    TLDR Negative Pressure Wound Therapy speeds up wound healing by reducing inflammation and promoting skin cell growth.
    This study examines the early-stage molecular mechanisms of Negative Pressure Wound Therapy (NPWT) in a murine model, focusing on cytokine expression and hair follicle regeneration. NPWT accelerates wound healing by promoting early hemostasis and balancing inflammation, primarily through macrophage-mediated secretion of DKK-1. This protein aids in the differentiation of hair follicle stem cells (HFSCs) into epidermal cells, enhancing wound closure and re-epithelialization. Immunohistochemical analysis shows increased expression of hair follicle markers K14 and K15, indicating enhanced regeneration. Despite the study's 16-hour observation limitation, it provides valuable insights into NPWT's potential to improve therapeutic strategies for wound management.
