ABSTRACT
Tumor angiogenesis plays an important role in the development of cancer as it allows the delivery of oxygen, nutrients, and growth factors as well as tumor dissemination to distant organs. Although anti-angiogenic therapy (AAT) has been approved for treating various advanced cancers, this potential strategy has limited efficacy due to resistance over time. Therefore, there is a critical need to understand how resistance develops. Extracellular vesicles (EVs) are nano-sized membrane-bound phospholipid vesicles produced by cells. A growing body of evidence suggests that tumor cell-derived EVs (T-EVs) directly transfer their cargoes to endothelial cells (ECs) to promote tumor angiogenesis. Importantly, recent studies have reported that T-EVs may play a major role in the development of resistance to AAT. Moreover, studies have demonstrated the role of EVs from non-tumor cells in angiogenesis, although the mechanisms involved are still not completely understood. In this review, we provide a comprehensive description of the role of EVs derived from various cells, including tumor cells and non-tumor cells, in tumor angiogenesis. Moreover, from the perspective of EVs, this review summarized the role of EVs in the resistance to AAT and the mechanisms involved. Due to their role in the resistance of AAT, we here proposed potential strategies to further improve the efficacy of AAT by inhibiting T-EVs.
