Unlikeembryonic stem cells adult stem cells are subject of aging processes and theconcomitant decline in their function. Age-related changes in MSCs have to bewell understood in order to develop clinical techniques and therapeutics basedon these cells. In&amp;nbsp; this work we havestudied the effect of aging on adhesive behaviour of bone marrow-derived MSCand MG- 63 osteoblastic cells onto three extracellular matrix proteins:fibronectin (FN), vitronectin (VN) and collagen&amp;nbsp;I (Coll I). The results revealed substantial differences in adhesivebehaviour of both cell types during 21 days in culture. Bone-marrow derivedMSCs decreased significantly their adhesive affinity to all studied proteinsafter 7th day in culture with further incubation. In contrast, MG-63 cells,demonstrated a stable cell adhesive phenotype with high affinity to FN and CollI and low affinity to vitronectin over the whole culture period. These datasuggest that adhesive behaviour of MSCs to matrix proteins is affected by agingprocesses unlike MG-63 cells and the age-related changes have to be consideredwhen expanding adult stem cells for clinical applications.</p></abstract>
