a, b MTT assay showed that E/M@FA-LPs inhibited the viability of A549 and H1299 cells. c E/M@FA-LPs inhibited A549 and H1299 cell proliferation by EdU assay. Scale bar represents 25 μm. d Effect E/M@FA-LPs on cell migration in A549 cell; the migration of tumor cells to acellular areas is not obvious. Scale bar represents 100 μm. e Effect E/M@FA-LPs on cell invasion in A549 cell. Scale bar represents 25 μm. All experiments were repeated at least three times and representative data are shown. Data are means ± SEM; **p < 0.01.
