This 4th edition of the "Mouse Manual"-Manipulating the Mouse Embryo-appears 28 years after the first edition and once again is the definitive reference source on mouse development, transgenesis techniques, and molecular biology. Authors Richard Behringer, Marina Gertsenstein, Kristina Nagy, and Andras Nagy-pre-emininent leaders in their fields-have reorganized and updated this edition to include new information and protocols on: * assisted reproduction techniques for sperm and embryo cryopreservation * generation of induced pluripotent stem cells * isolation, generation, and transplantation of spermatogonial stem cell lines * in utero electroporation of gene constructs into post- implantation embryos * vibratome sectioning of live and fixed tissues for imaging thick tissue sections * whole-mount fluorescent staining methods for three-dimensional visualization. Techniques regarding recombinant DNA technology and mouse embryonic development from the previous editions have been updated and recast, as has the wealth of information on mouse laboratory strains, mouse housing and breeding, surgical procedures, assisted reproduction, handling of embryos, and micromanipulation setups. The first edition of Manipulating the Mouse Embryo appeared in 1986 as an outgrowth of Cold Spring Harbor Laboratory courses on the molecular embryology of the mouse held in the early 1980s, and authors of the first two editions included Brigid Hogan, Rosa Beddington, Frank Costantini, and Liz Lacy. Mouse embryo manipulation techniques have developed exponentially since the first edition, but then, as now, Manipulating the Mouse Embryo remains the essential practical and theoretical guide for anyone working with mice-students, lab technicians, and investigators.

Among the many applications of stem cell research are nervous system diseases, diabetes, heart disease, autoimmune diseases as well as Parkinson's disease, end-stage kidney disease, liver failure, cancer, spinal cord injury, multiple sclerosis, Parkinson's disease, and Alzheimer's disease. Stem cells are self-renewing, unspecialised cells that can give rise to multiple types all of specialised cells of the body. Stem cell research also involves complex ethical and legal considerations since they involve adult, foetal tissue and embryonic sources. This book brings together leading research from throughout the world with particular focus on stem cells and cancer research.

This title contains a book and CD. The brain has a number of nerve cells estimated at a magnitude of 10 to 100 billion, and 1014 to 1015 synapses, and therefore is the most complex organ of the human body. During fetal development the foundations of the brain are laid as billions of neurons form appropriate connections and patterns. In the adult mammalian brain, most neurons are post-mitotic, and therefore at risk for irreversible damage. As we age, atrophy of the brain occurs. As brain weight declines the volume of the brain in the 8th decade is reduced by 6 per cent -10 per cent versus the third decade, and neuronal loss occurs, up to 10,000 to 100,000 neurons are lost per day, though this estimation is being revised downward with the advance of more sophisticated measurements.

New research has shown that children exposed to cocaine before birth are at risk of learning and behavioral problems. Such problems have broad implications for education, social welfare, and criminal justice in the United States. However, there are numerous opportunities to minimize prenatal cocaine exposure and its impacts and thus to enhance the well-being of women and their children. This report, a collaborative effort of the RAND Drug Policy Research Center and the New York Academy of Sciences, presents an overview of the current state of knowledge regarding the effects of cocaine on the developing brain and offers policy considerations for addressing the issues that arise from cocaine use by pregnant women. The report discusses three prevention strategies: primary prevention (preventing substance use before and during pregnancy); secondary prevention (identifying pregnant women who use drugs and minimizing their drug use); and tertiary prevention (reducing the adverse consequences of substance exposure in children who were exposed in utero). In addition, the report presents a number of areas where more research is needed and offers a rationale for making more resources available for women and children affected by cocaine. (JD)

This Basic Concepts title sheds light on the most elusive concepts in embryology and does so in a concise, lively manner. The level of detail is geared directly to that which is required by students in a way which esily accesses the most relevant information. The book utilizes jargon-free language and innovative teaching techniques to promote an understanding of concepts--not just the rote memorization of facts. To further enhance comprehension, text and illustrations accompany each other on the same or facing pages.

Long regarded as biological waste, the placenta is gaining momentum as a viable product for clinical use. Due to their unique properties, placental cells and derivatives show great promise in curing various diseases. Utilizing contributions from world-renowned experts, Placenta: The Tree of Life considers the therapeutic potential of these cells. It examines new stem cell-based strategies and highlights recent studies that advance the range of treatment for a number of illnesses. Emphasizing the potential research and therapeutic use of stem cells, the book discusses the development, structure, and functions of the human placenta. It introduces overall aspects of the immune system, explains some of the immune mechanisms during pregnancy, and shows the role of the placenta in these mechanisms. Current scientific research is presented that focuses on the mechanisms of action underlying the therapeutic benefit of cells isolated from different placental regions. An exhaustive examination, this pivotal work: Considers how perinatal cells may represent an important source for cell therapy approaches in the near future, in both human and veterinary medicine Describes the clinical potential of placenta-derived cells in regenerative medicine-specifically in neurological disorders, metabolic liver diseases, inflammatory diseases, and autoimmune diseases Explains how cells isolated from different placental tissues share basic properties Placenta: The Tree of Life summarizes the advantages of perinatal tissue as a source of cells with therapeutic potential and is designed for use in the study of genetics, stem cell science, placental function, reproductive biology, regenerative medicine, and related fields.

This title includes a number of Open Access chapters. Embryology is the study of embryos. It is the branch of biological science that deals with the formation and early development of an individual organism, from fertilization of the egg (ovum) to birth. This collection includes articles on some of the most important topics in embryology today, such as cryopreservation of human embryos, in vitro generation of neurons from embryonic stem cells, embryonic transfer, transcriptional profiling, and more.

Kinetic models are becoming standard tools in the research of biological systems. They are used to represent hypotheses, analyze data, and design experiments to maximize the information obtained from a study. Kinetic Models of Trace Element and Mineral Metabolism During Development describes models for calcium, chromium, copper, iron, iodide, lead, mercury, selenium, zinc, and others in health and disease.

The complex but fascinating field of embryology is presented in this easy-to-understand Thieme Flexibook, complete with 176 color plates. Since the information relevant to medical students is separated from that needed by biologists, both can learn in a focused and time-saving manner. The overview at the beginning of each chapter is also an excellent aid to students. Physicians, biologists and students can delve into any number of topics: from the basics of reproductive biology to general embryology, including the "hot topics" related to cellular and molecular biology.
