Abstract
Skeletal muscle stem cells (MuSCs) are recognised as functionally heterogeneous. Cranial MuSCs are reported to have greater proliferative and regenerative capacity when compared with those in the limb. A comprehensive understanding of the mechanisms underlying this functional heterogeneity is lacking. Here, we have used clonal analysis, live imaging and single cell transcriptomic analysis to identify crucial features that distinguish extraocular muscle (EOM) from limb muscle stem cell populations. A MyogeninntdTom reporter showed that the increased proliferation capacity of EOM MuSCs correlates with deferred differentiation and lower expression of the myogenic commitment gene Myod. Unexpectedly, EOM MuSCs activated in vitro expressed a large array of extracellular matrix components typical of mesenchymal non-muscle cells. Computational analysis underscored a distinct co-regulatory module, which is absent in limb MuSCs, as driver of these features. The EOM transcription factor network, with Foxc1 as key player, appears to be hardwired to EOM identity as it persists during growth, disease and in vitro after several passages. Our findings shed light on how high-performing MuSCs regulate myogenic commitment by remodelling their local environment and adopting properties not generally associated with myogenic cells.

Abstract
DNA integrity is incessantly confronted to agents inducing DNA lesions. All organisms are equipped with a network of DNA damage response mechanisms that will repair DNA lesions and restore proper cellular activities. Despite DNA repair mechanisms have been revealed in replicating cells, still little is known about how DNA lesions are repaired in postmitotic cells. Muscle fibers are highly specialized postmitotic cells organized in syncytia and they are vulnerable to age-related degeneration and atrophy after radiotherapy treatment. We have studied the DNA repair capacity of muscle fiber nuclei and compared it with the one measured in proliferative myoblasts here. We focused on the DNA repair mechanisms that correct ionizing radiation (IR)-induced lesions, namely the base excision repair, the nonhomologous end joining, and the homologous recombination (HR). We found that in the most differentiated myogenic cells, myotubes, these DNA repair mechanisms present weakened kinetics of recruitment of DNA repair proteins to IR-damaged DNA. For base excision repair and HR, this decline can be linked to reduced steady-state levels of key proteins involved in these processes.

Abstract
Skeletal muscle regeneration relies on muscle stem (satellite) cells. We previously demonstrated that satellite cells efficiently and accurately repair radiation-induced DNA double-strand breaks (DSBs) via the DNA-dependent kinase DNA-PKcs. We show here that DNA-PKcs affects myogenesis independently of its role in DSB repair. Consequently, this process does not require the accumulation of DSBs and it is also independent of caspase-induced DNA damage. We report that in myogenic cells DNA-PKcs is essential for the expression of the differentiation factor Myogenin in an Akt2-dependent manner. DNA-PKcs interacts with the p300-containing complex that activates Myogenin transcription. We show also that SCID mice that are deficient in DNA-PKcs, and are used for transplantation and muscle regeneration studies, display altered myofiber composition and delayed myogenesis upon injury. These defects are exacerbated after repeated injury/regeneration events resulting in reduced muscle size. We thus identify a novel, caspase-independent, regulation of myogenic differentiation, and define a differentiation phase that does not involve the DNA damage/repair process.

Expression patterns and correlation analyses of muscle-specific genes in the process of sheep myoblast differentiation. In Vitro Cell Dev Biol Anim 2022; 58:798-809.

Abstract
The purpose of this study was to establish a system for the isolation, culture, and differentiation of sheep myoblasts, and to explore the expression patterns as well as mutual relationships of muscle-specific genes. Sheep fetal myoblasts (SFMs) were isolated by two-step enzymatic digestion, purified by differential adhesion and identified using immunofluorescence techniques. Two percent horse serum was used to induce differentiation in SFMs. Real-time quantitative and Western blot analyses were respectively used to detect the mRNA and protein expressions of muscle-specific genes including MyoD, MyoG, Myf5, Myf6, PAX3, PAX7, myomaker, desmin, MYH1, MYH2, MYH4, MYH7, and MSTN during the differentiation of SFMs. Finally, the correlation between muscle-specific genes was analyzed by the Pearson correlation coefficient method. The results showed that the isolated and purified SFMs could form myotubes after the induction for differentiation. The marker factors including MyoD, MyoG, myomaker, desmin, and MyHC were positively stained in SFMs. The mRNA expressions of MyoD, MyoG, and myomaker increased and then decreased, while Myf5, PAX3, and PAX7 decreased; Myf6, desmin, MYH1, MYH2, MYH4, and MYH7 increased; and MSTN fluctuated up and down during the differentiation of SFMs. The expression patterns of protein were basically consistent with those of mRNA except MSTN. There existed significant or highly significant correlations at mRNA or protein level among some genes. Some transcription factor proteins (MyoD, Myf5, Myf6, PAX3, PAX7) showed significant or highly significant correlations with the mRNA level of some other genes and/or themselves. In conclusion, SFMs with good myogenic differentiation ability were successfully isolated, and the expression patterns and correlations of muscle-specific genes during SFM differentiation were revealed, which laid an important foundation for elucidating the gene regulation mechanism of sheep myogenesis.

Abstract
Background Myogenin is a transcription factor that is expressed during terminal myoblast differentiation in embryonic development and adult muscle regeneration. Investigation of this cell state transition has been hampered by the lack of a sensitive reporter to dynamically track cells during differentiation. Results Here, we report a knock-in mouse line expressing the tdTOMATO fluorescent protein from the endogenous Myogenin locus. Expression of tdTOMATO in MyogntdTom mice recapitulated endogenous Myogenin expression during embryonic muscle formation and adult regeneration and enabled the isolation of the MYOGENIN+ cell population. We also show that tdTOMATO fluorescence allows tracking of differentiating myoblasts in vitro and by intravital imaging in vivo. Lastly, we monitored by live imaging the cell division dynamics of differentiating myoblasts in vitro and showed that a fraction of the MYOGENIN+ population can undergo one round of cell division, albeit at a much lower frequency than MYOGENIN− myoblasts. Conclusions We expect that this reporter mouse will be a valuable resource for researchers investigating skeletal muscle biology in developmental and adult contexts.

Abstract
The maintenance of adult stem cells in their normal quiescent state depends on intrinsic factors and extrinsic signals originating from their microenvironment (also known as the stem cell niche). In skeletal muscle, its stem cells (satellite cells) lose their regenerative potential with aging, and this has been attributed, at least in part, to both age-associated changes in the satellite cells as in the niche cells, which include resident fibro-adipogenic progenitors (FAPs), macrophages, and endothelial cells, among others. To understand the regenerative decline of skeletal muscle with aging, there is a need for methods to specifically isolate stem and niche cells from resting muscle. Here we describe a fluorescence-activated cell sorting (FACS) protocol to simultaneously isolate discrete populations of satellite cells and niche cells from skeletal muscle of aging mice.

Abstract
BACKGROUND The dramatic increase in myotomal muscle mass in post-hatching fish is related to their ability to lastingly produce new muscle fibres, a process termed hyperplasia. The molecular and cellular mechanisms underlying fish muscle hyperplasia largely remain unknown. In this study, we aimed to characterize intrinsic properties of myogenic cells originating from hyperplasic fish muscle. For this purpose, we compared in situ proliferation, in vitro cell behavior and transcriptomic profile of myogenic precursors originating from hyperplasic muscle of juvenile trout (JT) and from non-hyperplasic muscle of fasted juvenile trout (FJT) and adult trout (AT). RESULTS For the first time, we showed that myogenic precursors proliferate in hyperplasic muscle from JT as shown by in vivo BrdU labeling. This proliferative rate was very low in AT and FJT muscle. Transcriptiomic analysis revealed that myogenic cells from FJT and AT displayed close expression profiles with only 64 differentially expressed genes (BH corrected p-val < 0.001). In contrast, 2623 differentially expressed genes were found between myogenic cells from JT and from both FJT and AT. Functional categories related to translation, mitochondrial activity, cell cycle, and myogenic differentiation were inferred from genes up regulated in JT compared to AT and FJT myogenic cells. Conversely, Notch signaling pathway, that signs cell quiescence, was inferred from genes down regulated in JT compared to FJT and AT. In line with our transcriptomic data, in vitro JT myogenic precursors displayed higher proliferation and differentiation capacities than FJT and AT myogenic precursors. CONCLUSIONS The transcriptomic analysis and examination of cell behavior converge to support the view that myogenic cells extracted from hyperplastic muscle of juvenile trout are intrinsically more potent to form myofibres than myogenic cells extracted from non-hyperplasic muscle. The generation of gene expression profiles in myogenic cell extracted from muscle of juvenile trout may yield insights into the molecular and cellular mechanisms controlling hyperplasia and provides a useful list of potential molecular markers of hyperplasia.

Abstract
Cell fate decisions occur through the action of multiple factors, including signalling molecules and transcription factors. Recently, the regulation of translation has emerged as an important step for modulating cellular function and fate, as exemplified by ribosomes that play distinct roles in regulating cell behaviour. Notchless (Nle) is a conserved nuclear protein that is involved in a crucial step in ribosome biogenesis, and is required for the maintenance of adult haematopoietic and intestinal stem/progenitor cells. Here, we show that activated skeletal muscle satellite cells in conditional Nle mutant mice are arrested in proliferation; however, deletion of Nle in myofibres does not impair myogenesis. Furthermore, conditional deletion of Nle in satellite cells during homeostasis did not impact on their fate for up to 3 months. In contrast, loss of Nle function in primary myogenic cells blocked proliferation because of major defects in ribosome formation. Taken together, we show that muscle stem cells undergo a stage-specific regulation of ribosome biogenesis, thereby underscoring the importance of differential modulation of mRNA translation for controlling cell fate decisions.

Abstract
Muscle stem cells (MuSCs) are essential for maintaining muscle homeostasis by providing progenitor cells for muscle regeneration after injury and in muscular diseases. MuSC properties dynamically change, reflecting physiology or pathological status. For instance, MuSCs are activated after muscle injury, but become exhausted in late stages of Duchenne Muscular Dystrophy (DMD) disease and senescent during aging. Therefore, characterization of MuSCs, including proliferation, activation, senescence, and apoptosis, etc., is very important in applying MuSC knowledge to regenerative medicine, such as in the treatment of DMD and to improve muscle function in aging. Here, we describe a detailed method for characterizing MuSCs in situ using immunostaining techniques in the mouse. This method can also be easily adapted to analyze other skeletal muscle properties. © 2018 by John Wiley & Sons, Inc.

Here, we characterise the metabolic pathways that mediate the commitment and differentiation of mouse skeletal muscle stem cells, and how their modulation can influence the cell state. We show that quiescent satellite stem cells have low energetic demands and perturbed oxidative phosphorylation during ageing, which is also the case for cells from post-mortem tissues. We show also that myogenic fetal cells have distinct metabolic requirements compared to those proliferating during regeneration, with the former displaying a low respiration demand relying mostly on glycolysis. Furthermore, we show distinct requirements for peroxisomal and mitochondrial fatty acid oxidation (FAO) in myogenic cells. Compromising peroxisomal but not mitochondrial FAO promotes early differentiation of myogenic cells. Acute muscle injury and pharmacological block of peroxisomal and mitochondrial FAO expose differential requirements for these organelles during muscle regeneration. Taken together, these observations indicate that changes in myogenic cell state lead to significant alterations in metabolic requirements. In addition, perturbing specific metabolic pathways impacts on myogenic cell fates and the regeneration process. Summary: Distinct energy metabolism pathways act during mouse skeletal muscle stem cell commitment and differentiation in different physiological states.

Abstract
Skeletal muscle satellite cells are quiescent adult resident stem cells that activate, proliferate and differentiate to generate myofibres following injury. They harbour a robust proliferation potential and self-renewing capacity enabling lifelong muscle regeneration. Although several classes of microRNAs were shown to regulate adult myogenesis, systematic examination of stage-specific microRNAs during lineage progression from the quiescent state is lacking. Here we provide a genome-wide assessment of the expression of small RNAs during the quiescence/activation transition and differentiation by RNA-sequencing. We show that the majority of small RNAs present in quiescent, activated and differentiated muscle cells belong to the microRNA class. Furthermore, by comparing expression in distinct cell states, we report a massive and dynamic regulation of microRNAs, both in numbers and amplitude, highlighting their pivotal role in regulation of quiescence, activation and differentiation. We also identify a number of microRNAs with reliable and specific expression in quiescence including several maternally-expressed miRNAs generated at the imprinted Dlk1-Dio3 locus. Unexpectedly, the majority of class-switching miRNAs are associated with the quiescence/activation transition suggesting a poised program that is actively repressed. These data constitute a key resource for functional analyses of miRNAs in skeletal myogenesis, and more broadly, in the regulation of stem cell self-renewal and tissue homeostasis.

Abstract
BACKGROUND Skeletal muscle satellite (stem) cells are quiescent in adult mice and can undergo multiple rounds of proliferation and self-renewal following muscle injury. Several labs have profiled transcripts of myogenic cells during the developmental and adult myogenesis with the aim of identifying quiescent markers. Here, we focused on the quiescent cell state and generated new transcriptome profiles that include subfractionations of adult satellite cell populations, and an artificially induced prenatal quiescent state, to identify core signatures for quiescent and proliferating. METHODS Comparison of available data offered challenges related to the inherent diversity of datasets and biological conditions. We developed a standardized workflow to homogenize the normalization, filtering, and quality control steps for the analysis of gene expression profiles allowing the identification up- and down-regulated genes and the subsequent gene set enrichment analysis. To share the analytical pipeline of this work, we developed Sherpa, an interactive Shiny server that allows multi-scale comparisons for extraction of desired gene sets from the analyzed datasets. This tool is adaptable to cell populations in other contexts and tissues. RESULTS A multi-scale analysis comprising eight datasets of quiescent satellite cells had 207 and 542 genes commonly up- and down-regulated, respectively. Shared up-regulated gene sets include an over-representation of the TNFα pathway via NFKβ signaling, Il6-Jak-Stat3 signaling, and the apical surface processes, while shared down-regulated gene sets exhibited an over-representation of Myc and E2F targets and genes associated to the G2M checkpoint and oxidative phosphorylation. However, virtually all datasets contained genes that are associated with activation or cell cycle entry, such as the immediate early stress response genes Fos and Jun. An empirical examination of fixed and isolated satellite cells showed that these and other genes were absent in vivo, but activated during procedural isolation of cells. CONCLUSIONS Through the systematic comparison and individual analysis of diverse transcriptomic profiles, we identified genes that were consistently differentially expressed among the different datasets and shared underlying biological processes key to the quiescent cell state. Our findings provide impetus to define and distinguish transcripts associated with true in vivo quiescence from those that are first responding genes due to disruption of the stem cell niche.

Abstract
Skeletal muscle stem cells, originally termed satellite cells for their position adjacent to differentiated muscle fibers, are absolutely required for the process of skeletal muscle repair and regeneration. In the last decade, satellite cells have become one of the most studied adult stem cell systems and have emerged as a standard model not only in the field of stem cell-driven tissue regeneration but also in stem cell dysfunction and aging. Here, we provide background in the field and discuss recent advances in our understanding of muscle stem cell function and dysfunction, particularly in the case of aging, and the potential involvement of muscle stem cells in genetic diseases such as the muscular dystrophies.
