Impaired Migration following Wood Smoke Exposure. A549 cells were grown to confluent monolayers, scratched, and exposed to 5% and 10% WS for up to 48 hours. *P < 0.05 vs. 24 h 5% WS; †P < 0.001 vs. 24 h PBS; ‡P < 0.001 vs. 24 h and 48 h PBS, 24 h 5% WS, 48 h 5% WS; &P < 0.01 vs. 24 h 5% WS, 48 h PBS; φP < 0.001 vs. 48 h PBS; ΨP < 0.01 vs. 24 h 5% WS; n = 3. Statistical differences were determined using a two-way ANOVA followed by a Tukey’s post-hoc test. Data presented as mean ± se.
