HO-ADSC exosomes promote human EOC cell proliferation, migration, and invasion (A2780, HO8910, SKOV3, and HEY) in vitro. (A). The influence of HO-ADSC exosomes on human EOC cell proliferation was measured by EdU assay. (B). The influence of HO-ADSC exosomes on human EOC cell migration was measured by Transwell assay. (C). The influence of HO-ADSC exosomes on human EOC cell invasion was measured by Transwell assay. (D). Quantification of proliferation rates showed that the proliferative capacity of human EOC cell lines was significantly improved when exposed to HO-ADSC exosomes. (E). Quantification of the migrating cells showed that the migratory capacity of human EOC cell lines was significantly improved when exposed to HO-ADSC exosomes. (F). Quantification of the invasion rates of human EOC cell lines showed that the invasive capacity of human EOC cell lines was significantly improved when exposed to HO-ADSC exosomes. * p < 0.05, n = 3.
