title: Flow-cytometric analysis of mitochondria-associated fluorescence in young and old human fibroblasts.
abstract: Rhodamine 123 fluorescence in populations of young and old human fibroblasts was analysed and quantified with a fluorescence-activated cell sorter (FACS). Old fibroblasts exhibited a higher mean relative fluorescence than young fibroblasts. Moreover, two distinct subpopulations were evident in the fluorescence distributions of old cells--but not in those of young cells.
