ONLINE COVER Revealing Mitochondria. Shown are human skin cells in which mitochondria are fused and extend throughout the cytoplasm. Cells are stained with TMRE; the red color indicates maximally polarized mitochondria. In this issue, Pouli et al. report that skin cancer cells can be detected in vivo by visualizing dynamic changes in the structure and function of mitochondria, as revealed by the endogenous fluorescence of the metabolic cofactor NADH.
