(Submitter supplied) Human pluripotent stem cell- (hPSC)-derived skeletal muscle progenitors (SMP)—defined as PAX7-expressing cells with myogenic potential—can provide an abundant source of donor material for muscle stem cell therapy owing to the near-infinite replication potential of PSCs. As in vitro myogenesis is decoupled from in vivo timing and the 3D-embryo structure, it remains difficult to definitively characterize what stage or type of muscle is modeled in culture. more...

(Submitter supplied) The transcriptional mechanisms driving lineage specification during development are still largely unknown as the interplay of multiple transcription factors makes it difficult to dissect these molecular events. Using a cell-based differentiation platform to probe transcription function, we investigated the role of the key paraxial mesoderm and skeletal myogenic commitment factors, Msgn1, Tbx6, Foxc1, Pax3, Paraxis, Meox1, Six1 and Myf5, in paraxial mesoderm and skeletal myogenesis. more...

(Submitter supplied) (Abstract of publication submitted currently) To clarify molecular regulation of satellite cells, we performed genome-wide gene expression analysis of quiescent satellite cells isolated from mouse skeletal muscle by flow cytometry. We identified 53 novel quiescent satellite cell-specific genes whose expressions are sharply down-regulated upon activation. The gene list contains a number of cell surface molecules, transcriptional factors, and cytokines and other signal transduction molecules. more...

(Submitter supplied) Stem cell-derived tissues have wide potential for modelling developmental and pathological processes as well as cell-based therapy. However, it has proven difficult to generate several key cell types in vitro, including skeletal muscle. In vertebrates, skeletal muscles derive during embryogenesis from the presomitic mesoderm (PSM). Using PSM development as a guide, we establish conditions for the differentiation of monolayer cultures of human pluripotent stem (hPSC) cells into PSM-like cells without the introduction of transgenes or cell sorting. more...

(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) 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) Cellular differentiation involves widespread epigenetic reprogramming, including modulation of DNA methylation patterns. We have investigated DNA genome-wide methylation dynamics in embryonic stem cells, primary myoblasts, terminal differentiated myotubes and mature myofibers. About 1.000 differentially methylated regions (DMRs) have been indentified during muscle-lineage determination and terminal differentiation. more...

(Submitter supplied) Human pluripotent stem cell derived muscle models show great potential for translational research. Here, we describe novel developmentally inspired methods for the derivation of skeletal muscle cells and their utility in three-dimensional skeletal muscle organoid formation as well as skeletal muscle tissue engineering. Three-dimensional organoid and tissue engineered models exhibit organotypic maturation and function and regenerative responses, recapitulating canonical properties of bona fide skeletal muscle in vivo. more...

(Submitter supplied) Directing differentiation of human embryonic stem cells (hESC) into specific cell types using an easy and reproducible protocol is a perquisite for the clinical use of hESC in regenerative medicine protocols. Here, we report the generation of mesodermal cells with differentiation potential to myocytes, osteoblasts, chondrocytes and adipocytes. We demonstrate that during hESC differentiation as embryoid bodies (EB), inhibition of TGF-b/Activin/Nodal signaling using SB-431542 (SB) markedly up-regulated paraxial mesodermal markers (TBX6, TBX5), early myogenic transcriptional factors (Myf5, Pax7) as well as myocyte committed markers (NCAM, CD34, Desmin, MHC (fast), alpha-smooth muscle actin, Nkx2.5, cTNT). more...

(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) The acquisition of a proliferating cell status from a quiescent state as well as the shift between proliferation and differentiation are key developmental steps in skeletal-muscle stem cells (satellite cells) to provide proper muscle regeneration. However, how satellite-cell proliferation is regulated, though, is not fully understood. Here, we report that the c-isoform of the transcription factor Pitx2 increases cell proliferation in myoblasts by down-regulating the miRNAs miR-15b, miR-23b, miR-106b, and miR-503. more...

(Submitter supplied) We outline an in vivo cellular program of bovine longissimus muscle development inferred from expression data from 60 days post conception to 3 months postnatal. Analytic challenges included changes in cellular composition, ambiguous ‘diagnostic’ markers of cell type and contrasts between cattle human and mouse myogenesis. Nevertheless, the expression profiles of the myosin isoforms support slow and fast muscle fibres emanating from primary and secondary myogenesis respectively, while expression of the prenatal myosin subunits is down regulated prior to birth. more...
