TiOparticles (A) were found inside all cell types, i.e. MDM, epithelial cells, and MDDC, as aggregates in vesicles (A, left panel), and as single particles or as small aggregates free in the cytoplasm (A, right panel). Silver enhanced gold particles (B) were found in all three cell types as single particles or as small aggregates only free in the cytoplasm and even in the nucleus (B, arrow). The circles mark the region where the element analysis was performed.
