Normal cells do not divide indefinitely due to a process termed cellular or replicative senescence. Cellular senescence contributes to aging and decline in tissue function. In considering a role for replicative senescence in the ageing process, we can first assume that it is only a contributory factor. Telomeres, replicative senescence and human ageing. Induction of replicative senescence by 5-azacytidine: fundamental cell fluid derived fibroblast-like cells and non-ageing NIH-3T3 cells with 5-azacytidine. Publication » Stem cell ageing, replicative senescence, and tumorigenesis. In addition to human fibroblasts, replicative senescence has been observed in a variety of cell types derived from many species (8,9). In culture, Ageing is the loss of efficient cellular function & response to environment, while Senescence is the loss of replicative capacity. Consequently, cellular senescence is sometimes termed cellular ageing or replicative senescence. Age-related decreases of the cellular replicative capacity can be reproduced by in vitro assays of cellular ageing. Cellular senescence is triggeredwhen telomeres are on average 4-6 kb Telomere contributes to aging ONLY IF replicative senescence contributes to aging. Ageing is intrinsically complex, being driven by multiple causal mechanisms. In culture before they enter a state of viable cell cycle arrest termed senescence. Keywords: Cellular senescence, Aging, MicroRNA, Non-coding RNA, Age- related Replicative senescence, miRNAs, and age-associated. Since then, replicative senescence has been considered as a cellular model of aging that may provide insight into organismal aging [3–5]. Cell senescence is the limited ability of primary human cells to divide when cultured in vitro. We have established an in vitro culture model of cellular aging in which We have analyzed the process of replicative senescence in CD8 T cells by using a.
