Senescence-associated ß-galactosidase staining over the lifespan differs in a short- and a long-lived fish species

Abstract excerpt

During the aging process, cells can enter cellular senescence, a state in which cells leave the cell cycle but remain viable. This mechanism is thought to protect tissues from propagation of damaged cells and the number of senescent cells has been shown to increase with age. The speed of aging determines the lifespan of a species and it varies significantly in different species. To assess the progress of cellular...
