High content of mitochondria in Rb–/– adipocytes. Wild-type and Rb–/– adipocytes were analyzed for mitochondrial abundance by MitoTracker Green staining and electron microscopy. (A) Representative area of live wild-type and Rb–/– adipocytes stained with MitoTracker Green. The same panel of cells was captured by both light and fluorescence microscopy. (B) Electron microscopic analysis of mitochondrial numbers in wild-type and Rb–/– adipocytes. Two representative cells of each genotype are shown.
