Сравнить влияние системного и локального введения мезенхимальных стволовых клеток жировой ткани (МСК ЖТ) в дозе 1 × 106 клеток/кг на ноцицептивную чувствительность крыс и структурные изменения седалищного нерва и периневральных тканей травмированной конечности в экспериментальной модели периферической нейропатии (НП) седалищного нерва.Материалы и методы. У 26 крыс-самцов линии Wistar осуществили моделирование периферической нейропатии методом аксотомии седалищного нерва. На 7-е сутки экспериментальным животным провели системную либо локальную трансплантацию МСК ЖТ в дозе 1 × 106 клеток/кг. Проведена оценка ноцицептивных реакций на механический и термический стимулы в течение 90 суток после системной либо локальной трансплантации МСК ЖТ. Tакже проведен анализ гистоструктуры седалищного нерва и окружающих тканей.Результаты. Системное введение МСК ЖТ в дозе 1 × 106 клеток/кг крысам с аксотомией седалищного нерва приводило к увеличению порога ноцицептивной реакции (ПНР) на 17,1 % без влияния на латентный период ноцицептивной реакции (ЛПНР). Локальное введение МСК ЖТ в эквивалентной дозе способствовало полному восстановлению ПНР и ЛПНР к 21-м суткам исследования, а также снижению воспалительной реакции в мягких тканях прооперированной задней лапы подопытных животных.Заключение. Внутримышечное введение МСК ЖТ в область аксотомии седалищного нерва крыс значительно превышало по эффективности системное введение эквивалентной дозы клеточного трансплантата. Данный способ введения представляется более целесообразным для дальнейших исследований механизмов антиноцицептивных и репаративных эффектов МСК ЖТ.</p></abstract><trans-abstract xml:lang="en"><p>Objective. Compare the effectiveness of systemic and local administration of adipose-derived mesenchymal stem cells (ADMSC) at a dose of 1х106 cells/kg on nociceptive sensitivity to mechanical and thermal stimuli in rats and changes in histostructure of sciatic nerve and surrounded tissues of affected hind paw in experimental model of peripheral neuropathy of sciatic nerve.Materials and methods. 26 male Wistar rats were used to perform a model of peripheral neuropathy by axotomy of the sciatic nerve. On the 7th day, the experimental animals underwent systemic or local transplantation of ADMSC at a dose of 1x106 cells/kg. Nociceptive responses to mechanical and thermal stimuli were assessed for 90 days, and the histostructure of the sciatic nerve and surrounding tissues was analyzed after systemic and local transplantation of ADMSC.Results. Systemic administration of ADMSC at a dose of 1x106 cells/kg to rats with sciatic nerve axotomy increased the mechanical withdrawal threshold (MWT) by 17.1% and had no effect on the thermal withdrawal latency (TWL). Local administration of ADMSCs in an equivalent dose contributed to the full recovery of the MWT and TWL by the 21st day of the experiment, as well as suppressed the inflammatory reaction in the soft tissues of the operated hind paw of experimental animals.Conclusion. Intramuscular administration of ADMSC into the area of sciatic nerve axotomy of rats was significantly more effective than systemic administration of an equivalent dose of a cell transplant. This method of administration is more appropriate for further studies of the mechanisms of antinociceptive and reparative effects of ADMSCs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мезенхимальные стволовые клетки</kwd><kwd>нейропатическая боль</kwd><kwd>седалищный нерв</kwd><kwd>гипералгезия</kwd><kwd>анальгезия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mesenchymal stem cells</kwd><kwd>neuropathic pain</kwd><kwd>sciatic nerve</kwd><kwd>hyperalgesia</kwd><kwd>analgesia</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено в рамках задания «Оценка влияния обогащенной тромбоцитами плазмы, суспензии митохондрий и мезенхимальных стволовых клеток на ноцицептивную чувствительность, стимуляцию ангиогенеза и репаративные процессы в ишемизированной ткани при экспериментальной диабетической ангиопатии» ГПНИ «Трансляционная медицина», подпрограмма «Экспериментальная медицина» (№ госрегистрации 20210931).</funding-statement><funding-statement xml:lang="en">The study was performed within the framework of the project “Assessment of the influence of platelet-rich plasma, suspension of mitochondria and mesenchymal stem cells on nociceptive sensitivity, stimulation of angiogenesis and reparative processes in ischemic tissue in experimental diabetic angiopathy” of the State research program “Translational Medicine”, subprogram “Experimental Medicine” (registration number 20210931).</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">Scholz J, Finnerup NB, Attal N, et al.
