic variations, artefacts associated with tissue collection and background lesions to help the scientist to distinguish these changes from experimentally- induced lesions. This will be an essential bench-side companion for researchers and practitioners looking for an accessible and well-illustrated guide to mouse pathology. Written by experienced pathologists and specifically tailored to the needs of scientists and histologists Full colour throughout Provides advice on sampling tissues, necropsy and recording data Includes common anatomic variations, background lesions and artefacts which will help non-experts understand whether histologic variations seen are part of the normal background or related to their experimental manipulation

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.

This monograph summarizes the large amount of experimental data accumulated during many years of studying the functions of the blood system and its regulatory mechanisms under the action of diverse morbific factors within the models of pathological processes (e.g. immobilization stress, blood loss, inflammation, cytostatic and radiation myelosuppressions, experimental encephalopathies, neuroses, and spontaneous leucosis). These data are is analyzed with the understanding that hematopoietic tissue is an integrated system that can react to the challenges of both the internal and external environments. This analysis helped develop the theory of hematopoiesis control describing the regularities in the work of basic subdivisions of the hematopoietic tissue under normal and pathological conditions, as well as the performance and interaction of the local and long-ranged control systems. The monograph is recommended for Physiologists, Pathophysiologists, Hematologists, Oncologists, Pharmacologists and other professionals.

This book collects articles on the biology of hematopoietic stem cells during embryonic development, reporting on fly, fish, avian and mammalian models. The text invites a comparative overview of hematopoietic stem cell generation in the different classes, emphasizing conserved trends in development. The book reviews current knowledge on human hematopoietic development and discusses recent breakthroughs of relevance to both researchers and clinicians.

During the past 20 years, celJ biology has made immense strides which have completely transformed the time-honored morphological hematology of yesterday. This progress is primarily due to the introduction of new techniques which allow functional rather than anatomic studies: labeling techniques have made possible the study of celJ kinetics from birth to death of a celJ: culture techniques (both in vivo and in vitro) have made it possible to establish the progeny of certain stern celJs, their growth poten tiaL and the mechanisms of their regulation. The results have been so impressive and have so aroused the enthusiasm 01' young hematologists that it has become fashionable in so me quarters to consider the microscope an "extinct instrument" and morphology littlc more than an outmoded (if agreeable) pastime of little scientific interest. One of the consequences is the wish of some investigators to study cytology without the aid of their eyes. The present book makes us realize once more that morphology is the science of structure and shape and that its aim is not to colJect pictures but to understand them. It is true that microscopic observation, even when made with the electron microscope, cannot by itself answer some basic questions of celJ biology. However, the hematologist who uses only a single technique is like a person who would describe the world from the point of view of a single sensory organ and would refuse the aid of the others.
