Abstract

Cutaneous wound healing affecting millions of people worldwide represents an unsolvable clinical issue that is frequently challenged by scar formation with dramatical pain, impaired mobility and disfigurement. Herein, we prepared a kind of light-sensitive decellularized dermal extracellular matrix-derived hydrogel with fast gelling performance, biomimetic porous microstructure and abundant bioactive functions. On account of its excellent cell biocompatibility, this ECM-derived hydrogel could induce a marked cellular infiltration and enhance the tube formation of HUVECs. In vivo experiments based upon excisional wound splinting model showed that the hydrogel prominently imparted skin wound healing, as evidenced by notably increased skin appendages and well-organized collagen expression, coupled with significantly enhanced angiogenesis. Moreover, the skin regeneration mediated by this bioactive hydrogel was promoted by an accelerated M1-to-M2 macrophage phenotype transition. Consequently, the decellularized dermal matrix-derived bioactive hydrogel orchestrates the entire skin healing microenvironment to promote wound healing and will be of high value in treatment of cutaneous wound healing. As such, this biomimetic ddECMMA hydrogel provides a promising versatile opinion for the clinical translation.

  • Studies on maxillofacial skin defect models have demonstrated that growth factor-loaded PDA hydrogels markedly promote angiogenesis and epithelialization, resulting in high-quality tissue repair outcomes.

    “In particular, studies on maxillofacial skin defect models have demonstrated that growth factor–loaded PDA hydrogels markedly promote angiogenesis and epithelialization, resulting in high-quality tissue repair outcomes.57”

    The Results and discussion sections on wound healing and angiogenesis report faster epithelial wound closure and increased vascularization with ddECMMA hydrogel; the Conclusion describes scar-free repair. But the model was rat full-thickness skin wounds, not maxillofacial defects, and the tested material was a dermal-matrix-derived ddECMMA hydrogel with retained growth factors, not a growth factor-loaded PDA hydrogel. Page numbers are unavailable in our copy. (LLM, conf=0.88)

  • Cell culture, antibacterial adhesion assays, and mucosal/wound healing models indicate that PDA-based coatings or hydrogels can improve wet adhesion, antioxidative protection, localized drug delivery, inflammation regulation, and wound healing.

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.
