肿瘤的生长与转移依赖于充足的血管生成以及血液供养，越来越多的研究证实肿瘤来源的外泌体参与促进肿瘤血管新生。本文通过综述外泌体如何驱动血管新生，为改进现有的抗血管生成疗法增加新的选择。

Tumor growth and metastasis depend on adequate angiogenesis and blood supply. More and more studies have confirmed that tumor drived exosomes are involved in promoting tumor angiogenesis. This article reviews how exosomes drive angiogenesis to add new options for improving existing antiangiogenic therapies.
