Fig. 1From: Case report: a novel frameshift mutation in the mitochondrial cytochrome c oxidase II gene causing mitochondrial disorderHistology of vastus lateralis muscle from the patient harboring the m.8156delG mutation. a Hematoxylin and eosin stainings show ragged red fibers. Bar = 50 μm (b) SDH-COX staining shows that COX-deficient fibers encompass more than half of the fibers. Bar = 50 μm (c) NADH staining shows mitochondrial proliferation. Bar = 100 μmBack to article page
