Diabetic foot ulcers (DFUs) are a common and serious complication of diabetes, often leading to amputation and decreased quality of life. Current treatment methods have limited success rates, highlighting the need for new approaches. This study investigates the potential of tibial transverse transport (TTT) to promote wound healing in DFUs. ⋯ TTT significantly enhanced wound healing in diabetic rabbit foot ulcers. Specifically, bilateral TTT led to complete wound healing by day 19, faster than the unilateral TTT group, which healed by day 26, and the sham operation group, which nearly healed by day 37. Histological analysis showed improved tissue architecture, collagen deposition, and neovascularization in TTT-treated groups. Furthermore, TTT treatment resulted in a significant increase in VEGFR2 expression and VEGFR2/Tie-2 positive cells, particularly in the bilateral group. These findings were corroborated by qPCR results, which showed increased expression of VEGFA and CXCL12 by TTT. Conclusions: TTT may be a promising treatment for DFUs, significantly enhancing wound healing by stimulating EPC mobilization and homing mediated angiogenesis. This novel approach could substantially improve treatment outcomes for diabetic patients with chronic foot ulcers.
