Abstract

Aging of an organism is associated with the functional decline of tissues and organs, as well as a sharp decline in the regenerative capacity of stem cells. A prevailing view holds that the aging rate of an individual depends on the ratio of tissue attrition to tissue regeneration. Therefore, manipulations that favor the balance towards regeneration may prevent or delay aging. Skeletal muscle is a specialized tissue composed of postmitotic myofibers that contract to generate force. Satellite cells are the adult stem cells responsible for skeletal muscle regeneration. Recent studies on the biology of skeletal muscle and satellite cells in aging have uncovered the critical impact of systemic and niche factors on stem cell functionality and demonstrated the capacity of aged satellite cells to rejuvenate and increase their regenerative potential when exposed to a youthful environment. Here we review the current literature on the coordinated relationship between cell extrinsic and intrinsic factors that regulate the function of satellite cells, and ultimately determine tissue homeostasis and repair during aging, and which encourage the search for new anti‐aging strategies.

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

  • MuSC numbers remain largely stable until a geriatric age beyond 26 months.

    “Indeed MuSC numbers do not decrease appreciably until a highly advanced ‘geriatric’ age (>26 months) as determined by scoring of MuSCs in their anatomically defined niche in muscle tissue sections52,53.”
  • Sarcopenia is associated with increased apoptosis and reduced muscle regeneration, leading to muscle wasting.

    “Sarcopenia, is associated with increased levels of apoptosis (47) and reduced capabilities for muscle regeneration (41) leading to muscle wasting.”

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.
