Book Description
Up-to-date meeting report of the Else Kr ner-Fresenius Symposium on Adult Stem Cell Aging Adult stem cells are present in most postnatal tissues of mammals. Tissues with high rates of cell turnover depend on the functional capacity of stem cells for lifelong maintenance of tissue homeostasis. Adult stem cells are also required for the regeneration of tissues in response to injury as in, for example, the regeneration of skeletal muscle. In addition to its function in tissue homeostasis and regeneration, adult stem cells can represent the cell type of origin of various types of cancers including leukemia and colorectal cancer. Stem cells are the most long-lived cells in the proliferative compartment of mammalian tissues. Therefore, stem cells have an increased risk of acquiring mutations that could ultimately lead to the transformation of tissue stem cells. This publication presents the current knowledge in the field of stem cell aging, which was discussed at the Else Kr ner-Fresenius Symposium on Advances in Stem Cell Aging in 2011. It will be of special interest to scientists working on stem cell research, aging, regeneration, and cancer as well as physicians and scientists specializing in geriatric medicine, internal medicine, and surgery.

Book Description
Stem Cells and Aging covers what is known about the effect of time and age on the basic units of life, which are the corresponding tissue-specific or adult stem cells. Even though the concept of stem cells was introduced nearly a century ago by Alexander Maximow, modern stem-cell research began in 1963 when James Till, Ernest McCullough and Lou Siminovitch established assays to detect hematopoietic stem cells. In fact, given the importance of the aging-associated diseases, scientists have developed a keen interest in understanding the aging process as they attempt to define the role of dysfunctional stem cells in the aging process. With an aging population worldwide, understanding these age-related stem cell changes at a basic biology level and at the level of their influences for regenerative medicine is of interest and importance. There is increasing evidence that the aging process can have much adverse effects on stem cells. In the modern era, one of the emerging fields in treating human diseases is stem cell research, as stem cells have the remarkable potential to treat a wide range of diseases. Nevertheless, understanding the molecular mechanism involved in aging and deterioration of stem cell function is crucial in developing effective new therapies for aging. Serves as an ideal reference to guide investigators toward valuable answers to the problems of our aging population Addresses the effect of time and age on human stem cells Includes chapters from contributors exploring the biology of stem cell aging around the globe

Book Description
The developmental capabilities and therapeutic potential of stem cells are being revealed in studies of cellular signaling mechanisms that regulate their proliferation, differentiation and survival. "Stem Cells: A Cellular Fountain of Youth" reviews the current state of understanding of the molecular mechanisms that regulate embryonic and adult stem cells with an emphasis on how aging and age-related disease impact on these mechanisms. Leading authorities detail the properties and therapeutic potential of embryonic stem cells, and stem cell precursors of blood, nervous and muscle and bone cells. Recent advances in deciphering the environmental signals and intrinsic signal transduction pathways that regulate embryonic stem cells are described, and the potential therapeutic uses of these totipotent cells is considered. Analyses of hematopoietic stem cells during aging suggest an important genetic component to the control of their self-renewing capability which may contribute to determination of lifespan. The contribution of lymphocyte depletion to impaired immune function during aging is considered, as is the potential of hematopoietic cells to form other types of cells including neurons. Several chapters cover the remarkable and rapidly advancing field of neural stem cells. The adult brain contains populations of stem cells capable of forming new neurons and glial cells; the signals that regulate these neural stem cells and the involvement of neurogenesis in normal brain function is described. Because of their potential to replace lost or damaged neurons, there has been intense interest in determining the therapeutic potential of stem cells for the treatment of patients with Parkinson's and Alzheimer's diseases, stroke and traumatic brain and spinal cord injuries. Heart and skeletal muscle contain stem cells and the impact of aging and disease on these stem cell populations and the potential of stem cell therapy to recover function of these organs is reviewed. A final example of the fascinating world of stem cells is a review of the roles of stem cells in bone formation and remodeling. Collectively, this book provides a comprehensive, yet concise, view of stem cell molecular biology in the context of aging and age-related disease. This book will be a valuable reference for graduate students and senior scientists interested in the fascinating world of stem cells and their potential use in the clinic.

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.

Book Description
Over the past decade, significant efforts have been made to develop stem cell-based therapies for difficult to treat diseases. Multipotent mesenchymal stromal cells, also referred to as mesenchymal stem cells (MSCs), appear to hold great promise in regards to a regenerative cell-based therapy for the treatment of these diseases. Currently, more than 200 clinical trials are underway worldwide exploring the use of MSCs for the treatment of a wide range of disorders including bone, cartilage and tendon damage, myocardial infarction, graft-versus-host disease, Crohn’s disease, diabetes, multiple sclerosis, critical limb ischemia and many others. MSCs were first identified by Friendenstein and colleagues as an adherent stromal cell population within the bone marrow with the ability to form clonogenic colonies in vitro. In regards to the basic biology associated with MSCs, there has been tremendous progress towards understanding this cell population’s phenotype and function from a range of tissue sources. Despite enormous progress and an overall increased understanding of MSCs at the molecular and cellular level, several critical questions remain to be answered in regards to the use of these cells in therapeutic applications. Clinically, both autologous and allogenic approaches for the transplantation of MSCs are being explored. Several of the processing steps needed for the clinical application of MSCs, including isolation from various tissues, scalable in vitro expansion, cell banking, dose preparation, quality control parameters, delivery methods and numerous others are being extensively studied. Despite a significant number of ongoing clinical trials, none of the current therapeutic approaches have, at this point, become a standard of care treatment. Although exceptionally promising, the clinical translation of MSC-based therapies is still a work in progress. The extensive number of ongoing clinical trials is expected to provide a clearer path forward for the realization and implementation of MSCs in regenerative medicine. Towards this end, reviews of current clinical trial results and discussions of relevant topics association with the clinical application of MSCs are compiled in this book from some of the leading researchers in this exciting and rapidly advancing field. Although not absolutely all-inclusive, we hope the chapters within this book can promote and enable a better understanding of the translation of MSCs from bench-to-bedside and inspire researchers to further explore this promising and quickly evolving field.

Book Description
There is growing evidence that adult stem cells age. This process can result in alterations in the number and function of stem cells, leading to distinct phenotypic outcomes in different organ systems. This publication provides an outstanding overview of this emerging field.The molecular causes of stem cell aging remain to be defined. Stem cell aging can involve cell-intrinsic as well as cell-extrinsic alterations affecting the stem cell niche or the macroenvironment. Stem cells have a longer life span than other cell populations and retain a capacity to proliferate and differentiate in adult organs. The aging of adult stem cells plays a key role in the decline of organ maintenance and regenerative potential during aging and during the end stage of chronic diseases. In addition, it can contribute to stem cell transformation and carcinogenesis.Molecular Mechanisms of Adult Stem Cell Aging will appeal to scientists working in the fields such as stem cells, aging, regeneration and cancer. This subject matter should be of interest to physicians and scientists specializing in geriatric medicine, internal medicine, and surgery. It is also likely to be an invaluable resource for medical students and biologists who wish to enhance their understanding of molecular and stem cell biology.

Book Description
Aging of somatic stem cells reduces cell function and results in dysfunctional organs and tissues, making it an underlying cause of diseases associated with aging. It might even be the primary cause for age-associated attrition of tissue function in organs that heavily rely on stem cells for maintaining homeostasis, like the skin, blood and intestines. Understanding the molecular and cellular mechanisms involved is critical for developing approaches to attenuate stem cell aging and could pave the way for improved quality of life among the elderly. Written by highly prominent experts in the field, this book presents the current state of knowledge on these mechanisms. It offers insights into stem cell function, explains in detail the mechanisms of stem cell aging in model organisms as well as mammalian systems and describes related diseases and approaches to attenuating stem cell aging or achieving rejuvenation. The book is intended for all scientists and clinicians working with stem cells, aging mechanisms or age-related diseases.
