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
This volume provides insight into the pivotal roles of stem cells, exosomes and other microvesicles in biofunction and molecular mechanisms and their therapeutic potential in translational nanomedicine. It further highlights evidence from recent studies as to how stem cell derived exosomes and microRNAs may restore and maintain tissue homeostasis, enable cells to recover critical cellular functions and begin repair regeneration. These early studies in animal models of aging also show evidence of improved immune, cardiovascular and cognitive functions as well as improved health span and life span. The use of exosomes from body fluids to define specific biomarkers for various tumors may also clear the path to patient-targeted treatments by developing exosome-derived microRNA based cancer therapeutics. It is essential reading for graduate students, research fellow and biomedical researchers in academia or the pharmaceutical or biotech industries.

Book Description
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 Kröner-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
This book is dedicated to the great scientist and outstanding individual Nikolay Wladimirovich Timofeeff-Ressovsky. The book brings together a number of brief stories/essays about Timofeeff-Ressovsky including “Stories told by himself”, and scientific chapters addressing his major research areas: genetics, radiobiology, radiation ecology and epidemiology, and evolution. Timofeeff-Ressovsky contributed to several fields of biology and established new directions of scientific research. He often repeated the phrase, which would later become famous: “Science should not be approached with the ferocity of wild animals”. In keeping with that philosophy, the issues discussed here are still open. Each scientific part starts with a current review; the chapters present leading scientific schools and views. The main theme discussed in the genetics part is mutation variability in the context of linear (replication, transcription, translation) and conformational template processes, and its dependence on phylogenetic group. In turn, the radiobiology chapters focus on the reorganization of DNA, cell, and population variability under low-dose irradiation, sparking indirect processes and adaptive response. The radiation ecology and epidemiology parts present data on the consequences of nuclear plants and related accidents for ecological systems and human beings. Here some approaches to estimating radiation risks are also offered. Evolution laws are demonstrated in the genomic universe, plant-microbe symbiosis, stabilizing and destabilizing (directional) selection. The last essay demonstrates the principles of organization operating in local animal populations, which are approached as social organisms of complex systemic nature. The chapter 'Radiation-Induced Aging and Genetic Instability of Mesenchymal Stem Cells: An Issue for Late Health Effects?' is available open access under a CC BY 4.0 license.

Book Description
Stem Cell Biology in Health and Disease presents an up-to-date overview about the dual role of stem cells in health and disease. The Editors have drawn together an international team of experts providing chapters which, in this fully-illustrated volume, discuss: - the controversial debate on the great expectations concerning stem cell based regeneration therapies raised by the pluripotency of various stem cells. - the advantages and concerns about embryonic stem cells (ES cells), induced pluripotent stem cells (iPS cells) and adult stem cells, such as bone marrow-derived stem cells (BMDCs). - the type of stem cells, which has become of interest in the past decade, namely so-called cancer stem cells (CSCs). CSCs are now in the focus of cancer research since the eradication of tumour initiating cells would raise the changes of definitely cure cancer. Professor Dittmar and Professor Zänker have edited a must-read book for researchers and professionals working in the field of regenerative medicine and/or cancer.

Book Description
Stem Cells: An Insider's Guide is an exciting new book that takes readers inside the world of stem cells guided by international stem cell expert, Dr. Paul Knoepfler. Stem cells are catalyzing a revolution in medicine. The book also tackles the exciting and hotly debated area of stem cell treatments that are capturing the public's imagination. In the future they may also transform how we age and reproduce. However, there are serious risks and ethical challenges, too. The author's goal with this insider's guide is to give readers the information needed to distinguish between the ubiquitous hype and legitimate hope found throughout the stem cell world. The book answers the most common questions that people have about stem cells. Can stem cells help my family with a serious medical problem such as Alzheimer's, Multiple Sclerosis, or Autism? Are such treatments safe? Can stem cells make me look younger or even literally stay physically young? These questions and many more are answered here.A number of ethical issues related to stem cells that spark debates are discussed, including risky treatments, cloning and embryonic stem cells. The author breaks new ground in a number of ways such as by suggesting reforms to the FDA, providing a new theory of aging based on stem cells, and including a revolutionary Stem Cell Patient Bill of Rights. More generally, the book is your guide to where the stem cell field will be in the near future as well as a thoughtful perspective on how stem cell therapies will ultimately change your life and our world.

Book Description
This is comprehensive overview of a vital area of scientific enquiry, which covers a broad spectrum of issues. With contributions from some of the key researchers in the field, Adult Stem Cells: Biology and Methods of Analysis offers readers a historical perspective as well as unique insights into cutting-edge thoughts. The volume contextualizes the recent discovery of stem/progenitor cell populations resident in many adult tissues and organs. It confronts the complexities scientists face in trying to validate these cells, while it also describes and critically evaluates the methods currently used to assess stem cell self-renewal. The chapters also seek to distinguish this process from other aspects of cell survival, such as the regulation of life span, senescence, and immortalization at a molecular level. The monograph begins with a section that examine the basic biology of adult stem cells, including chapters on the emerging role of microRNAs in regulating their fate and the molecular mechanisms that govern their self-renewal, the book moves on to analyze the varying methodologies employed in characterizing these elusive elements of our genetic make-up. The second section details in-vivo lineage tracing of tissue-specific stem cells, explores the neural stem cell paradigm, and considers the function of ABC transporters and aldehyde dehydrogenase in adult stem-cell biology. The final section shifts the focus to the life-span regulation and immortalization and features a chapter on the cancer stem cell paradigm. This is an authoritative volume on one of the frontiers of genetic research, and will serve as a valuable resource, not just for established scientists but also for those now entering the field of stem cell biology.
