Individuals with diabetes mellitus (DM) experience impaired wound healing, where the healing process is often compromised by a complex, hostile microenvironment characterized by persistent inflammation, high oxidative stress, and dysfunctional angiogenesis. The hyperglycemic environment damages the blood vessels and disturbs the normal hypoxia-induced upregulation of vascular endothelial growth factors, causes poor vascularization and insufficient production of new blood vessels, and leads to impaired perfusion and thickened and dysfunctional capillary basement membranes, which reduce blood flow to the wound, leading to delayed wound healing. Mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs) are the main effectors of intercellular communication and have emerged as a potent cell-free strategy for the acceleration of tissue repair. MSC-EVs can be isolated from various adult tissues, but increasing evidence suggests that pla
