Available in PDF, EPUB and Kindle. Book excerpt: Stem cells are defined as undifferentiated cells that are able to unlimitedly renew themselves within controlled conditions and to differentiate into a multitude of mature cell types. Skeletal muscle stem cells, represented predominantly by satellite cells, show a variable capability of self-renewal and myogenic differentiation. They were found to be involved not only in the growth of myofibers during neonatal and juvenile life but also in the regeneration of skeletal muscles after an injury. The microenvironment in which stem cells are nourished and maintained dormant preceding division and differentiation is known as ,Äúniche.,Äù The niche consists of myofibers, which are believed to modulate the active/inactive state of the stem cells, extracellular matrix, neural networks, blood vessels, and a multitude of soluble molecules. It was observed that changes in the composition of the niche have an impact on the stem cell functions and hierarchy. Furthermore, it seems that its layout is variable throughout the entire life, translating into a decrease in the regenerative capacity of satellite cells in aged tissues. The scope of this chapter is to provide a detailed view of the changes that occur in the skeletal stem cell niche during life and to analyze their implications on tissue regeneration. Future studies should focus on developing new therapeutic tools for diseases involving muscle atrophy.

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 excerpt: Satellite cells are considered the major source of muscle progenitors, however, other populations with myogenic popential have been discovered. We have identified a new muscle-resident non-satellite cell population, termed PICs, which can differentiate into three different lineages, skeletal muscle, smooth muscle and fat. PICs rescue satellite cells from myostatin inhibition in vitro through follistatin release. When myostatin is inactivated in vivo, PICs number is markedly increased and mice display hypertrophied muscles. While recent studies have demonstrated that muscle regeneration cannot occur without satellite cells, we show that muscle regeneration is restored when mice have been previously treated with a myostatin inhibitor. We postulate that PICs have participated in muscle repair rescue, and thus constitute an interesting population to be targeted for pharmaceutical strategies aimed at improving skeletal muscle mass and function.

Download or read book Role of Stem Cells and Extracellular Matrix in the Regeneration of Skeletal Muscle written by Andrew Dunn and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Adult skeletal muscle has a remarkable capacity to initiate a rapid and extensive repair process after damage due to injury or degenerative disease. Although satellite cells are the primary skeletal muscle stem cells, there are many reports of non-satellite cell populations with myogenic capacity resident within skeletal muscle. The activity of muscle-resident stem cells during the regeneration process is tightly controlled through the dynamic interactions between intrinsic factors within the cells and extrinsic factors constituting the muscle stem cell niche. The extracellular matrix (ECM) in skeletal muscle plays an integral role in force transmission, structural maintenance, and regulation of stem cell niche. ECM interacts with stem cells either directly by binding cell surface receptors or indirectly through growth factor presentation, and maintains a balance between their quiescence, self-renewal, and differentiation. These interactions are reciprocal since the stem cells can remodel the niche and secrete or degrade ECM components. Natural ECM scaffolds, derived from decellularized tissues can influence stem cell activity both in vitro and in vivo and are widely being investigated for skeletal muscle repair. In this chapter, we discuss the regenerative potential of stem cell populations and ECM bioscaffolds in the treatment of skeletal muscle injury and disease.

Download or read book A Multi angled Approach to Discover and Improve Skeletal Muscle Stem Cell Therapies written by Sadegh Davoudi and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Skeletal muscle plays an essential role in locomotion, metabolism, and thermoregulation. An intriguing characteristic of skeletal muscle is its remarkable regenerative capacity: a highly orchestrated cellular process, in which the resident muscle stem cells (MuSCs) play a central role. Upon tissue injury, quiescent MuSCs are activated and give rise to a population of primary myoblasts (pMBs). pMBs undergo several rounds of division and ultimately fuse with one another to form multi-nucleated myofibers and repair the muscle. As observed in a wide range of conditions such as muscular dystrophies and aging, disruptions in the repair process can lend to impaired regeneration and progressive muscle wasting. Strategies to restore strength and function to pathological muscle include cell-based therapies to replace defective myogenic cells, and treatments to restore the endogenous repair process. Despite substantial advances, these treatment options are still in the early stages of clinical translation. The specific goal of this thesis is to improve upon currently available strategies as well as to lay the groundwork for the emergence of new therapeutic entry-points for skeletal muscle treatments. In the area of cell transplantation therapy, challenges remain in producing clinically-relevant numbers of cells that, as a population, possess high regenerative potency to produce skeletal muscle and repopulate the stem cell niche. We demonstrate that by using a bioactive hydrogel (HAMC) as the cell delivery vehicle, it is possible to improve MuSC transplantation outcomes, and thereby reduce the overall number of required MuSCs. Next, we address the issue of producing sufficient numbers of highly regenerative myogenic cells. Using a high-throughput drug screen and in-vivo intramuscular transplantation assay validation, we identify epidermal growth factor receptor (Egfr) and vascular endothelial growth factor receptor 2 (Vegfr2, Kdr) as new druggable targets, that upon inhibition, produce a population of cultured MuSCs with greater regenerative potency than control treated. Finally, using single-cell RNA sequencing, we shed light on the diversity and intercommunication of cells present in skeletal muscle. This dataset serves as a valuable resource through which new regulators of MuSCs and other cells in skeletal muscle can be evaluated with an eye towards skeletal muscle regenerative medicine applications.
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.
