title: Cellular aging and senescence.
abstract: Differentiated eukaryotic cells have only a finite capacity for cell division. This limitation is thought to be a cellular manifestation of organismal aging, and a restraint to tumor progression. The molecular basis for cellular senescence is not known, but a molecular framework for understanding this phenomenon has recently been established.
