MiR-9-5p dictates drug resistance conferred by exosomes isolated from MCF-7/TAM cells in the parental MCF-7 cells. a The viability of MCF-7 recipient cells after co-culture with (MCF-7 + miR-9-5p mimic)-exo or (MCF-7/TAM + miR-9-5p inhibitor)-exo determined by CCK-8. b The quantitation of IC50 of MCF-7 recipient cells after co-culture. c Flow cytometric detection of the apoptosis of MCF-7 recipient cells after co-culture with (MCF-7 + miR-9-5p mimic)-exo or (MCF-7/TAM + miR-9-5p inhibitor)-exo. *p <0.05. Each experiment was conducted three times independently
