Abstract

Cells of the mononuclear phagocytic system including monocytes and macrophages (e.g., pooled human monocytes, bone marrow‐derived macrophages, etc.) are often employed for in vitro assessment of novel biomaterials and to assay anti‐inflammatory drug activity. In this context, numerous macrophage cells are treated interchangeably in the literature despite a lack of demonstrated equivalence among immortalized cell lines and further, between cell lines and primary‐derived macrophages of different species. Three murine (monocyte‐) macrophage cell lines (IC‐21, J774A.1, and RAW 264.7), commonly utilizedin biomaterial and pharmaceutical screening research, have been compared with primary‐derived murine bone marrow macrophages. Significant differences were discovered in the expression of cell surface proteins requisite for cell adhesion and activation among cell lines and primary‐derived cells as well as between the different cell lines. Results demonstrate activation but with reduced cytokine expression to chemical stimulus (lipopolysaccharide) by cell lines compared with that of primary‐derived macrophages. Limited correlation between cultured primary and immortalized cells in cytokine production, phenotype and intrinsic activation states has relevance to fidelity for in vitro testing. These differences warrant justification for selection of various cell lines for specific assay purposes, and merit caution if comparisons to primary cell types (i.e., for biocompatibility) are required. © 2008 Wiley Periodicals, Inc.

  • Several physical factors of ECMs, including stiffness and topography, influence macrophage polarization and determine outcomes of wound healing and tissue remodeling.

    “Several physical factors of ECMs have been evidenced to influence macrophages polarization and determine the outcomes of wound healing and tissue remodeling, including stiffness, topography and so on [[27], [28], [29]].”

    From Substrate stiffness modulates bone marrow-derived macrophage polarization through NF-κB signaling pathway (2020) · cites this paper as [28]

    The section on cytokine mRNA expression on different surfaces reports that material type affected some macrophage cytokine responses in vitro. The studied surfaces were model biomaterials, however, and the paper does not establish that ECM stiffness or topography influences macrophage polarization or determines wound-healing and tissue-remodeling outcomes. Page numbers were not available in our copy. (LLM, conf=0.86)

  • MΦ cell lines are not functionally equivalent to primary MΦs.

    “While MΦ cell lines are useful and easy to manipulate, they are not functionally equivalent to primary MΦs [25].”

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.
