A Biomimetic Hierarchical Nanointerface Orchestrates Macrophage Polarization and Mesenchymal Stem Cell Recruitment To Promote Endogenous Bone Regeneration
Abstract
The host immune response to bone biomaterials is vital in determining scaffold fates and bone regeneration outcomes. The nanometer-scale interface of biomaterials, which independently controls physical inputs to cells, regulates osteogenic differentiation of stem cells and local immune response. Herein, we fabricated biomimetic hierarchical intrafibrillarly mineralized collagen (HIMC) with a bone-like staggered nanointerface and investigated its immunomodulatory properties and mesenchymal stem cell (MSC) recruitment during endogenous bone regeneration. The acquired HIMC potently induced neo-bone formation by promoting CD68 + CD163 + M2 macrophage polarization and CD146 + STRO-1 + host MSC recruitment in critical-sized bone defects. Mechanistically, HIMC facilitated M2 macrophage polarization and interleukin (IL)-4 secretion to promote MSC osteogenic differentiation. An anti-IL4 neutralizing antibody significantly reduced M2 macrophage-mediated osteogenic differentiation of MSCs. Moreover, HIMC-loaded-IL-4 implantation into critical-sized mandible defects dramatically enhanced bone regeneration and CD68 + CD163 + M2 macrophage polarization. The depletion of monocyte/macrophages by clodronate liposomes significantly impaired bone regeneration by HIMC, but did not affect MSC recruitment. Thus, in emulating natural design, the hierarchical nanointerface possesses the capacity to recruit host MSCs and promote endogenous bone regeneration by immunomodulation of macrophage polarization through IL-4.

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.
