Exosomal miRNA in Cancer. a The first general mechanism is that cancer cells export exosomal miRNA to parent surrounding cancer cells. b The second general mechanism is that primary tumor cells can communicate with other cells via exosomal miRNAs in the tumor microenvironment. c The third general mechanism is that exosomes derived from normal cells alter the behavior of tumor cells. d The forth general mechanism is that exosomes derived from cells infected with virus to influencr normal cells oncology and themselves
