| Abstract: Stem cells, especially mesenchymal stem cells (MSCs)-based therapies have been greatly
attentioned in regenerative medicine through multi-lineage differentiation, self-renewal properties, etc.
Despite the above advantages of MSCs, the defined properties of these cells are strongly affected by aging.
Thus, the use of MSCs from older donors is lower than younger one, which limits clinical applications in
cell therapy. According to the theories of aging, it is determined that aging is most likely caused by telomere
shortening and telomere shortening is considered hallmarks of aging. Finding out the most mechanisms
of these changes will probably reveal novel therapeutic targets for prolonging human health and for
ameliorating age-associated phenotypes. This review focuses on prevalent knowledge about the mechanisms
of stem cell senescence by telomere shortening and the molecular mechanism details involved in it. |
