Abstract

Resolution-phase macrophage population orchestrates active dampening of the inflammation by secreting anti-inflammatory and proresolving products including interleukin (IL)-10 and lipid mediators. We investigated the effects of both human bone marrow-derived mesenchymal stromal cells (MSCs) and MSC-derived extracellular vesicles (MSC-EVs) on mature human regulatory macrophages (Mregs). The cytokines and lipid mediators were determined from cell culture media of Mregs cultivated with MSCs and MSC-EVs. Additionally, the alterations in the expression of cell surface markers and the phagocytic ability of Mregs were investigated. Our novel findings indicate that both MSC co-culture and MSC-EVs down-regulated the production of IL-23 and IL-22 enhancing the anti-inflammatory phenotype of Mregs and amplifying proresolving properties. The levels of prostaglandin E2 (PGE2) were substantially upregulated in MSC co-culture media, which may endorse proresolving lipid mediator class switching. Additionally, our results manifest, for the first time, that MSC-EVs mediate the Mreg phenotype change via PGE2. These data suggest that both human MSC and MSC-EVs may potentiate tolerance-promoting proresolving phenotype of human Mregs.

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

  • MSC-EVs mediate their action at least in part via PGE2.

    “The authors also demonstrated that MSC-EVs mediate their action, at least in part, via PGE2 (Table 1) [75].”

    From Mesenchymal stem cell secretome for regenerative medicine: Where do we stand? (2025) · cites this paper as [75]

    The Results (Table 3) show increased PGE2 in Mreg-conditioned media exposed to MSC-EVs, and the Introduction says MSC-EVs may mediate the observed cytokine changes via PGE2. The Discussion says this mechanism requires further study, so the paper does not demonstrate that EV action occurs via PGE2. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • BM-MSCs co-cultured with regulatory macrophages and MSC-EVs decrease the levels of IL-22 and IL-23 in macrophage-produced conditioned media.

    “Hyvarinen and co-workers have shown that BM-MSCs co-culture with regulatory macrophages and MSC-EVs decrease the levels of IL-22 and IL-23 in the macrophages-produced CM [75].”

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.
