Control of mosaic cytochrome c distribution by Drp1 and mitochondrial Drp1 receptors. (A–E) WT (A), Mff^−/− (B), MiD49^−/− (C), MiD51^−/− (D), and Drp1^−/− (E) MEFs were treated with DMSO (control; left panels in A–E) or Acn (right panels in A–E) for 6 h. Typical examples of cells immunostained to detect cytochrome c (green) and Tom20 (red) are shown. Scale bars represent 20 µm (2 µm in detail images).
