Abstract (original English)
The impact of culture conditions and interaction with activated peripheral blood mononuclear cells on the interleukin (IL) gene expression profile and proinflammatory IL-6 and IL-8 production by adipose-derived stromal cells (ASCs) was investigated. A microarray analysis revealed a wide range of IL genes either under standard (20%) or hypoxic (5%) O2 concentrations, some highly up-regulated at hypoxia. IL-6 and IL-8 production was inversely dependent on cell culture density. In early (first-third) passages, IL-6 and IL-8 concentration was higher at 20% O2 and in late (8th-12th) passages under 5% O2. Interaction between ASCs and mononuclear cells in indirect setting was accompanied with a significant decrease of IL-6 and did not result in the elevation of IL-8 concentration. Thereby, the production of proinflammatory interleukins (IL-6 and IL-8) may be affected by the ASC intrinsic features (density in culture, and duration of expansion), as well as by microenvironmental factors, such as hypoxia and the presence of blood-borne cells. These data are important for elucidating ASC paracrine activity regulation in vitro. They would also be on demand for optimisation of the cell therapy protocols, based on the application of ASC biologically active substances. SIGNIFICANCE PARAGRAPH: Ex vivo expansion is widely used for increasing the number of adipose-derived stromal cells (ASCs) an
