Effect of Conj-MSC-derived EVs on conjunctival epithelial cells. (A) Effect of EVs on oxidative stress produced by exposure to H2O2. EVs significantly reduced the increase in reactive oxygen species (ROS) induced by H2O2. * Indicates significance compared to untreated cells, and # compared to untreated cells exposed to H2O2. (B) Cell viability measured with AlamarBlue assay. No significant differences were observed after EV treatment (n = 3).
