cell population phenotype abnormal phenotype stationary phase viability unaffected by tschimganine chronological lifespan unaffected by tschimganine Although each cell has a replicative lifespan in that it divides a certain number of times and then dies, replicative lifespan is often measured at the population level, where it is defined by the number of generations at which 50% of the starting cells are dead. A cell population phenotype in which the proportion of cells in the population remains viable after entering stationary phase does not change in the presence of tschimganine. Normally, wild-type cell populations survive longer in the presence of tschimganine than in its absence. midori loss of chronological lifespan extension by tschimganine stationary phase viability unaffected by TMN 2018-11-06T14:54:22Z loss of stationary phase viability extension in presence of tschimganine FYPO:0006736
