Fig. 4. Radon exposure promotes cell migration. (A) A wound healing assay was used to detect the migration ability of BEAS-2B cells after radon exposure. Representative cell images from each indicated times of exposure group in the are shown. (B) Quantification of wound healing is shown. Results are expressed as means ± SD (n = 4). (*p < 0.05 indicated times of radon exposure vs. control group).
