Однако он лишён необходимых физико-механических характеристик при создании материалов для нужд сердечно-сосудистой хирургии. Получение гибридного гидрогеля с взаимопроникающей сетью на основе фибрина и поливинилового спирта может улучшить свойства фибрина, в частности, повысить физико-механические характеристики и уменьшить склонность к усадке.</p><p>Цель – выполнить последовательную полимеризацию фибрина и поливинилового спирта для получения гибридного гидрогеля и изучить его свойства в сравнении с монокомпонентными гидрогелями.</p><sec><title>Материал и методы</title><p>Материал и методы. Из периферической крови пациентов методом этаноловой преципитации выделяли фибриноген, к нему добавляли поливиниловый спирт, растворенный в физиологическом растворе. Сначала инициировали полимеризацию фибрина, добавляя в раствор хлорид кальция. После следовал этап криоструктурирования поливинилового спирта циклами заморозки, разморозки и оттаивания. Таким образом, были приготовлены гибридные гидрогели на основе фибрина и поливинилового спирта и образцы из чистого фибрина и чистого поливинилового спирта. Изучали структуру гидрогелей, физико-механические свойства, усадку и биологическую активность. Статистическую обработку проводили в программе GraphPad Prism 6.</p></sec><sec><title>Результаты</title><p>Результаты. 3-D структура гибридного гидрогеля представлена сочетанием полигональных полостей поливинилового спирта, оплетенных сетью тонких фибриновых волокон. Распределение компонентов было равномерным в толще образцов, тогда как на поверхности преобладал поливиниловый спирт. Удлинение (247 (220,0; 293,2) %; р = 0,0005) и модуль Юнга (0,09 (0,11; 0,13) мПа; р = 0,0001) гибридного гидрогеля были статистически значимо выше относительно значений фибрина. Гибридный гидрогель не дал усадку, в отличие от фибрина, который усел в 11 раз. Количество адгезированных эндотелиальных клеток на матрицах из гибридного гидрогеля было в 8 раз выше, чем на поливиниловом спирте, но в 10 раз меньше, чем на фибрине. Пролиферативная активность клеток на поливиниловом спирте отсутствовала, на IPN-гидрогеле отмечено 13,6% пролиферирующих клеток, на фибрине 59,52%.</p></sec><sec><title>Заключение</title><p>Заключение. Способ последовательной полимеризации IPN-гидрогеля фибрина и поливинилового спирта дает равномерное распределение волокон в толще материала и позволяет получать гидрогели с улучшенными механическими свойствами, отсутствием склонности к усадке. Но перераспределение компонентов на поверхности гибридного гидрогеля в пользу поливинилового спирта с поддержанием относительно низкой адгезионности материала диктует необходимость проведения дальнейших экспериментов по созданию оптимальных условий для жизнедеятельности клеток.</p></sec></abstract><trans-abstract xml:lang="en"><p>Fibrin  displays  promising  characteristics  for tissue  engineering.  However,  it has suboptimal  physical  and mechanical properties when used as a material for cardiovascular applications. Obtaining an interpenetrating polymer network (IPN) hydrogel based on fibrin and polyvinyl alcohol (PVA) can improve the physical and mechanical characteristics and shrink behavior of fibrin.</p><sec><title>Aim</title><p>Aim: To perform sequential polymerization of fibrin and PVA to obtain IPN hydrogel and analyze its properties in comparison with monocomponent hydrogels.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. Fibrinogen was isolated from the peripheral blood of patients using ethanol precipitation, then polyvinyl alcohol dissolved in saline was added to it. First, fibrin polymerization was initiated by adding calcium chloride to the solution. Then, it was followed by polyvinyl alcohol undergoing freeze–thaw cycles. Thus, a hydrogel based on fibrin and PVA, samples from pure fibrin and pure polyvinyl alcohol were prepared. We studied the structure of hydrogels, their physical and mechanical properties, shrink behavior and biological activity. Statistical data processing was carried out using the GraphPad Prism 6 software.</p></sec><sec><title>Results</title><p>Results. 3D structure of the hydrogel is presented by polyvinyl alcohol polygonal cavities with a network of thin fibrin fibers. The distribution of components was equal in the inside of the samples, while polyvinyl alcohol prevails on the surface. Elongation (247 (220.0; 293.2)%; p = 0.0005) and Young’s modulus (0.09 (0.11; 0.13) mPa; p = 0.0001) of the hydrogel were statistically significantly higher compared to fibrin values. The hydrogel did not shrink, unlike fibrin that shrunk (11-fold decrease in volume). The number of adherent endothelial cells on the hydrogel matrices was 8 times higher than on polyvinyl alcohol, but 10 times lower than on fibrin. There was no proliferative activity of cells on polyvinyl alcohol, but 13.6% of proliferating cells were noted on the IPN hydrogel, and 59.52% on fibrin</p></sec><sec><title>Conclusion</title><p>Conclusion. Using sequential polymerization to obtain the IPN hydrogel based on fibrin and polyvinyl alcohol provides an equal distribution of fibers in the thickness of the material, making it possible to obtain hydrogels with improved mechanical properties and shrink behavior. However, the components on the surface of the IPN hydrogel need to be redistributed - more polyvinyl alcohol should be added still maintaining a relatively low adhesiveness of the material. Therefore further research is necessary to create the most optimal conditions for cell activity.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрин</kwd><kwd>поливиниловый спирт</kwd><kwd>биоматериалы</kwd><kwd>биосовместимость</kwd><kwd>эндотелиальные клетки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fibrin</kwd><kwd>polyvinyl alcohol</kwd><kwd>biomaterials</kwd><kwd>biocompatibilit</kwd><kwd>endothelial cells</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках фундаментальной темы Научно-исследовательского института комплексных проблем сердечно-сосудистых заболеваний № 0419-2022-0001 «Молекулярные, клеточные и биомеханические механизмы патогенеза сердечно-сосудистых заболеваний в разработке новых методов лечения заболеваний сердечно-сосудистой системы на основе персонифицированной фармакотерапии, внедрения малоинвазивных медицинских изделий, биоматериалов и тканеинженерных имплантатов».</funding-statement><funding-statement xml:lang="en">This research was funded by the Complex Program of Basic Research under the Siberian Branch of the Russian Academy of Sciences within the Basic Research Topic of Research Institute for Complex Issues of Cardiovascular Diseases No. 0419-2022-0001 “Molecular, cellular and biomechanical mechanisms of the pathogenesis of cardiovascular diseases in the development of new treatment methods based on personalized pharmacotherapy, minimally invasive medical devices, biomaterials and tissue-engineered implants”.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Chlupáč J., Filová E., Riedel T., Houska M., Brynda E., Remy-Zolghadri M. et al.
