    TLDR Negative Pressure Wound Therapy speeds up wound healing by reducing inflammation and promoting skin cell growth.
    This study investigates the early-stage molecular mechanisms of Negative Pressure Wound Therapy (NPWT) using a C57BL/6JNarl mouse model. The research highlights NPWT's role in modulating inflammatory immune responses and orchestrating signal transduction pathways, leading to reduced inflammation and faster wound healing. A key finding is the increased concentration of dickkopf-related protein 1 (DKK-1) during NPWT, which promotes the differentiation of Hair Follicle Stem Cells (HFSCs) into epidermal cells, aiding wound closure. Macrophages under negative pressure release DKK-1 cytokines, crucial for HFSC differentiation. These insights provide a framework for enhancing wound healing and suggest potential for future pharmacological advancements in wound care.
