Figure 6
(A) Changes in nuclear morphology of A549 cells were detected by Hoechst 33253 staining (magnification, ×200). The arrows represent apoptotic cells. (B) Quantitative analysis of the number of apoptotic cells. Data are shown as mean ± S.D. n=6/group, **P<0.01 compared with PM2.5-stimulated group; ##P<0.01 compared with control group.
