Figure 7. The effect of aminochrome on lipid droplets in U373MG cells. Normal amount of lipid droplets was observed in U373MG incubated with cell culture medium (A) or 75 µM aminochrome (B) for 24 h. U373MGsiGST6 cells incubated with cell culture medium (C) also presented normal amount of lipid droplets contrasting with a significant increase of lipid droplets observed in U373MGsiGST6 cells incubated with 75 µM aminochrome for 24 h (D and E). The lipid droplets are indicated with white arrows. Scale bars: (A–D) 2 µm; (E) 0.25 µm; nucleus (N).
