(Submitter supplied) Here, we use microarrays to compare the transcriptome of mouse Pax7-GFP ES reporter cell line after 3 weeks of myogenic differentiation in vitro to that of undifferentiated ES Satellite cells (SC) are muscle stem cells which can regenerate adult muscles upon injury. Most SC originate from PAX7-positive myogenic precursors set aside during development. While myogenesis has been studied in mouse and chicken embryos, little is known about human muscle development. more...

(Submitter supplied) Satellite cells (SC) are muscle stem cells which can regenerate adult muscles upon injury. Most SC originate from PAX7+ myogenic precursors set aside during development. Although myogenesis has been studied in mouse and chicken embryos, little is known about human muscle development. Here, we report the generation of human induced pluripotent stem cell (iPSC) reporter lines in which fluorescent proteins have been introduced into the PAX7 and MYOG loci. more...

(Submitter supplied) Engineered CRISPR/Cas9-based transcriptional activators can potently and specifically activate endogenous fate-determining genes to direct differentiation of pluripotent stem cells. Here, we demonstrate that endogenous activation of the PAX7 transcription factor results in stable epigenetic remodeling and directly reprograms human pluripotent stem cells into skeletal myoblast progenitor cells. Compared to the exogenous overexpression of PAX7 cDNA, we find that endogenous activation results in the generation of more proliferative myogenic progenitors that can maintain PAX7 expression over multiple passages in serum-free conditions while preserving the capacity for terminal myogenic differentiation. more...

(Submitter supplied) We profiled gene expression of purified cell types isolated from 5 musculoskeletal tissues: tendon, bone, muscle, cartilage and ligament. We then performed WGCNA to identify tissue-specific transcription factors, signaling pathways and cell surface receptors. The sequencing data for muscle cells is made available here.

(Submitter supplied) The mechanisms by which Pax7 promotes skeletal muscle stem (satellite) cell identity are not yet understood. We have taken advantage of pluripotent stem cells wherein the induced expression of Pax7 robustly initiates the muscle program and enables the generation of muscle precursors that repopulate the satellite cell compartment upon transplantation. Pax7 binding was excluded from H3K27 tri-methylated regions, suggesting that recruitment of this factor is circumscribed by chromatin state. more...

(Submitter supplied) Skeletal muscle harbors quiescent stem cells termed satellite cells and proliferative progenitors termed myoblasts, which play pivotal roles during muscle regeneration. However, current technology does not allow permanent capture of these cell populations in vitro. Here, we show that ectopic expression of the myogenic transcription factor MyoD, combined with exposure to small molecules, reprograms mouse fibroblasts into expandable induced myogenic progenitor cells (iMPCs). more...

(Submitter supplied) The trithorax H3K4 histone methyltransferase (HMT) MLL1 has important roles for early embryonic development, hematopoiesis and neurogenesis through regulation of Hox and homeodomain factor expression. MLL1 has been previously implicated in activation of Myf5 expression through an interaction with Pax7. Here, we find that in vivo, MLL1 is necessary for efficient muscle regeneration, and for maintenance of muscle stem and progenitor cells. more...

(Submitter supplied) Skeletal myogenic commitment of human pluripotent cells can be achieved by doxycycline-inducible expression of the transcription factor PAX7. To gain further insights on PAX7 function during this process, we performed a time course whole transcriptome analysis of differentiating H9 human embryonic stem cells from doxycycline-treated and untreated cultures. In addition, we identified the genomic binding of PAX7 in one of the selected time point (referred as PAX7+ proliferating myogenic progenitors).

(Submitter supplied) Purpose: The aim of this study is to identify the Lsd1 genome binding profile in myoblast C2C12 cells during myogenic and adipogenic differentiation. ChIP-seq libraries were prepared, sequenced using the standard Illumina protocol (HiSeq2000, single read, 50 bp v3), and mapped to the mouse mm10 reference genome by Bowtie. Data were further analyzed using the peak finding algorithm MACS 1.4.2. Homer software was used to annotate peaks, and all peaks with false discovery rate less than 1 % were included.

(Submitter supplied) First, we aimed to identify genes whose transcript levels change at the onset of myogenic versus adipogenic differentiation of muscle precursors. We therefore compared RNA-seq results obtained from C2C12 cells differentiated for 1 day in myogenic and adipogenic medium. Out of these genes, we wanted to determine those whose expression was affected by altered Lsd1 levels. To this end, we performed RNA-seq in C2C12 cells upon LSD1 overexpression and Lsd1 knock-down in adipogenic medium and compared them to corresponding control cells.

(Submitter supplied) Myogenic differentiation of iPSCs has been done by gene–overexpression or directed differentiation. However, viral integration, long-term culture and the presence of unwanted cells are the main obstacles. By using CRISPR/Cas9n, a novel double reporter hESC line was generated for PAX7/MYF5, allowing prospective readout. This strategy allowed pathway screen to define efficient myogenic induction in hESC/iPSCs. more...

(Submitter supplied) It has been suggested that muscle stem cell function is regulated by Acetyl-CoA and NAD+ availability, but the mechanisms remain unclear. We identified two acetylation sites on PAX7 that positively regulate its transcriptional activity. Lack of PAX7 acetylation reduces DNA binding, specifically to the homeobox motif. The acetyltransferase MYST1 stimulated by Acetyl-CoA, and the deacetylase SIRT2 stimulated by NAD+, were identified as direct regulators of PAX7 acetylation and asymmetric division in muscle stem cells. more...

(Submitter supplied) Optimal cell-based therapies for the treatment of muscle degenerative disorders should not only regenerate fibers, but provide a quiescent satellite cell pool ensuring long-term maintenance and regeneration. Conditional expression of Pax3/Pax7 in differentiating pluripotent stem cells (PSC) allows the generation of myogenic progenitors endowed with satellite cell-like abilities. To identify the molecular determinants underlying their regenerative potential, we performed transcriptome analyses of these cells along with primary myogenic cells from several developmental stages. more...
