Abstract

Multipotent mesenchymal stromal cells (MSC) have been widely explored for cell-based therapy of immune-mediated, inflammatory, and degenerative diseases, due to their immunosuppressive, immunomodulatory, and regenerative potentials. Preclinical studies and clinical trials have demonstrated promising therapeutic results although these have been somewhat limited. Aspects such as low in vivo MSC survival in inhospitable disease microenvironments, requirements for ex vivo cell overexpansion prior to infusions, intrinsic differences between MSC and different sources and donors, variability of culturing protocols, and potency assays to evaluate MSC products have been described as limitations in the field. In recent years, priming approaches to empower MSC have been investigated, thereby generating cellular products with improved potential for different clinical applications. Herein, we review the current priming approaches that aim to increase MSC therapeutic efficacy. Priming with cytokines and growth factors, hypoxia, pharmacological drugs, biomaterials, and different culture conditions, as well as other diverse molecules, are revised from current and future perspectives.

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

  • The immunoregulatory role of MSCs is stimulated in the presence of one or more cytokines, such as IFN-γ, IL-1α, IL-1β or TNF-α, all released by macrophages.

    “The immunoregulatory role of MSCs was shown to be stimulated in the presence of one or more cytokines, such as IFN-γ, IL-1α, IL-1β or TNF-α, all released by macrophages [133], [134], [135].”

    From Mesenchymal stem cell secretome for regenerative medicine: Where do we stand? (2025) · cites this paper as [134]

    The Background and cytokine-priming sections (page unavailable) report enhanced MSC immunomodulatory activity after exposure to IFN-γ, TNF-α, IL-1β, and, in one priming study, IL-1α. The copy does not say that macrophages release all four cytokines; its macrophage passages instead describe macrophages arising or changing in response to primed MSCs. (LLM, conf=0.88)

  • Priming is induced by cytokines, chemokines, growth factors, lipid-derived signalling molecules and physical cell-cell contact and adhesion.

    “Priming is induced by cytokines, chemokines, growth factors, lipid-derived signalling molecules and physical cell–cell contact and adhesion [217].”
  • Priming occurs at almost all levels of neutrophil function: adhesion, phagocytosis, cytokine secretion, leukotriene synthesis and degranulation.

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.
