(Submitter supplied) Myogenic differentiation relies on Pax7 function. We used embryonic stem cells lacking functional Pax7 to follow its role in derivation of skeletal myoblasts. Microarray analysis allowed us to compare transcriptomes of undifferentiated and differentiating embryonic stem cells of two genotypes, i.e. Pax7+/+ and Pax7-/- at day 7 and 21 of culture.

(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...

(Submitter supplied) Using Hi-C, promoter-capture Hi-C (pCHi-C), and other genome-wide approaches in inducible Pax7-expressing skeletal muscle progenitors that inducibly express a master transcription factor, Pax7, we systematically characterized at high-resolution the spatio-temporal re-organization of compartments and promoter-anchored interactions as a consequence of myogenic commitment and differentiation. We identified key promoter-enhancer interaction motifs, namely, cliques and networks, and interactions that were dependent on Pax7 binding. 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) 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) 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 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) Skeletal muscle stem cells (MuSC), also called satellite cells, are indispensable for maintenance and regeneration of adult skeletal muscles. Yet, a comprehensive picture of the regulatory events controlling the fate of MuSC is missing. Here, we determine the proteome of MuSC to design a loss-of-function screen, and identify 120 genes important for MuSC function including the arginine methyltransferase Prmt5. 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...
