Tobacco flavored e-cigs inhibited wound healing mediated by lung fibroblast

HFL-1 cells were scratched and then exposed to air, PG/VG, or tobacco flavored e-cig for 10 min, and then cultured for 2 days. The scratched wounds were monitored by taking pictures under the microscope daily. The same position has been selected by recording the coordinates from Cytation 5 imaging system. Data presented as mean ± SEM. (n = 11–12. * P < 0.05, ** P < 0.01, vs. air)
