Representative micrographs of RP-cells incubated for 6 (A-D) or 16 (E) h, in the absence or presence of 2.5 µM arsenite. After treatments, the cultures were processed for the assessment of the fluorescence responses detected with Fluo 4 (A), Rhod 2 (B), DHR (C), MitoSOX red (D), as well as the cytochrome c immunofluorescence (E). Scale bars represent 20 µm.
