(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) Adult muscle stem cells (MuSC) are quiescent with a localization between myofibers and basal lamina. Upon injury, MuSC exit quiescence, reenter cell cycle, expand and differentiate for muscle regeneration. By using genetic mouse model, we identified p110α/mTORC1 signaling as a indispensable pathway that permits quiescence exit and cell cycle reentry. In order to dig out the downstream effectors, we compared the transcriptome of freshly isolated MuSC from Ctrl (p110α-f/+:R26-YFP/YFP:Pax7-CreER/CreER) to MuSC-specific p110α-null (iKO, p110α-f/f:R26-YFP/YFP:Pax7-CreER/CreER) mice by RNA-sequencing, and AP1 target genes were dramatically down-regulated in iKO MuSC. more...

(Submitter supplied) Adult muscle stem cells (MuSCs) transit from a quiescent state to a highly proliferative state to support muscle repair. Paxbp1 deletion in MuSCs blocked their cell cycle re-entry and caused subsequent muscle regeneration failures. To understand the underlying molecular mechanisms, we compared the transcriptomes of control and Paxbp1 mutant MuSCs by RNA-seq. Our data confirmed a marked repression of cell cycle machineries in Paxbp1 mutant MuSCs. more...

(Submitter supplied) We previously showed that STAT3 regulates myoblast differentiation in cell culture models, yet its role in adult muscle satellite cells (MuSC) in vivo was less well characterized. When Stat3 was conditionally deleted in MuSC, muscle development and adult MuSC formation were not affected. However, with repeated muscle injuries, the number of the quiescent MuSC in STAT3-null mice decreased and the regeneration was delayed, suggesting defective MuSC maintenance. 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) 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) Skeletal muscle possesses the ability to adapt its size in response to milieus, which is called plasticity. Overload like resistance training induces the increment of muscle mass called muscle hypertrophy. Muscle stem cells (also known as muscle stem cells) function to supply new nuclei for myofiber during the overload in muscle. Using compensatory hypertrophy in plantaris muscles, we isolated MuSCs from plantaris muscles 4 days after surgery. more...

(Submitter supplied) Adult skeletal muscle regeneration is mainly driven by muscle stem cells (MuSCs), which are highly heterogeneous. Although recent studies have started to characterize the heterogeneity of MuSCs, whether a subset of cells with distinct exists within MuSCs remains unanswered. Here, we found that a population of MuSCs, marked by Gli1 expression, is required for muscle regeneration. The Gli1+ MuSC population displayed advantages in proliferation and differentiation both in vitro and in vivo. more...

Collagen V functions as a surrogate ligand for CalcR, and Protein kinase A (PKA)-mediated Yap1 suppression serve as the downstream of CalcR in quiescent muscle stem cells (Nature. 2018 May;557(7707):714-718, Cell Rep. 2019 Nov 19;29(8):2154-2163.e5.). 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...
