Fig. 2. Exosomes derived from hypoxic breast cancer cells contributed to target cell viability and migration through delivering miR-25-3p. Normoxia, hypoxia, or hypoxia + miR-25-3p-derived exosomes were added into normoxia MDA-MB-231 and E0771 cells. About 48 h after incubation, the viability (A and B) and migration (C and D) of tumor cells were assessed by MTT and Transwell assays.
