NSCLC serum-derived exosomes promoted NSCLC cell malignant behaviors in vitro. a A549 and H460 cells were co-cultured with NSCLC serum-derived exosomes, with exosomes-depleted serum as the control. In these co-cultured cells, b, c cell cycle was detected by flow cytometry. d The ability of colony formation was assessed by colony formation assay. e, f Cell proliferation was assessed by MTT assay. g, h Cell migration and cell invasion were investigated using transwell assay. i, j The expression of E-cadherin, N-cadherin and Vimentin was determined by western blot. k Cell apoptosis was monitored by flow cytometry assay. *P < 0.05
