Book Synopsis Stem Cells and Cell Signalling in Skeletal Myogenesis by : D.A. Sassoon
Download or read book Stem Cells and Cell Signalling in Skeletal Myogenesis written by D.A. Sassoon and published by Elsevier. This book was released on 2002-02-08 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Skeletal muscle development is perhaps one of the best understood processes at the molecular, cellular and organismal level due in large part to the fact that primary myogenic cells (myoblasts) will grow and subsequently differentiate into myotubes in culture. With the advent of reverse mouse genetics, many of the observations gained through the study of myogenic cells in vitro have been directly tested in vivo. What has emerged is a complex but cohesive story of how myogenic cells are initially specified in the vertebrate embryo and how muscle fibers ultimately achieve their respective identities (i.e. fast versus slow) to perform their function. This collection of chapters is focused on these developments. The book discusses old and new directions for the skeletal muscle field and points out directions where the field may eventually progress.

Book Synopsis Role of Stem Cells in Skeletal Muscle Development, Regeneration, Repair, Aging and Disease by : Pura Muñoz-Cánoves
Download or read book Role of Stem Cells in Skeletal Muscle Development, Regeneration, Repair, Aging and Disease written by Pura Muñoz-Cánoves and published by Frontiers Media SA. This book was released on 2016-06-29 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adult stem cells are responsible for tissue regeneration and repair throughout life. Their quiescence or activation are tightly regulated by common signalling pathways that often recapitulate those happening during embryonic development, and thus it is important to understand their regulation not only in postnatal life, but also during foetal development. In this regard, skeletal muscle is an interesting tissue since it accounts for a large percentage of body mass (about 40%), it is highly amenable to intervention through exercise and it is also key in metabolic and physiological changes underlying frailty susceptibility in the elderly. While muscle-resident satellite cells are responsible for all myogenic activity in physiological conditions and become senescent in old age, other progenitor cells such as mesoangioblasts do seem to contribute to muscle regeneration and repair after tissue damage. Similarly, fibro-adipogenic precursor cells seem to be key in the aberrant response that fills up the space left from atrophied muscle mass and which ends up with a dysfunctional muscle having vast areas of fatty infiltration and fibrosis. The complex interplay between these stem/progenitor cell types and their niches in normal and pathological conditions throughout life are the subjects of intense investigation. This eBook highlights recent developments on the role of stem cells in skeletal muscle function, both in prenatal and postnatal life, and their regulation by transcriptional, post-transcriptional and epigenetic mechanisms. Additionally, it includes articles on interventions associated with exercise, pathological changes in neuromuscular diseases, and stem cell aging.
Book Synopsis Vertebrate Myogenesis by : Beate Brand-Saberi
Download or read book Vertebrate Myogenesis written by Beate Brand-Saberi and published by Springer. This book was released on 2014-10-25 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the differentiation control of skeletal muscle in different locations of the vertebrate body Particular attention is paid to novel regulatory molecules and signals as well as the heterogeneity of origin that have revealed a developmental overlap between skeletal and cardiac muscle. Different functional muscle groups are the product of the evolution of the vertebrate classes, making a phylogenetic comparison worthwhile for understanding the role of muscle stem cells and precursors in myogenesis. New insights into the hierarchy of transcription factors, particularly in the context of these different muscle groups have been gained from detailed investigations of the spatio-temporal and regulatory relationships derived from mouse and zebrafish genetics and avian microsurgery. Importantly, epigenetic mechanisms that have surfaced recently, in particular the role of MyomiRs, are also surveyed. With an eye to the human patient, encouraging results have been generated that identify parallels between embryonic myogenesis and regenerating myofibers due to common regulatory molecules. On the other hand, both processes differ considerably in quality and complexity of the processes employed. Interestingly, the heterogeneity in embryonic sources from which skeletal muscle groups in the vertebrate including the human body take origin is paralleled by differences in their susceptibility to particular muscle dystrophies as well as by the characteristics of the satellite cells involved in regeneration. The progress that has been made in the field of muscle stem cell biology, with special focus on the satellite cells, is outlined in this book by experts in the field. The authors review recent insights of the heterogeneous nature of these satellite cells regarding their gene signatures and regeneration potential. Furthermore, an improved understanding of muscle stem cells seems only possible when we study the impact of the cell environment on efficient stem cell replacement therapies for muscular dystrophies, putting embryological findings from different vertebrate classes and stem cell approaches into context.

Book Synopsis Stem Cells: A Cellular Fountain of Youth by : M.P. Mattson
Download or read book Stem Cells: A Cellular Fountain of Youth written by M.P. Mattson and published by Elsevier. This book was released on 2002-08-21 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Frontiers in Skeletal Muscle Wasting, Regeneration and Stem Cells by : Carlos Hermano J. Pinheiro

This book was released on 2016-05-25 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: The search for knowledge on cellular and molecular mechanisms involved in skeletal muscle mass homeostasis and regeneration is an exciting scientific area and extremely important to develop therapeutic strategies for neuromuscular disorders and conditions related to muscle wasting. The mechanisms involved in the regulation of skeletal muscle mass and regeneration consist of molecular signaling pathways modulating protein synthesis and degradation, bioenergetics alterations and preserved function of muscle stem cells. In the last years, different kinds of stem cells has been reported to be localized into skeletal muscle (satellite cells, mesoangioblasts, progenitor interstitial cells and others) or migrate from non-muscle sites, such as bone marrow, to muscle tissue in response to injury. In addition, myogenic progenitor cells are also activated in skeletal muscle wasting disorders. The goal of this research topic is to highlight the available knowledge regarding skeletal muscle and stem cell biology in the context of both physiological and pathological conditions. Our purpose herein is to facilitate better dissemination of research into skeletal muscle physiology field.

Book Synopsis The Transcriptional Regulation of Stem Cell Differentiation Programs by Hedgehog Signalling by : Anastassia Voronova
Download or read book The Transcriptional Regulation of Stem Cell Differentiation Programs by Hedgehog Signalling written by Anastassia Voronova and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hedgehog (Hh) signalling pathway is one of the key signalling pathways orchestrating intricate organogenesis, including the development of neural tube, heart and skeletal muscle. Yet, insufficient mechanistic understanding of its diverse roles is available. Here, we show the molecular mechanisms regulating the neurogenic, cardiogenic and myogenic properties of Hh signalling, via effector protein Gli2, in embryonic and adult stem cells. In Chapter 2, we show that Gli2 induces neurogenesis, whereas a dominant-negative form of Gli2 delays neurogenesis in P19 embryonal carcinoma (EC) cells, a mouse embryonic stem (ES) cell model. Furthermore, we demonstrate that Gli2 associates with Ascl1/Mash1 gene elements in differentiating P19 cells and activates the Ascl1/Mash1 promoter in vitro. Thus, Gli2 mediates neurogenesis in P19 cells at least in part by directly regulating Ascl1/Mash1 expression. In Chapter 3, we demonstrate that Gli2 and MEF2C bind each other's regulatory elements and regulate each other's expression while enhancing cardiomyogenesis in P19 cells. Furthermore, dominant-negative Gli2 and MEF2C proteins downregulate each other's expression while imparing cardiomyogenesis. Lastly, we show that Gli2 and MEF2C form a protein complex, which synergistically activates cardiac muscle related promoters. In Chapter 4, we illustrate that Gli2 associates with MyoD gene elements while enhancing skeletal myogenesis in P19 cells and activates the MyoD promoter in vitro. Furthermore, inhibition of Hh signalling in muscle satellite cells and in proliferating myoblasts leads to reduction in MyoD and MEF2C expression. Finally, we demonstrate that endogenous Hh signalling is important for MyoD transcriptional activity and that Gli2, MEF2C and MyoD form a protein complex capable of inducing skeletal muscle-specific gene expression. Thus, Gli2, MEF2C and MyoD participate in a regulatory loop and form a protein complex capable of inducing skeletal muscle-specific gene expression. Our results provide a link between the regulation of tissue-restricted factors like Mash1, MEF2C and MyoD, and a general signal-regulated Gli2 transcription factor. We therefore provide novel mechanistic insights into the neurogenic, cardiogenic and myogenic properties of Gli2 in vitro, and offer novel plausible explanations for its in vivo functions. These results may also be important for the development of stem cell therapy strategies.

Book Synopsis Generation and Characterization of Human Embryonic Stem Cells-Derived Skeletal Muscle Progenitors by : Michael L. Shelton
Download or read book Generation and Characterization of Human Embryonic Stem Cells-Derived Skeletal Muscle Progenitors written by Michael L. Shelton and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The long-term treatment of injured, aging, or pathological skeletal muscle using stem cell therapy requires an abundant source of skeletal muscle progenitors (SMP) that are capable of self-replenishment. While adult SMPs-known as satellite cells and marked by PAX7 expression-can be collected from healthy donors, these satellite cells have limited replication potential once extracted, and may have difficulties providing sufficient numbers for therapy. Therefore, we sought to utilize the near-unlimited replication potential of human embryonic stem cells (hESC) to generate large quantities of SMPs in vitro. We developed a 50-day directed hESC differentiation that produced cultures with up to 90% myogenic identity; roughly 43 ± 4% become PAX7+ SMPs, and 47 ± 3% of cells become skeletal myocytes. We also performed gene expression profiling on our differentiating cultures to better understand in vitro skeletal myogenesis, and to better characterize in vitro hESC-derived SMPs, which remain poorly understood relative to adult satellite cells. 50-day cultures shared gene expression profiles more similar to quiescent rather than activated satellite cells, featuring a number of genes related to FOS/JUN, NOTCH, and TGFB-signaling. Day 50 cultures also expressed surface proteins known to mark adult or embryonic SMPs: CD82, CXCR4, ERBB3, NGFR, and PDGFRA. Transplanting 50-day cultures into cardiotoxin or BaCl2 injured immunodeficient murine muscle showed donor human cells persisted within the host muscle for 1 - 2 months post-injection; however, donor cells were confined to the interstitial space and did not contribute to host myofibers or the satellite cell niche. Together, these studies provide a tool for generating large quantities of embryonic skeletal muscle, and a gene expression resource that can provide insight into signaling factors that might improve or accelerate SMP development, or provide putative new surface receptors that may isolate embryonic SMPs better suited for in vivo transplantation.

Book Synopsis Signalling Pathways in Embryonic Development by : Juan J. Sanz-Ezquerro
Download or read book Signalling Pathways in Embryonic Development written by Juan J. Sanz-Ezquerro and published by Frontiers Media SA. This book was released on 2017-11-30 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: The formation of a complex multicellular organism from a single cell is one of the most amazing processes of biology. Embryonic development is characterised by the careful regulation of cellular behaviours such that cells proliferate, migrate, differentiate and form tissues at the correct place and time. These processes are genetically controlled and depend both on the history of cells, their lineage, and on the activities of signalling pathways, which coordinate the cell interactions leading to organogenesis. The aim of the Frontiers research topic “Signalling pathways in embryonic development” has been to provide a forum for experts in cell and developmental biology to share recent advances in the field of signalling during embryonic development. Sixteen articles in a variety of formats are united in this Topic, offering a valuable collection for researchers looking for an update in the knowledge of signalling pathways operating during embryogenesis. The works, focused mainly on vertebrates, explore different aspects of this theme from cell communication to organ formation and have implications for areas as distant as evolution or pathology. Understanding developmental signalling pathways is important for several reasons. It gives us information about basic mechanisms of cell function and interactions needed for morphogenesis and organogenesis. It uncovers the basis of congenital malformations, since errors at any step of cell signalling during development are a major cause of defects. This fundamental insight gives us clues to understand the mechanisms operating in evolution that explain diversity in form and function. And finally, it allows the identification of possible causes of disease in the adult organism (such as cancer or degenerative diseases) pinpointing possible targets for therapeutic approaches.

Download or read book Retinoic Acid Receptor Signaling in the Differentiation of Pluripotent Stem Cells Into Skeletal Muscle Lineage written by Jihong Chen and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Pluripotent stem cells have the capacity to differentiate into many types of cell lineages including skeletal myocytes. Nevertheless, the frequency of pluripotent stem cells generating skeletal myocytes in the absence of developmental cues is very low, and signaling molecules are required to commit them to muscle lineage. Thereby, in vitro stem cell differentiation has been used for decades to study molecular mechanisms of myogenic specification. Similar to human embryonic stem (ES) cells, various mouse pluripotent stem cells respond well to development cues in vitro to differentiate into cell types of all three primary germ layers. In tissue cultures, they can be induced into myogenic differentiation with an aggregation protocol which involves the formation of embryoid bodies (EBs). Their commitment into the skeletal muscle lineage recapitulates closely the cellular and molecular processes occurring in the early embryogenesis. Treatment of these stem cells with regulatory signals important for embryonic development, such as ligands of nuclear receptors, during EB formation markedly enhances the efficiency of myogenic differentiation. However, many challenges remain. Understanding on a molecular level, how different signaling pathways and chromatin dynamics converge during stem cell differentiation to specify the muscle lineage is imperative for identifying effective signaling molecules to generate sufficient amount of muscle progenitor cells for potential therapeutics. To this end, mouse stem cells will continue to serve as valuable model systems due to their close resemblance to skeletal myogenesis in vivo, and the ease of manipulation in experimental procedures. In this chapter, we will focus on recent research findings on nuclear receptor signaling in the specification of skeletal muscle lineage.
