Hypermongone C Accelerates Wound Healing through the Modulation of Inflammatory Factors and Promotion of Fibroblast Migration.

ABSTRACT: The physiology of wound healing is dependent on the crosstalk between inflammatory mediators and cellular components of skin regeneration including fibroblasts and endothelial cells. Therefore, strategies to promote healing must regulate this crosstalk to achieve maximum efficacy. In light of the remarkable potential of natural compounds to target multiple signaling mechanisms, this study aims to demonstrate the potential of hypermongone C, a polycyclic polyprenylated acylphloroglucinol (PPAP), to accelerate wound closure by concurrently enhancing fibroblast proliferation and migration, promoting angiogenesis, and suppressing pro-inflammatory cytokines. This compound belongs to a family of plants (Hypericum) that traditionally have been used to treat injuries. Nevertheless, the exact biological evidence to support the claims is still missing. The results were obtained using a traditional model of cell scratch assay and endothelial cell tube formation, combined with the analysis of protein and gene expression by macrophages. In summary, the data suggest that hypermongone C is a multi-targeting therapeutic natural compound for the promotion of tissue repair and the regulation of inflammation.

Project description:The application of blood plasma for soft tissue wound healing is receiving much more attention recently. Exosomes are critical paracrine mediators that can be obtained from biological fluids including plasma and be able to induce regenerative effects by transferring bioactive molecules such as microRNAs (miRNAs). This study aimed to investigate the effects of exosomes from human umbilical cord blood plasma (UCB-Exos) on wound healing and to elucidate the underlying mechanism. Methods: UCB-Exos were isolated by ultracentrifugation and subcutaneously injected into full-thickness skin wounds in mice. The efficacy of UCB-Exos on wound healing was evaluated by measuring wound closure rates, histological analysis and immunofluorescence examinations. In vitro, quantitative real-time PCR (qRT-PCR) analysis was performed to detect the expression levels of a class of miRNAs that have positive roles in regulating wound healing. The scratch wound assay, transwell assay and cell counting kit-8 analysis were conducted to assess the effects of UCB-Exos on migration and proliferation of human skin fibroblasts and endothelial cells. Tube formation assay was carried out to test the impact of UCB-Exos on angiogenic tube formation ability of endothelial cells. Meanwhile, by using specific RNA inhibitors or siRNAs, the roles of the candidate miRNA and its target genes in UCB-Exos-induced regulation of function of fibroblasts and endothelial cells were assessed. Results: The local transplantation of UCB-Exos into mouse skin wounds resulted in accelerated re-epithelialization, reduced scar widths, and enhanced angiogenesis. In vitro, UCB-Exos could promote the proliferation and migration of fibroblasts, and enhance the angiogenic activities of endothelial cells. Notably, miR-21-3p was found to be highly enriched in UCB-Exos and served as a critical mediator in UCB-Exos -induced regulatory effects through inhibition of phosphatase and tensin homolog (PTEN) and sprouty homolog 1 (SPRY1). Conclusion: Our results suggest that UCB-Exos are important effectors of plasma activity and can be used as a novel promising strategy for soft tissue wound healing.
