Roles of exosomes from the BALF of mice exposed to NTHi lysate or air. (A) Cell proliferation assay was performed in LLC cells incubated with PBS, air-Exosor NTHi-Exos (n = 4). (B) Migration assay was performed in LLC cells co-cultured with PBS, air-Exos or NTHi-Exos (n = 10). (C) Invasion assay was performed in LLC cells co-cultured with PBS, air-Exos or NTHi-Exos (n = 10). Scar bar = 200 μm. Results are presented as means ± SEM of three independent experiments. (^*P < 0.05, ^**P < 0.01, ^***P < 0.001).
