Core Tip
Core Tip: Although mesenchymal stem cells (MSCs) can be isolated and expanded from a variety of tissues, their regenerative efficacy for diabetic foot ulcers (DFUs) exhibits significant source-dependent variation, and the specific regulatory mechanisms involved remain incompletely understood. Cao et al demonstrated that subcutaneous injection of 5 × 105 adipose-derived stem cells (ADSCs) into the foot yielded the most effective wound healing outcomes for DFUs. Further angiogenesis experiments revealed that ADSCs promote blood vessel formation by activating the PI3K-AKT pathway to enhance VEGF secretion. Additionally, it was confirmed that ADSCs can suppress the overactivated Notch signaling pathway, thereby reducing local inflammatory responses and improving collagen deposition. This study not only elucidates the underlying molecular mechanisms by which ADSCs accelerate DFU healing but also provides critical evidence to support the clinical application of MSCs.
