Cellular senescence is an irreversible cell cycle arrest caused by various internal or external stimuli [1,2]. Senescence phenotype was first identified by Hayflick in normal human fibroblasts [3]. Senescence is caused due to exhaustion of cells by continuous replication (replicative senescence) or it can be induced (induced senescence or premature senescence) by various agents including reactive oxygen species, tumor suppressors, oncogenes, radiations etc. Senescent cells are characterized by high accumulation of β-galactosidase, p16INK4A, p21Waf1, flattened cells morphology, reduced cells proliferation and also the release of senescence associated secretory phenotypes (SASPs), which comprise proinflammatory cytokines and chemokines, extracellular matrix proteins, growth factors, and exosome-like small extracellular vesicles [4-7].
