Одним из таких наполнителей может служить гидрогель на основе внеклеточного матрикса дермы, который содержит поверхностные лиганды, способные обеспечивать топографические и биологические сигналы для регенерации нервов.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: Провести оценку эффективности восстановления седалищного нерва крысы при использовании дермального гидрогеля в качестве наполнителя в коллагеновом кондуите в эксперименте in vivo.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы: В исследовании оценивалась эффективность коллагенового кондуита NeuraGen®, заполненного дермальным гидрогелем, в сравнении с аутографтом и полым коллагеновым кондуитом NeuraGen® при экспериментальном лечении дефекта седалищного нерва крысы более 1 см. Резекция седалищного нерва проводилась на крысах-самцах линии Wistar. На 30-, 60и 90-е сут. после имплантации рассчитывали седалищный функциональный индекс (Sciatic Functional Index, SFI) и соотношение обхвата голени оперированной лапы к интактной. На 90-е сут. эксперимента проводили электрофизиологические тесты и затем осуществляли эксплантацию образцов для гистологического окрашивания гематоксилин-эозином.</p></sec><sec><title>Результаты</title><p>Результаты: При оценке SFI-теста и электрофизиологических параметров были отмечены сопоставимые показатели функционального восстановления нерва у группы животных с аутографтом и группы с имплантацией коллагенового кондуита NeuraGen®, заполненного дермальным гидрогелем. В группе с имплантацией полого коллагенового кондуита NeuraGen® наблюдалась атрофия мышечной ткани, низкие показатели SFI-теста, скорости и продолжительности потенциала действия нервного импульса. Гистологический анализ образцов коллагенового кондуита, заполненного дермальным гидрогелем, продемонстрировал участки разрастания глии и отсутствие выраженной дегенерации нервных волокон на всем протяжении по сравнению с аутографтом, что свидетельствовало о регенерации нервных волокон.</p></sec><sec><title>Заключение</title><p>Заключение: При проведении оценки эффективности восстановления седалищного нерва крысы было выявлено, что коллагеновый кондуит NeuraGen®, заполненный дермальным гидрогелем, обеспечивает функционально-морфологическую интеграцию с нервом по сравнению с аутографтом. Полученные данные могут быть использованы для дальнейшей разработки и усовершенствования существующих нервных кондуитов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background: Current studies show that hollow conduits in combination with various synthetic and biological fillers significantly accelerate functional recovery of peripheral nerves. One of such fillers can be a hydrogel based on the extracellular matrix of the dermis, which contains surface ligands capable of providing topographic and biological signals for nerve regeneration.</p></sec><sec><title>Objective</title><p>Objective: To evaluate the effectiveness of rat sciatic nerve regeneration using a collagen conduit filled with dermal hydrogel in an in vivo experiment.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: We evaluated the effectiveness of the NeuraGen® collagen conduit filled with dermal hydrogel and compared it with that of an autograft and the NeuraGen® hollow collagen conduit in experimental treatment of rat sciatic nerve defects larger than 1 cm. Male Wistar rats underwent sciatic nerve resection. We calculated the Sciatic Functional Index (SFI) and ratio of the calf circumference in an operated limb to that in an intact limb on days 30, 60, and 90 after implantation. We performed electrophysiological tests and explanted samples for hematoxylin-eosin staining on day 90 of the experiment.</p></sec><sec><title>Results</title><p>Results: When assessing the SFI and electrophysiological parameters, the group of animals with autografts and the group with the NeuraGen® collagen conduits filled with dermal hydrogel demonstrated similar results. We observed muscle atrophy, low SFI scores, and low velocity and short duration of the action potential in the group with the hollow NeuraGen® collagen conduits. Histological analysis of explanted samples of the collagen conduits filled with dermal hydrogel demonstrated areas of glial proliferation and the absence of pronounced degeneration of nerve fibers throughout the implant compared with autografts, indicating functional regeneration of nerve fibers.</p></sec><sec><title>Conclusions</title><p>Conclusions: Evaluation of the effectiveness of rat sciatic nerve regeneration showed that the NeuraGen® collagen conduit filled with dermal hydrogel provides functional and morphological integration with the nerve compared with an autograft. Our findings can be used for further development and improvement of nerve conduits.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>коллагеновый кондуит</kwd><kwd>дермальный гидрогель</kwd><kwd>повреждение седалищного нерва</kwd><kwd>NeuraGen</kwd></kwd-group><kwd-group xml:lang="en"><kwd>collagen conduit</kwd><kwd>dermal hydrogel</kwd><kwd>sciatic nerve injury</kwd><kwd>NeuraGen®</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Кубанского научного фонда, ФГБОУ ВО КубГМУ Минздрава России в рамках научного проекта № МФИ-П-20.1/47.</funding-statement><funding-statement xml:lang="en">The study was funded by the Kuban Science Foundation and Kuban State Medical University under scientific project No. МФИ-П-20.1/47.</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">Griffin JW, Hogan MV, ChhabraAB, Deal DN.
