Long-Term Quiescent Fibroblast Cells Transit into Senescence
Cellular senescence is described to be a consequence of telomere erosion during the replicative life span of primary human cells. Quiescence should therefore not contribute to cellular aging but rather extend lifespan. Here we tested this hypothesis and demonstrate that cultured long-term quiescent human fibroblasts transit into senescence due to similar cellular mechanisms with similar dynamic...
متن کاملResponse of a primary human fibroblast cell line to H2O2: senescence-like growth arrest or apoptosis?
Hydrogen peroxide has been shown to induce either apoptosis or features of senescence in different cultured cell lines. We now show that both processes can be induced in the same culture of primary human diploid fibroblasts and that the outcome of apoptosis or the senescence-like phenotype is determined by the H2O2 concentrations. At 50 and 100 microM, H2O2 predominantly induced the senescence-...
متن کاملChitosan Treatment Delays the Induction of Senescence in Human Foreskin Fibroblast Strains
Fibroblasts have been extensively used as a model to study cellular senescence. The purpose of this study was to investigate whether the human foreskin fibroblast aging process could be regulated by using the biomaterial chitosan. Fibroblasts cultured on commercial tissue culture polystyrene (TCPS) entered senescence after 55-60 population doublings (PDs), and were accompanied by larger cell sh...
متن کاملElevated miR-34c-5p Mediates Dermal Fibroblast Senescence by Ultraviolet Irradiation
Previous studies showed that several miRNAs can regulate pathways involved in UVB-induced premature senescence and response to ultraviolet irradiation. It has also been reported that miR-34c-5p may be involved in senescence-related mechanisms. We propose that miR-34c-5p may play a crucial role in senescence of normal human primary dermal fibroblasts. Here, we explored the roles of miR-34c-5p in...
متن کاملUse of the fibroblast model in the study of cellular senescence.
In this chapter, we present standard procedures for the culture of human cells that exhibit a finite proliferative capacity (replicative life-span). The use of a cell culture model has the advantage of providing a controlled environment to study a wide variety of cellular phenomena. It also has the inherent limitation of isolating cells from the regulatory elements that might be provided by oth...
