Abstract (original English)

Background Diabetic foot ulcers (DFUs) are a severe complication of diabetes and a leading cause of lower limb amputation due to impaired wound healing. Adipose-derived mesenchymal stem cells (ADSCs) have emerged as a promising therapeutic option for DFUs because of their angiogenic, immunomodulatory, and regenerative properties. However, studies on the molecular mechanisms and regulatory pathways of ADSCs in DFUs are limited. Aim To investigate the dose-response relationship, the optimal administration route, persistence, and molecular mechanisms of ADSCs in DFU healing. Methods In this study, human ADSCs were isolated and cultured, and their differentiation potential was characterized. A DFU mouse model was established to evaluate the dose-dependent effects and persistence of ADSCs administered subcutaneously or intramuscularly. Wound closure rate, angiogenesis, inflammation, and collagen deposition were assessed in the ADSC-treated and model groups. Additionally, in vitro experiments using human dermal fibroblasts and endothelial cells were conducted to elucidate the molecular mechanisms underlying ADSC-mediated wound healing. Results ADSC treatment significantly enhanced wound closure, promoted angiogenesis, modulated inflammatory responses, and accelerated tissue regeneration in the DFU model. Notably, the therapeutic efficacy and retention of ADSCs were influenced by both
