Cellular senescence is a process in which the cell cycle becomes permanently arrested, thereby inhibiting cell division, proliferation and growth. Various cellular stresses, such as DNA damage, telomere shortening and oxidative stress, can trigger cellular senescence. Physiologically, cellular senescence contributes to tissue development, repair and critical biological processes such as embryogenesis, whereas, pathologically, it plays a key role in diverse conditions, including age-related disease, some cancers, Alzheimer’s disease, and others.
Cellular senescence may be to blame for some diseases
