Цель Изучить в эксперименте с эндотелиальными клетками in vitro активность ростовых факторов и хемоаттрактантных молекул, инкорпорированных в состав полимерных матриксов на основе полигидроксибутирата/валерата и поликапролактона. Материалы и методы Нетканые матриксы из полигидроксибутирата/валерата и поликапролактона (PHBV/PCL) с изолированным или сочетанным введением в структуру сосудистого эндотелиального фактора роста VEGF, основного фактора роста фибробластов bFGF и хемоаттрактантной молекулы SDF-1a были изготовлены методом двухфазного электроспиннинга. С использованием культуры эндотелиальных клеток линии EA.hy 926 изучены адгезия, жизнеспособность и пролиферация клеток, культивируемых на поверхности матриксов, а также васкулогенез, секреторная активность и клеточный индекс клеток в ответ на диффузию в среду культивирования инкорпорированных в матриксы веществ. Результаты При анализе комплекса показателей доказана сохранность активности VEGF, bFGF и SDF-1a, инкорпорированных в состав матриксов PHBV/PCL, а также преимущество матриксов, содержащих комплекс ростовых факторов и хемоаттрактантных молекул (GFmix), в плане сбалансированности своего воздействия на адгезию, пролиферацию, жизнеспособность эндотелиальных клеток и активацию васкулогенеза. Диффузия из матриксов комплекса GFmix в культуральную среду стимулировала секрецию эндотелиоцитамить IL-10, и VE-кадгерина, что демонстрирует противовоспалительную активность и хороший клеточный контакт. Низкий уровень секретируемого клетками EA.hy 926 VEGF-A в лунках с матриксами, содержащими VEGF и GFmix, мог отражать феномен обратной связи, когда синтез вещества тормозится на фоне его достаточного присутствия в окружающей среде. Заключение Ростовые факторы и хемоаттрактантные молекулы, вводимые в состав нетканых полимерных матриксов методом электроспиннинга, сохраняют свою биологическую активность. Сочетание VEGF, bFGF и SDF-1a в составе одного матрикса синхронизирует эффекты клеточного отклика в отличие от изолированного введения данных веществ в состав матриксов.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>Background We fabricated biodegradable, bioactive scaffolds to guide the differentiation of endothelial progenitor cells. Aim To study in vitro activity of the bioactive factors incorporated into the poly (3-hydroxubutyrate-co-3-hydroxyvalerate)/poly(ε-caprolactone) (PHBV/PCL) scaffolds. Methods Nonwoven scaffolds were blended of PHBV and PCL utilizing either separate or combined incorporation of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and stromal cell-derived factor-1α (SDF-1α) by emulsion electrospinning. We further studied adhesion, viability, and proliferation of EA.hy 926 endothelial cells cultured on these scaffolds and evaluated vasculogenesis, cell index, and secretory profile in response to the addition of abovementioned bioactive factors. Results We showed that VEGF, bFGF, and SDF-1α retain their bioactivity upon the incorporation into the PHBV/PCL scaffolds. Scaffolds with all three bioactive factors incorporated demonstrated superior performance in comparison with those containing any of these factors alone. Diffusion of the bioactive factors into the culture medium stimulated the secretion of interleukin-10, and VE-cadherin by endothelial cells that indicated anti-inflammatory response and tight intercellular junctions. We also detected the low level of secreted VEGF-A from the scaffolds with VEGF suggestive of its physiological regulation. Conclusion Bioactive factors retain their bioactivity upon the incorporation into the PHBV/ PCL scaffolds. Combination of VEGF, bFGF, and SDF-1a improves cellular response compared to the incorporation of any of these factors alone.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эндотелиальные клетки</kwd><kwd>электроспиннинг</kwd><kwd>биодеградируемые полимеры</kwd><kwd>ростовые факторы</kwd><kwd>хемоаттрактантные молекулы</kwd><kwd>биологическая активность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>endothelial cells</kwd><kwd>electrospinning</kwd><kwd>biodegradable polymers</kwd><kwd>growth factors</kwd><kwd>chemoattractants</kwd><kwd>bioactivity</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена при поддержке комплексной программы фундаментальных научных исследований СО РАН в рамках фундаментальной темы НИИ КПССЗ № 0546-2015-0011 «Патогенетическое обоснование разработки имплантатов для сердечно-сосудистой хирургии на основе биосовместимых материалов, с реализацией пациент-ориентированного подхода с использованием математического моделирования, тканевой инженерии и геномных предикторов».</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">Palumbo V.D., Bruno A., Tomasello G., Damiano G., Lo Monte A.I.
