| Popis: | Aging is characterized by a progressive accumulation of cellular damage, which leads to impaired function. Little is known whether substrates can influence cell aging. This is of utmost importance in the development of medical devices that are in contact with human tissue for long periods of time. To address this question, we have used an accelerated aging cell model derived from Hutchinson-Gilford Progeria Syndrome (HGPS) induced pluripotent stem cells (iPSCs). Our results show that HGPS-iPSC smooth muscle cells (SMCs) have an increased aging profile in substrates with specific micropatterns than in flat ones. This is characterized by an up-regulation in the expression of progerin, beta-galactosidase, annexin 3 and 5, and caspase 9. Signs of cell aging are also observed in SMCs without HGPS cultured in substrates with specific microtopographies. It is further showed that specific micropatterned substrates induce cell aging by triggering a DNA damage program likely by the disruption between cyto- and nucleoskeleton. |
