Telomeres shorten with each cell division eventually leading to replicative senescence, a process thought to be associated with age-related decline in immune function.
However, MSC have a limited lifespan in vitro, exhibiting a progressive reduction in their capacity for self-renewal that usually ends in the irreversible arrest of cell division or replicative senescence [29, 30].
Cellular senescence resulting from repeated cellular replication is called "replicative senescence" [13, 14].
Unlike cells with limited number of divisions, immortal cells do not undergo replicative senescence. However, it was shown that they are prone to stress-induced senescence [71, 72].
This phenomenon, the "Hayflick limit" [43], also known as replicative senescence, restricts the life span in vitro of all primary mammalian somatic cells.
However, as MSCs are expanded, they undergo replicative senescence [15-17] and demonstrate morphological abnormalities, enlargement [18, 19], more podia and actin stress fibers [18, 20], less expression of specific surface markers, and decreased proliferation and differentiation [21-28].
Replicative senescence was used as an in vitro surrogate for aging [15].
Several factors lead to senescence, and one of them is the cellular division, with telomere shortening, called replicative senescence [23, 24].
Epigenetic modifications leading to chronic inflammation have been described in ECs and immune cells of diabetes patients also in the absence of replicative senescence biomarkers [23, 57, 58].
However, MSCs undergo replicative senescence, limiting the number of divisions [39-41].
The cell senescence has indicated the irreversible G1 growth arrest of normal primary cells, which occurs after the cells have accumulated time-dependent damage, during extensive culture passages ("replicative senescence").
Primary cultured cells undergo replicative senescence, which is characterized by telomere shortening, genomic damage, epigenomic damage, and activation of tumor suppressors [1].
