M2 Macrophage-Derived Exosomes Inhibit Apoptosis of HUVEC Cell through Regulating miR-221-3p Expression

Characterization of M0, M1, and M2 macrophages. (a) M0, M1, and M2 macrophages were induced by 100 μg/L PMA for 48 h, and the cellular morphology was observed under a light microscope, scale bar: 50 μm (). (b) Macrophages were identified by western blotting using anti-iNOS, anti-IL-12, anti-Arg1, and anti-CD206 antibodies (). (c) Levels of iNOS, IL-12, Arg1, and CD206 protein expression in macrophages. Compared with M0 group; ; ^#compared with M2 group; ^###.
