Fig. 1From: Cancer-derived exosomes as novel biomarkers in metastatic gastrointestinal cancerThe mechanisms of CDEs in cancer metastasis. CDEs are involved in the processes of assistant tumors to depart from primary site, immune evasion, angiogenesis, increasing vascular permeability, the formation of pre-metastatic niche (PMN), epithelial-mesenchymal transition (EMT), planting on distant organs, and promoting cancer metastasisBack to article page
