Figure 6

PM10-induced overexpression of early endosomes in THP-1-derived macrophages. The cells were treated with summer Milan PM10 at the concentration of 2.5 μg/cm2 for 30 min and then stained for the early endosome antigen EEA1 (green). Nuclei are stained with DAPI (blue): representative images.
