Cell viability of EV treatment under OGD conditions. (A) HT-22 cells were observed by microscopy after treatment with A-EVs of B-EVs. A-EVs and B-EVs alleviated OGD-induced decreases in cell viability and apoptosis. (B) The cell viability was determined with A-EV or B-EV treatment in OGD cells. All experiments were repeated at least three times. *** p < 0.001 and **** p < 0.0001 compared with the OGD group.
