Abstract

Satellite cells, the predominant stem cell population in adult skeletal muscle, are activated in response to hypertrophic stimuli and give rise to myogenic progenitor cells (MPCs) within the extracellular matrix (ECM) that surrounds myofibers. This ECM is composed largely of collagens secreted by interstitial fibrogenic cells, which influence satellite cell activity and muscle repair during hypertrophy and aging. Here we show that MPCs interact with interstitial fibrogenic cells to ensure proper ECM deposition and optimal muscle remodeling in response to hypertrophic stimuli. MPC-dependent ECM remodeling during the first week of a growth stimulus is sufficient to ensure long-term myofiber hypertrophy. MPCs secrete exosomes containing miR-206, which represses Rrbp1, a master regulator of collagen biosynthesis, in fibrogenic cells to prevent excessive ECM deposition. These findings provide insights into how skeletal stem and progenitor cells interact with other cell types to actively regulate their extracellular environments for tissue maintenance and adaptation.

  • Satellite cell depletion appears to cause dysregulation in the surrounding muscle environment leading to increased fibrosis with ageing and reduced muscle quality and function.

    “While satellite cell depleted mice do not show signs of increased muscle loss, satellite cell depletion appears to cause a dysregulation in the surrounding muscle environment leading to increased fibrosis with ageing and a reduction in muscle quality and function.”
  • Satellite cells play an important role in maintenance of muscle mass with age by regulating extracellular matrix production during hypertrophy and regeneration.

    “Indeed, satellite cells have been implicated in regulating extracellular matrix production during hypertrophy and regenerative processes, and therefore do play an important role in the maintenance of muscle mass with age [26,30,31].”
  • Satellite cells play an integral role in regulating the extracellular matrix during remodeling.

    “While satellite cells play an integral role in regulating the extracellular matrix during remodeling [26,30,31], it is yet to be determined whether excessive extracellular matrix (ECM) accumulation or a “myonuclear domain ceiling” limits prolonged hypertrophy in the absence of satellite cells.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
