Scanning ion-conductance microscopy was shown as more relevant method because it didn’t cause mechanical damage of cell, and made possible scanning on the membranes, when endothelial cells were surrounded by nutrient medium. The method allowed not only to analyze changes in the cells morphology, but also to identify extracellular (microfilaments) and intracellular (nucleolus) structures. The rigidity mapping showed that the rigidity of the endotheliocyte membrane varied from 357 to 796 Pa. After 240 min from the beginning of the observation, the formation of endothelial cells apoptotic bodies has begun, and the rigidity of the cell gradually increased, while rigidity of the apoptotic bodies decreased.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324989488">Разработана и апробирована двухсекционная аналитическая система для исследования культуры эндотелиальных клеток EA.hy926 в режиме реального времени с высоким разрешением. Показано, что релевантные результаты дает метод сканирующей ион-проводящей микроскопии, поскольку он обеспечивает отсутствие механических воздействий на клетки, и с его помощью возможно сканирование на мембранах, обеспечивающих окружение эндотелиальных клеток питательной средой. Метод дал возможность визуализировать не только изменения поверхности клеток в процессе длительного сканирования, но и детектировать внеклеточные (микрофиламенты) и внутриклеточные (ядрышко) структуры. Построение карт ригидности позволило определить, что значение жесткости мембран эндотелиоцитов находится в диапазоне от 357 до 796 Па. Через 240 мин от начала наблюдения начиналось формирование апоптозных тел эндотелиальными клетками, при этом ригидность самих клеток постепенно нарастала, а апоптозных тел – уменьшалась.</p></trans-abstract><kwd-group xml:lang="en"><kwd>endotheliocytes</kwd><kwd>apoptosis</kwd><kwd>membrane rigidity</kwd><kwd>cell morphology</kwd><kwd>microstructures</kwd><kwd>two-section analytical chamber</kwd><kwd>scanning ion-conductance microscopy</kwd><kwd>atomic force microscopy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эндотелиоциты</kwd><kwd>апоптоз</kwd><kwd>ригидность мембраны</kwd><kwd>морфология клетки</kwd><kwd>микроструктуры</kwd><kwd>двухсекционная аналитическая камера</kwd><kwd>сканирующая ион-проводящая микроскопия</kwd><kwd>атомно-силовая микроскопия</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают искреннюю благодарность С.А.
