Senescent cells accumulate with age, a situation that appears more a result of the aging immune system failing to achieve timely clearance of newly senescent cells rather than a significant increase in the pace at which cells become senescent. Senescence occurs in response to cellular damage and stress, but also when somatic cells reach the...

A cell becomes senescent given sufficient stress, molecular damage, or on reaching the Hayflick limit on replication. A senescent cell ceases replication, grows in size, and…
