Abstract

Efficient muscle regeneration requires cross talk between multiple cell types via secreted signaling molecules. However, as yet there has been no comprehensive analysis of this secreted signaling network in order to understand how it regulates myogenesis in humans. Using integrated proteomic and genomic strategies, we show that human muscle cells release not only soluble secreted proteins through conventional secretory mechanisms but also complex protein and nucleic acid cargos via membrane microvesicle shedding. The soluble secretome of muscle cells contains 253 conventionally secreted signaling proteins, including 43 previously implicated in myogenesis, while others are known to modulate various cell types thus implying a much broader role for myoblasts in muscle remodeling. We also isolated and characterized two types of secreted membrane-derived vesicles: nanovesicles harboring typical exosomal features and larger, morphologically distinct, microvesicles. While they share some common features, their distinct protein and RNA cargos suggest independent functions in myogenesis. We further demonstrate that both types of microvesicles can dock and fuse with adjacent muscle cells but also deliver functional protein cargo. Thus, the intercellular signaling networks invoked during muscle differentiation and regeneration may employ conventional soluble signaling molecules acting in concert with muscle derived microvesicles delivering their cargos directly into target cells.

Claims other papers make about this one

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

  • MPs were enriched in genes coding for proteins involved in protein synthesis, folding, and trafficking, RNA post-transcriptional modifications, translation modifications, and amino acid metabolism.

    “MPs were enriched in genes coding for proteins involved in “protein synthesis, folding, and trafficking,” “RNA post-transcriptional modifications,” “translation modifications,” and “amino acid metabolism.””

  • Muscle cells release extracellular vesicles into the extracellular milieu, which represent new paracrine and endocrine signals.

    “During the last decade, it has been shown that muscle cells also release extracellular vesicles (EVs) into the extracellular milieu, which represent new paracrine and endocrine signals that have modified our conceptual basis to explain how muscles communicate to other organs (Guescini et al., 2010; Le Bihan et al., 2012; Romancino et al., 2013; Forterre et al., 2014a).”

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.
