Figure 4. Effect of blue light on mitochondrial shape. The figure shows electron micrographs of sections from untreated ARPE-19 cells (A, D), irradiated cells with an output at 0.3 mW/cm2 (B, E) and 1 mW/cm2 (C, F) for 72 h (Bar=1 μm). Irradiated cells showed mitochondria with unusually elongated profiles.
