Fig. 2: SiO2 induces the proliferation and migration of MML1 cells.

a Representative images of immunocytochemical staining show that SiO2 (50 μg/cm2) decreases PECAM 1/CD31 expression and increases α-SMA/Acta2 expression in MML1 cells. b MTT assay showing the SiO2-induced increase in the viability of MML1 cells. *P < 0.05 vs. the 0-h group, n = 5. c Representative images showing the effects of SiO2 on GFP-labeled MML1 cell migration in scratch assays. Scale bar = 80 µm. d Quantification of the scratch gap distances in six separate experiments. *P < 0.05 vs. the control group at the corresponding time point
