In 3D cultures, cells are under conditions that closely resemble those existing in healthy and disease-stricken human organs and tissues. Therefore, the development of a 3D model based on the Ea.hy926 endothelial cell line is an urgent need in molecular and cellular biology. Cell cultivation on an anti-adhesive substrate under static conditions was shown to lead to the formation of spheroids (3D cultures). Expression of ICAM-1 and VEGFR-2 and production of cytokines were screened in 2D and 3D cultures in the presence of TNF and VEGF. According to flow cytometry and confocal microscopy data, TNF significantly increased the expression of the cell adhesion molecule ICAM-1 in both 2D and 3D cultures but did not affect the expression level of VEGFR-2. Increased production of pro-inflammatory (IL-8, IL-6, IP-10) and anti-inflammatory (IL-10, TGF-β 1-3) factors was observed in spontaneous 3D cultures but not in 2D cultures, which was confirmed by flow cytometry and qPCR. TNF-induced secretion of IL-10, GM-CSF, and IL-6 was 11-, 4.7-, and 1.6-fold higher, respectively, in 3D cultures compared to 2D cultures. Thus, the use of a Ea.hy926 3D cell culture is a promising approach in studying the effects of anti- and pro-inflammatory agents on endothelial cells.</p></abstract><trans-abstract xml:lang="ru"><p>Клетки эндотелия играют ключевую роль в развитии воспаления и неоангиогенеза при онкологических и хронических воспалительных заболеваниях. Клетки в составе 3D-культур наиболее приближены к условиям, в которых они находятся в органах и тканях человека при различных патологиях. Поэтому создание модели 3D-культур на основе эндотелиальных клеток линии Ea.hy926 является актуальной задачей клеточной биологии. Впервые показано, что культивирование клеток в статичных условиях на антиадгезивной подложке приводит к образованию сфероидов (3D-культур). Изучена экспрессия ICAM-1 и VEGFR-2, а также продукция цитокинов клетками Ea.hy926, культивируемыми в 2D- и 3D-условиях в присутствии TNF и VEGF. Методами проточной цитометрии и конфокальной микроскопии показано, что TNF как в 2D-, так и в 3D-культурах значительно усиливает экспрессию молекулы клеточной адгезии ICAM-1, но не влияет на уровень VEGFR-2. В спонтанных 3D-культурах наблюдалась повышенная продукция как провоспалительных (IL-8, IL-6, IP-10), так и противовоспалительных (IL-10, TGF-β 1-3) факторов по сравнению с 2D-условиями, что показано как методом проточной цитометрии, так и кПЦР. Под действием TNF в 3D-культурах секреция IL-10, GM-CSF и IL-6 повышается в 11, 4.7 и 1.6 раза соответственно по сравнению с 2D-культурами. Таким образом, использование 3D-культур клеток Ea.hy926 представляется перспективным для изучения эффектов противо- и провоспалительных агентов на клетки эндотелия.</p></trans-abstract><kwd-group xml:lang="en"><kwd>2D and 3D cultures</kwd><kwd>αvβ3-integrin</kwd><kwd>vascular endothelial growth factor receptor 2</kwd><kwd>intercellular adhesion molecule</kwd><kwd>tumor necrosis factor</kwd><kwd>inflammation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>молекула межклеточной адгезии</kwd><kwd>2D- и 3D-культуры</kwd><kwd>рецептор фактора роста эндотелия сосудов-2</kwd><kwd>фактор некроза опухоли</kwd><kwd>эндотелиальные клетки</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by a grant from the Program of the Presidium of the Russian Academy of Sciences “Molecular and cellular biology,” a grant from the President of the Russian Federation for state support to the leading scientific schools of the Russian Federation NSh-8384.2016.4, and a grant from the UMNIK program of the Foundation for the Promotion of Small Forms of Enterprises in the Science and Technology Sphere.</funding-statement><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке гранта Программы Президиума РАН «Молекулярная и клеточная биология», гранта Президента Российской Федерации для государственной поддержки ведущих научных школ Российской Федерации НШ-8384.2016.4 и гранта по программе «УМНИК» Фонда содействия развитию малых форм предприятий в научно-технической сфере.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>[1] Astrakhantseva I.V., Efimov G.A., Drutskaya M.S., Kruglov A.A., Nedospasov S.A. // Biochemistry. 2014, V.79, №12, P.1308-1321</mixed-citation></ref><ref id="B2"><label>2.</label><mixed-citation>[2] Petrovskaya L.E., Shingarova L.N., Kryukova E.A., Boldyreva E.F., Yakimov S.A., Guryanova S.V., Novoseletsky V.N., Dolgikh D.A., Kirpichnikov M.P. // Biochemistry. 2012, V.77, №1, P.79-89</mixed-citation></ref><ref id="B3"><label>3.</label><mixed-citation>[3] Arjamaa O., Aaltonen V., Piippo N., Csont T., Petrovski G., Kaarniranta K., Kauppinen A. // Graefe’s Arch.
