From: Mitochondrial mosaics in the liver of 3 infants with mtDNA defects
Liver, patient 2, cytochrome oxidase stain. 7a: Different levels of mitochondrial staining in adjacent hepatocytes, cryostat section. Nuclei slightly counterstained with methylgreen reveal cells without staining (arrow). 7b: Higher magnification: COX-positive parenchymal cells alternate with unstained ones. Large dark structures are erythrocytes (arrow). Nuclei slightly counterstained with methylgreen, cryostat section.
