В настоящее время отсутствуют эффективные и безопасные препараты для лечения идиопатического мужского бесплодия. Эффективность нового препарата на основе секретома мезенхимных стромальных клеток (МСК) при бесплодии показана ранее на двух животных моделях: временный крипторхизм у крыс и химиотерапевтическое повреждение сперматогенеза доксорубицином у мышей.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ. изучение токсических свойств препарата на основе секретома мезенхимных стромальных клеток при локальном введении в яички и при внутримышечном введении препарата крысам.</p></sec><sec><title>МАТЕРИАЛЫ И МЕТОДЫ</title><p>МАТЕРИАЛЫ И МЕТОДЫ. Секретóм МСК представляет собой набор факторов, секретируемых МСК в среду для кондиционирования DMEM-LG. Для изучения токсичности при однократном применении препарат на основе секретома МСК вводили самцам крыс линии Wistar под белочную оболочку семенника в дозах, в 1,5 и 2,5 раза превышающих терапевтическую дозу (10 условных единиц (УЕ)): 15 УЕ/животное и 25 УЕ/животное соответственно; число животных в каждой группе n=15. Для изучения токсических свойств при многократном применении препарат вводили самцам крыс линии Wistar в мышцу бедра на 1, 6 и 12 сут исследования в дозах 15 и 25 УЕ, число животных в каждой группе n=10. Для оценки местной переносимости были проведены патологические и гистологические исследования семенников и мышечной ткани бедра в месте введения препарата. В качестве контроля во всех исследованиях использовали группу интактных крыс и группу крыс, которой аналогичным путем вводили среду DMEM без продуктов секреции МСК. Срок наблюдения составлял 14 сут, период отсроченного наблюдения — 42 сут.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. При однократном и многократном введении крысам препарата на основе секретома МСК не наблюдали изменений в общем состоянии животных. Однократное введение под белочную оболочку семенника оказало умеренное местнораздражающее действие, которое выражалось в патологическом изменении единичных семенных канальцев, а именно атрофии эпителия (у 70% животных через 14 сут, у 55% — в группе отсроченного наблюдения) и застое спермы (у 70% животных). Аналогичные изменения наблюдали в группе контроля с введением среды DMEM (до 80% животных). При многократном введении патологических изменений ткани не наблюдали. У животных, получавших изучаемый препарат в дозе 25 УЕ внутримышечно, после 3-кратного введения обнаружено обратимое повышение уровня активности щелочной фосфатазы, остальные биохимические показатели у крыс во всех группах были в норме.</p></sec><sec><title>ВЫВОДЫ</title><p>ВЫВОДЫ. Препарат на основе секретома МСК обладает приемлемым профилем безопасности при локальном и внутримышечном введении крысам, поскольку не вызывает необратимых патологических изменений в изученных органах и тканях.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>SCIENTIFIC RELEVANCE</title><p>SCIENTIFIC RELEVANCE. Currently, there are no effective and safe medicinal products for idiopathic male infertility. Previous studies in two animal models of infertility (short-term cryptorchidism in rats and doxorubicin-induced testicular injury in mice) have shown the effectiveness of an originator medicinal product based on the mesenchymal stromal cell (MSC) secretome.</p></sec><sec><title>AIM</title><p>AIM. The aim of the study was to evaluate the toxicity profile of the MSC secretome-based medicinal product in rats after local intratesticular or intramuscular administration.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS. The MSC secretome is a combination of factors secreted by MSCs in low-glucose Dulbecco’s modified Eagle’s medium (DMEM-LG) for MSC conditioning. In the single-dose toxicity study, the MSC secretome-based medicinal product was injected under the testicular tunica albuginea of male Wistar rats (15 per group) at doses of 15 and 25 relative units (RU) per animal, which are 1.5 and 2.5 times higher than the therapeutic dose (10 RU). In the repeat-dose toxicity study, male Wistar rats (10 per group) received intramuscular thigh injections of the medicinal product on days 1, 6, and 12 at doses of 15 and 25 RU per animal. The local tolerance study involved histopathological examination of the testes and thighs at the injection site. All studies included control groups of intact animals and animals similarly injected with blank DMEM-LG. The early follow-up period was 14 days, and the late follow-up period was 42 days.</p></sec><sec><title>RESULTS</title><p>RESULTS. The rats showed no changes in the general condition after single and repeated doses of the MSC secretome-based medicinal product. Single subtunical doses induced moderate irritation; its signs included pathological changes in individual seminiferous tubules: epithelial atrophy (70% of the animals on day 14; 55% at late follow-up) and sperm stasis (70% of the animals). Similar changes were observed in the blank DMEM-LG group (up to 80% of the animals). There were no pathological changes in the tissues after repeated injections. A transient increase in alkaline phosphatase activity was detected in animals after their third intramuscular injection at a dose of 25 RU; the other biochemical parameters were normal in all study groups.</p></sec><sec><title>CONCLUSIONS</title><p>CONCLUSIONS. The MSC secretome-based medicinal product has a favourable safety profile following both intratesticular and intramuscular administration, as it does not cause any permanent changes in the studied organs and tissues.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>мезенхимные стромальные клетки</kwd><kwd>секретóм мезенхимных стромальных клеток</kwd><kwd>сперматогенез</kwd><kwd>грызуны</kwd><kwd>безопасность</kwd><kwd>общая токсичность</kwd><kwd>субхроническая токсичность</kwd><kwd>местная токсичность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mesenchymal stromal cells</kwd><kwd>mesenchymal stromal cell secretome</kwd><kwd>spermatogenesis</kwd><kwd>rodents</kwd><kwd>safety</kwd><kwd>general toxicity</kwd><kwd>subchronic toxicity</kwd><kwd>local toxicity</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках государственного задания Медицинского научно-образовательного центра Московского государственного университета имени М.В.
