Abstract

Satellite cells are skeletal muscle stem cells capable of self-renewal and differentiation after transplantation, but whether they contribute to endogenous muscle fiber repair has been unclear. The transcription factor Pax7 marks satellite cells and is critical for establishing the adult satellite cell pool. By using a lineage tracing approach, we show that after injury, quiescent adult Pax7(+) cells enter the cell cycle; a subpopulation returns to quiescence to replenish the satellite cell compartment, while others contribute to muscle fiber formation. We demonstrate that Sprouty1 (Spry1), a receptor tyrosine kinase signaling inhibitor, is expressed in quiescent Pax7(+) satellite cells in uninjured muscle, downregulated in proliferating myogenic cells after injury, and reinduced as Pax7(+) cells re-enter quiescence. We show that Spry1 is required for the return to quiescence and homeostasis of the satellite cell pool during repair. Our results therefore define a role for Spry1 in adult muscle stem cell biology and tissue repair.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In MuSCs, the activation process is canonically characterized by expression of Myod1, loss of Spry1 and Pax7, and entry into the cell cycle.

    “In MuSCs, the activation process is canonically characterized by expression of Myod1 (Grounds et al., 1992; Yablonka-Reuveni and Rivera, 1994), loss of Spry1 and Pax7, and entry into the cell cycle (Shea et al., 2010).”

  • The quiescence marker Spry1 displayed a monotonic decrease with activation and Myod1 displayed a monotonic increase.

    “By contrast, the quiescence marker Spry1 (Shea et al., 2010) displayed a monotonic decrease with activation and Myod1 displayed a monotonic increase (Fig. 2G).”

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.
