From: Tumor-associated exosomes promote lung cancer metastasis through multiple mechanisms
Tumor-derived exosomes promote cancer metastasis. Tumor-derived exosomes through multiple mechanisms participate in cancer metastasis by reshaping the tumor microenvironment; promoting cellular epithelial–mesenchymal transformation (EMT); promoting cell proliferation, inhabiting apoptosis; immunosuppression; promoting hematogenous metastasis and angiogenesis of metastasitic tumor to promote cancer metastasis
