Negative Pressure Wound Therapy NPWT dickkopf-related protein 1 DKK-1 Hair Follicle Stem Cells HFSCs epidermal cells macrophages cytokines

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.
