Morphological changes induced by BJe in THP-1 cells. Cells were exposed to 0.5, 1 and 2.5 mg/mL of BJe up to 96 h or with 10 nM of PMA. In comparison with unexposed monocytes (CTRL), differentiated macrophage-like cells tend to adhere to the surface of the cultivation dishes, as indicated by yellow arrows. Cells were examined by light microscopy (400× magnification; scale bar 100 µm). Pictures are representative of three different experiments.
