Stem Cell Microenvironments And Beyond

This book discusses the main stem cell niches under distinct pathophysiological conditions. The role of tissue microenvironments in stem cell regulation, as well as modern methodologies and new techniques for the identification and characterization of stem cell niches, are discussed by leading experts in the field. Chapters describe the major components of various stem cell microenvironments, such as cellular components, soluble factors, cell-cell interactions, extra-cellular matrix proteins, and physical forces. Stem Cell Microenvironments and Beyond is part of the highly successful Advances in Experimental Medicine and Biology series. It is essential reading for graduate students and researchers in the field of stem cells or cell biology as well as clinicians.

Stem cells hold great promise for cell therapy, tissue engineering, regenerative medicine and pharmaceutical and biotechnological applications. This book highlights the potency of stem cells, their property of self-renewal and their ability to differentiate into different cell lineages. It further describes the different markers to identify stem cells, sources, methods of isolation, culture including 2D, 3D and beyond and their cryopreservation. This is among the first books to discuss glycosylation and sialylation in stem cells. Chapters describe application of stem cells in regenerative medicine and therapy, and highlight their application in cancer therapy and spinal cord injury. The book talks about the important patents on stem cells. The book also highlights the plant stem cells, discussing their pluoripotent nature, role in organ regeneration after injury, specific stem cell niches, that signals to block differentiation studied in plants shoot, root, and vascular meristems, differentiation of plant stem cell, transcriptional regulation and epigenetic modification of plant stem cells. This book is exciting and cutting edge. It will be of great interest to doctors, students and researchers in the field of regenerative medicine, cancer , biotechnology and plant sciences.

Tissue-specific stem cells have the capacity to self-renew and differentiate into several types of functional cells that replenish lost cells throughout an organism?s lifetime. Studies on stem cells from diverse systems have shown that stem cell function is controlled by extracellular cues from the niche and by intrinsic genetic programs within the stem cell. The objectives of this book would be to review the molecular mechanisms that mediate the balanced response of stem cells to the needs of the organisms. Likewise, niches have also been linked to pathologies, by imposing aberrant function on stem cells or other targets. Therefore, the second objective of this book would be to highligh the molecular dysregulation of niche biology leading to the disease. The third objective would be to review the therapeutical targets described within stem cell niches.

A discussion of all the key issues in the use of human pluripotent stem cells for treating degenerative diseases or for replacing tissues lost from trauma. On the practical side, the topics range from the problems of deriving human embryonic stem cells and driving their differentiation along specific lineages, regulating their development into mature cells, and bringing stem cell therapy to clinical trials. Regulatory issues are addressed in discussions of the ethical debate surrounding the derivation of human embryonic stem cells and the current policies governing their use in the United States and abroad, including the rules and conditions regulating federal funding and questions of intellectual property.

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.

This timely volume explores tissue-derived stem cells, summarizing and evaluating the current body of knowledge. Sixteen chapters cover hematopoietic, osteoblast, skeletal, cardiac, pancreatic, epithelial, corneal, hepatic, renal, testicular, ovarian, fingernail, hair follicle and other stem cells- discussing their individual development, functions and pathologies, as well as the commonalities and interdependence between niches. This installment of the popular Stem Cell Biology and Regenerative Medicine series delivers authoritative, international perspectives on this rapidly growing field. Tissue-Specific Stem Cell Niche is an ideal complementary volume to Biology of Stem Cell Niche and Adult Stem Cells, Second Edition and will be invaluable to clinicians and researchers working with stem cells as well as to postgraduate trainees who are studying them.
