Mitochondrial phenotypes in native and cultured smooth muscle cells. a A cultured single vascular smooth muscle cell showing the arrangement of mitochondria. The organelle is scattered through the cytoplasm and is arranged in various orientations. Mitochondria were labelled with MitoTracker Green. b Example mitochondria showing the diverse phenotypes that include small spheres, swollen spheres, straight rods, twisted rods, branched rods and loops. c A native smooth muscle cell showing the arrangement of mitochondria. The organelle is distributed throughout the cytoplasm and appears to be largely organised parallel to the long axis of the cell. Mitochondria were labelled with MitoTracker Green. d Example mitochondria showing the relatively uniform mitochondrial phenotype (when compared to the cultured cell) of spheres and straight rods. Scale bars = 10 μm.
