miR-200b regulated ovarian cancer cell proliferation and invasion through affecting macrophage polarization. M0 macrophages were transfected with nothing, mimic NC or miR-200b mimic. Then, the culture medium of macrophages were collected and then were used to culture ovarian cancer cells. At 24 h later of incubation, a CCK-8 assay was carried out to detect the cell viability of the cancer cells. b Transwell invasion assay was utilized to examine the invasion of cancer cells. *P < 0.05 compared with PBS. ^#P < 0.05 contrasted with M0^{mimic NC}
