(Submitter supplied) Muscle is known to be a highly glycolytic tissue, yet the impact of glucose metabolism in muscle stem cell function remains unresolved. Here we use Mass Cytometry (CyTOF) to capture changes in histone acetylation profiles at the single cell level in vivo following injury. We demonstrate that MuSCs transiently increase histone acetylation upon activation, followed by global loss upon commitment. The switch to a committed state is driven by glucose metabolism through pyruvate dehydrogenase (PDH), which fuels histone acetylation via production of acetyl-CoA. more...

(Submitter supplied) Stem cells reside in specialized niches that play a critical role in modulating their fate. Supporting cells in the niche instruct fate changes to the stem cells through epigenetic enzymes that transduce cell signaling to modify gene expression. Recent studies showed that the innate immune response to muscle injury alters the muscle stem cell (MuSC) niche, it remains unknown how MuSC adapt to the modified milieu to mediate muscle repair. more...

(Submitter supplied) Skeletal muscle possesses remarkable regenerative ability owing to the resident muscle stem cells (MuSCs). A prominent feature of quiescent MuSCs is a high content of heterochromatin. However, little is known about the mechanisms by which heterochromatin is maintained in MuSCs. We found that the mammalian Hairless (Hr) gene is expressed in quiescent MuSCs. Using a mouse model in which Hr can be specifically ablated in MuSCs, we demonstrate that Hr expression is critical for MuSC function and muscle regeneration. more...

(Submitter supplied) Abstract: Transcription factors (TFs) play key roles in regulating differentiation and function of stem cells, including muscle satellite cells (MuSCs), a resident stem cell population responsible for postnatal regeneration of the skeletal muscle. Sox11 belongs to the Sry-related HMG-box (SOX) family of TFs that play diverse roles in stem cell behavior and tissue specification. Analysis of single-cell RNA-sequencing (scRNA-seq) datasets identify a specific enrichment of Sox11 mRNA in differentiating but not quiescent MuSCs. more...

(Submitter supplied) Successful skeletal muscle regeneration is primarily mediated by muscle stem cells or satellite cells which express Pax7. In homeostasis, these satellite cells exist in a ‘genuine quiescent’ state, although some satellite cells may also be primed. After an acute injury, satellite cells, enabled by several other niche cells in the muscle tissue, undergo a series of molecular and cellular changes such as activation, proliferation, and differentiation. more...

(Submitter supplied) Muscle satellite cells (MuSCs), skeletal muscle-resident stem cells, are crucial for regeneration of myofibers. Mechanical cues are thought to be important for activation and proliferation of muscle satellite cells, but the molecular entity that senses biophysical forces in MuSCs remains to be elucidated. In this study, we identified PIEZO1, a mechanosensitive ion channel that is activated by membrane tension, as a critical determinant for myofiber regeneration. more...

(Submitter supplied) Skeletal muscle stem cells (MuSCs) ensure the formation and homeostasis of skeletal muscle and are responsible for its growth and repair processes. For repair to occur, MuSCs must exit from quiescence, abandon their niche and asymmetrically and symmetrically divide to reconstitute the stem cell pool and give rise to muscle progenitors, respectively. The transcriptomes of pooled MuSCs have provided a rich source of information for describing the genetic programs underlying distinct static cell states; however, bulk microarray and RNA-seq afford only averaged gene expression profiles, which blur the heterogeneity and developmental dynamics of asynchronous MuSC populations. 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...
