Efficacy of Human Adipose Derived Mesenchymal Stem Cells in Promoting Skin Wound Healing

BACKGROUND: The aim of this pilot clinical study is to evaluate the efficacy of human adipose derived mesenchymal stem cells (HAMSCs) treatment for the wound healing with patients. METHODS: This study was a clinical trial to investigate the efficacy of human adipose derived mesenchymal stem cells treatment for the wound healing with patients. 346 patients with skin wounds attending the central hospital of Yue Yang were enrolled in the study, setting in the period from January 2016 to January 2021. Patients were randomly allocated into two groups: experimental group received treatment with human adipose derived mesenchymal stem cells for each 10 cm(2) of wound and control group received conventional dressing with normal saline for each 10 cm(2) of wound. RESULTS: No adverse events were recorded during the period of treatment. The granulation tissue coverage rate and thickness of granulation tissue after 10 days of treatment in experimental group were significantly improved compared with control group. Furthermore, the occurrence of bleeding of wound and suppurative wounds between two groups had significant difference (P < 0.05). CONCLUSION: The data in this pilot study indicated that human adipose derived mesenchymal stem cells may be a safe and effective alternative therapy for wound healing. Moreover, larger, placebo-controlled, perspective studies are necessity to evaluate the efficacy and safety of human adipose derived mesenchymal stem cells treatment for wound healing patients.
