Abstract

Mesenchymal stem cells (MSCs) have been described as being able to give rise to several quite different mesenchymal cell phenotypes. However, the ability to differentiate is not the only characteristic that makes these cells attractive for therapeutic purposes. The secretion of a broad range of bioactive molecules by MSCs, such as growth factors, cytokines and chemokines, constitutes their most biologically significant role under injury conditions. Understanding this intricate secretory activity as well as the properties of MSCs in vivo is central to harnessing their clinical potential. Herein, we identify some of the molecules involved in the paracrine effects of MSCs with a perspective that these cells intrinsically belong to a perivascular niche in vivo, and discuss how this knowledge could be advantageously used in clinical applications.

  • IL-6 is an MSC-secreted inflammatory cytokine with pro-survival, pro-growth and pro-angiogenic activities, and it has been implicated in tumor progression in various cancers including breast cancer.

    “IL-6 is an MSC-secreted inflammatory cytokine displaying pro-survival, pro-growth and pro-angiogenic activities [11], which has been implicated in tumor progression of various cancers including breast cancer [113, 114].”

    From Mesenchymal stem cell secretome and regenerative therapy after cancer (2013) · cites this paper as [11]

    Section 3.2.4 says cultured MSCs secrete IL-6 as part of their support for hematopoiesis, and Section 3.2.5 and Table 1 classify it among angiogenic factors. Section 3.2.5 describes anti-apoptotic effects of MSC-conditioned medium containing IL-6, but does not establish IL-6 itself as the cause or clearly establish its individual pro-growth activity. The tumor-progression clause is cited to [113, 114], not to this source, and is not part of this verdict. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Most MSC-secreted factors form a common core regardless of tissue origin, including overlapping anti-apoptotic, immunomodulatory, anti-scarring, supportive, angiogenic and chemoattractant factors such as IL6, CCL2, PAI-1, TGFβ1, CD106 and VEGF.

    “The bulk of MSC-secreted factors comprises a common core, independently of their tissue of origin, including an overlapping set of anti-apoptotic, immunomodulatory, anti-scarring, supportive, angiogenic and chemoattractant factors such as interleukin-6 (IL6), chemokine C-C motif ligand 2 (CCL2), PAI-1, transforming growth factor-beta1 (TGFβ1), CD106 and vascular endothelial growth factor (VEGF) [”

    From Mesenchymal stem cell secretome and regenerative therapy after cancer (2013) · cites this paper as [11]

    Table 1 (section 4, page unavailable) lists the six functional categories and includes IL-6, CCL2, TGF-β and VEGF among factors associated with cultured MSCs. It does not establish that most secreted factors form a common core independent of tissue origin, and it does not list PAI-1 or CD106 as secreted factors. (LLM, conf=0.88)

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.
