Abstract

Macrophages play a crucial role in all stages of cutaneous wound healing responses and dysregulation of macrophage function can result in derailed wound repair. The phenotype of macrophages is influenced by the wound microenvironment and evolves during healing from a more pro-inflammatory (M1) profile in early stages, to a less inflammatory pro-healing (M2) phenotype in later stages of repair. The aim of the current study was to investigate the potential of exogenous administration of M2 macrophages to promote wound healing in an experimental mouse model of cutaneous injury. Bone marrow derived macrophages were stimulated in-vitro with IL-4 or IL-10 to obtain two different subsets of M2-polarized cells, M2a or M2c respectively. Polarized macrophages were injected into full-thickness excisional skin wounds of either C57BL/6 or diabetic db/db mice. Control groups were injected with non-polarized (M0) macrophages or saline. Our data indicate that despite M2 macrophages exhibit an anti-inflammatory phenotype in-vitro, they do not improve wound closure in wild type mice while they delay healing in diabetic mice. Examination of wounds on day 15 post-injury indicated delayed re-epithelialization and persistence of neutrophils in M2 macrophage treated diabetic wounds. Therefore, topical application of ex-vivo generated M2 macrophages is not beneficial and contraindicated for cell therapy of skin wounds.

  • Timing of release is crucial where, especially in older organisms, the balance between M1 and M2 polarization may be dysregulated and impairs wound healing.

    “Timing of release is crucial where, especially in older organisms, the balance between M1 and M2 polarization may be dysregulated and impairs wound healing.[ 223 ]”

    From Unraveling and Harnessing the Immune Response at the Cell–Biomaterial Interface for Tissue Engineering Purposes (2024) · cites this paper as [223]

    The Introduction (page unavailable) links an incomplete M1-to-M2 switch to chronic non-healing wounds, and the Discussion (page unavailable) suggests that administering M2 macrophages during the early inflammatory phase may disrupt a balance needed for healing. The paper does not establish this specifically in older organisms or test the timing of a controlled release. (LLM, conf=0.86)

  • Addition of macrophages induced with IL-4 or IL-10 delays wound healing in db/db mice.

    “It is also consistent with the observation that the addition of macrophages induced with IL-4 or IL-10 delays wound healing in db/db mice.107”

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.
