Primary murine neutrophils were added to LMEC monolayer co-cultured with or without MSCs or EVs. b Exposure of LMECs to HR and cytomix (cyto; HMGB1 and TNF-α; 50 ng/ml each) for 4 h showed a significant increase in neutrophil transmigration, which was significantly attenuated by co-cultures with MSCs or EVs. n = 8/group; *, p < 0.05 vs. allBack to article page
