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

Figure 7

M2 macrophage Exos enhanced HUVEC cell proliferation and inhibited HUVEC cell apoptosis in the HUVEC cell inflammatory injury model. (a, c) Cell apoptosis assay was determined using Annexin V-FITC/PI staining followed by flow cytometry (). (b) Cell proliferation was determined using CCK8 assay. HUVECs were treated with or without M0, M1, or M2 macrophage Exos (). (d) qRT-PCR analyses of inflammatory factors IL-6, IL-10, IL-1β, and TNF-α mRNA in HUVECs (). (e) Representative western blots of apoptosis-related protein (Caspase-3, Bcl2, and c-myc) expressions in HUVEC cells after Exos stimulation (). Compared with control group. , , .
