Figure 4From: Low-solubility particles and a Trojan-horse type mechanism of toxicity: the case of cobalt oxide on human lung cellsFlow cytometry analysis of internalization of Co 3 O 4 particles by BEAS-2B cells. Scatter measurements by flow cytometry after 5 h incubation with cobalt oxide (200 μg.mL−1 Co), LB-3 latex beads (200 μg.mL−1 LB-3), or without cobalt (A). The results are illustrated by a dot plot representing FSC (forward scatter) versus SSC (side scatter). Flow cytometric histograms of cells exposed to Co3O4 (200 μg.mL−1 Co) for various incubation times (B). 10,000 events were counted for each sample. Data are representative of two independent experiments.Back to article page
