Stem cells, senescence, oxidative stress

... radicals in the cell, which causes DNA damage (double-stranded breaks). If the cell is stressed enough, it will enter senescence (the cellular dormancy associated with old age) prematurely. There are two papers you could skim over to see if you're interested: Torella D, Rota M, Nurzynska D, ...
