Abstract

PURPOSE OF REVIEW: Skeletal muscle development serves as a paradigm for cell lineage specification and cell differentiation. Adult skeletal muscle has high regenerative capacity, with satellite cells the primary source of this capability. The present review describes recent findings on developmental and adult myogenesis with emphasis on emerging distinctions between various muscle groups and stages of myogenesis. RECENT FINDINGS: Muscle progenitors of the body are derived from multipotent cells of the dermomyotome and express the transcription factors Pax3 and Pax7. These cells self-renew or induce expression of myogenic regulatory factors (MRFs) and differentiate. The roles of Pax3, Pax7 and specific myogenic regulatory factor progenitor populations in trunk and limb myogenesis have been identified through cell ablation in the mouse. Various head muscles and associated satellite cells have differing developmental origins, and rely on distinct combinations of transcriptional regulators, than trunk and limb muscles. Several genetic and sorting protocols demonstrate that satellite cells are heterogeneous with some possessing stem cell properties; the relative roles of lineage and niche in these properties are being explored. Although cellular mechanisms of developmental, postnatal and adult regenerative myogenesis are thought to be similar, recent studies reveal distinct genetic requirements for embryonic, fetal, postnatal and adult regenerative myogenesis. SUMMARY: Genetic determinants of formation or repair of various muscles during different stages of myogenesis are unexpectedly diverse. Future studies should illuminate these differences, as well as mechanisms that underlie stem cell properties of satellite cells.

  • Muscle injury activates satellite cells to regenerate muscle by releasing IGF1, fibroblast growth factor and mechano growth factor, which stimulate satellite cell differentiation and proliferation.

    “Muscle injury activates satellite cells to regenerate muscle by releasing IGF1, fibroblast growth factor and mechano growth factor, all of which stimulate the differentiation and proliferation of muscle satellite cells112,113.”

    From Sarcopenic obesity in older adults: aetiology, epidemiology and treatment strategies (2018) · cites this paper as [112]

    The Satellite cell heterogeneity section (page unavailable) says muscle injury activates satellite cells to proliferate and differentiate during regeneration. It does not say injury releases IGF1, fibroblast growth factor, or mechano growth factor to stimulate those cells; its discussion of FGF concerns embryonic progenitors instead. (LLM, conf=0.88)

  • Muscle protein synthesis is also improved by nutrient-stimulated vasodilation and nutrient transport to local muscle myofibrils.

    “Muscle protein synthesis is also improved by nutrient-stimulated vasodilation and nutrient transport to local muscle myofibrils112,124.”

    From Sarcopenic obesity in older adults: aetiology, epidemiology and treatment strategies (2018) · cites this paper as [112]

    The Introduction and Conclusion describe muscle stem cells, development, and regeneration. A passage in “Satellite cell heterogeneity” discusses signaling between nearby cells and satellite cells, but not nutrient-stimulated vasodilation, nutrient transport to myofibrils, or muscle protein synthesis. Searches for those terms found no passage addressing the claimed mechanism; page numbers were not available in our copy. (LLM, conf=0.76)

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.
