Figure 5

Confocal images of A549 cells exposed to Si-85-FD particles in the absence of serum. Maximum intensity projection (b) and orthogonal views (xy, xz, and yz) of one cell within that image section ((a), (c), and (d)). Intersecting planes pass the middle of the image (cross hair). SNPs (magenta), membrane (cyan), and nuclear lamina (yellow).
