Оценить выраженность ангиогенеза в месте имплантации матриц из поликапролактона (PCL), содержащих молекулы VEGF, в эксперименте in vivo.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Матрицы изготавливали из PCL методом электроспиннинга. Инкорпорирование молекул VEGF в PCL матрицы осуществляли с помощью двухфазного электроспиннинга. Поверхностную структуру всех матриц изучали методом сканирующей электронной микроскопии. Определение динамики выхода ростового фактора из полимерных волокон проводили иммуноферментным анализом. Для оценки биологических свойств PCL и PCL+VEGF матриц их имплантировали внутрибрюшинно крысам популяции Wistar (n=60) сроком на 2, 3 и 4 месяца с последующим проведением гистологических и гистохимических исследований.</p></sec><sec><title>Результаты</title><p>Результаты. Исследование показало, что структура PCL матриц значительно меняется после введения в их состав VEGF. Кроме того, был продемонстрирован длительный контролируемый выход молекул ростового фактора из матриц, а также сохранение их биологической активности, о чем свидетельствовало увеличение количества капилляров на матрицах с VEGF по сравнению с контролем после имплантации мелким лабораторным животным.</p></sec><sec><title>Заключение</title><p>Заключение. В работе было показано, что матрицы из поликапролактона с VEGF обладают более выраженным проангиогенным эффектом, чем матрицы без ростового фактора. Это делает возможным их применение в тканевой инженерии in vivo.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose. To evaluate the local angiogenesis stimulation by polycaprolactone (PCL) scaffolds with VEGF in vivo.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. PCL scaffolds were fabricated using electrospinning method. For the encapsulation of VEGF into PCL scaffold a two phase electrospinning was used. The scaffolds structure was examined by scanning electron microscopy. Growth factor release dynamic was assessed by ELISA. For evaluation of biological properties, the PCL and PCL+VEGF scaffolds were implanted in Wistar rat abdominal wall (n=60) for 2, 3 and 4 monthsT. he explanted samples were examined by histological and immunoishtochemical analyses.</p></sec><sec><title>Results</title><p>Results. The study showed that PCL fiber diameters in the scaffolds have changed after VEGF encapsulation. Moreover, long-term controlled release of growth factor was demonstrated. In addition, we have also shown the preservation of PCL+VEGF scaffolds biological activity; this was evidenced by increase of the number of capillaries on scaffolds with VEGF compared to control samples after implantation in rats.</p></sec><sec><title>Conclusion</title><p>Conclusion. This study showed that the PCL scaffold with VEGF has pro-angiogenic potential in comparison with pure scaffolds and can potentially be used for the tissue engineering in vivo.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>поликапролактон</kwd><kwd>сосудистый эндотелиальный фактор роста</kwd><kwd>электроспиннинг</kwd><kwd>тканевая инженерия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polycaprolactone</kwd><kwd>vascular endothelial growth factor</kwd><kwd>electrospinning</kwd><kwd>tissue engineering</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Anderson J.
