Figure 5. Liver mitochondrial structure. Electron micrographs of liver from wild-type mice (left panel), mtDNA mutator mice (middle panel) and mtDNA mutator mice treated with SkQ1 (right panel). Animals were 245 – 252 days old. Insertion in the middle panel, lower micrograph: intramitochondrial myelin-like structure at higher magnification. Similar findings were observed in 4-5 other mice of each group.
