Figure 6. Effects of exosomal miR-584-5p on the cell viability and apoptosis of HMC3 cells. (A) The cell viability of HMC3 cells treated with POCD-derived exosomes and miR-584-5p mimics determined using Cell Counting Kit-8. (B) Flow cytometer was utilized to determine the cell apoptosis of HMC33 cells with different treatments. *: P < 0.05, compared with the control group. #: P < 0.05, compared with the Exos group.
