Dysregulated macrophage function is a key factor in delayed wound healing. Recent studies have emphasized the therapeutic potential of macrophage-derived extracellular vesicles (MDEVs), which are enriched with bioactive molecules such as proteins, lipids, and nucleic acids that mirror the state of their parent cells. MDEVs influence immune modulation, angiogenesis, extracellular matrix remodeling, and intercellular communication. In this review, we summarize and discuss the biological properties and therapeutic mechanisms of MDEVs in diabetic wound healing, highlighting strategies to enhance their efficacy through bioengineering and advanced delivery systems. We also explore the integration of MDEVs into innovative wound care technologies. Addressing current limitations and advancing clinical translation of MDEVs could advance diabetic wound management, offering a precise, effective, and versatile therapeutic option.Keywords: extracellular vesicle, diabetic wound, macrophage, nanomedicine, therapy
