Установлено, что культивирование МСК ЖТ в присутствии 100 нМ – 100 мкМ кверцетина увеличивает активность системы антиоксидантной защиты и устойчивость клеток к окислительному стрессу, снижает внутриклеточное содержание АФК (перекись водорода) и ингибирует дифференцировку клеток в адипогенном направлении. В концентрациях 10–100 нМ полифенол оказывает стимулирующее влияние на пролиферативную активность МСК ЖТ и не влияет на иммунофенотип клеток, при концентрациях 10–100 мкМ наблюдается снижение пролиферативной активности и изменение экспрессии маркеров мультипотентных МСК CD29, CD44 и CD90.</p></abstract><trans-abstract xml:lang="en"><p>The resistance to the oxidative stress, the proliferative activity, the immunophenotype stability, and the ability to differentiate in the adipogenic direction of MSCs from adipose tissue of rats after the incubation of cells in the presence of quercetin has been investigated. The cultivation of MSCs in the presence of 100 nM – 100 mM quercetin enhances the antioxidant defense system activity and the resistance of cells to the oxidative stress, decreases the intracellular ROS content (hydrogen peroxide), and inhibits the adipogenic differentiation of cells. At concentrations of 10–100 nM, polyphenol has a stimulating effect on the proliferative activity of MSCs and does not affect the immunophenotype of cells. At concentrations of 10–100 mM, quercetin decreases the proliferative activity of the cells and changes the expression of markers of multipotent MSCs CD29, CD44, and CD90.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Konno M., Hamabe A., Hasegawa S. et al. // Dev.
