The use of alginate for transplanting biomedical cellular products to humans imposes high requirements on the sterility of the final product. To select the optimal protocol for cell encapsulation for further in vitro use or transplantation of cells enclosed in an alginate gel, it is necessary to study how sterilization processes affect such characteristics of the obtained gel as the ability to maintain cell viability and proliferation.</p><p><bold>The purpose of the study</bold> was to compare the effect of ultraviolet radiation and autoclaving on the biological properties of alginate gel.</p><p><bold>Materials and methods.</bold> MOLT-4 culture cells were encapsulated in 1, 2 and 4 % alginate beads at a concentration of 0.75 × 10<sup>6</sup> cells/ml. On the eighth day of cultivation, we measured the size of the colonies and determined the viability of the cells in an automatic cell counter.</p><p><bold>Results.</bold> The colony area for all variants of the concentration of alginate gel was significantly higher for a gel sterilized by UV treatment compared with autoclaving. The difference between the colony sizes for the two methods of alginate sterilization was significant at the accepted level of significance for all variants of gel concentrations (α = 0.05, df = 198, t = 1.972). Moreover, the number of viable cells after dissolution of alginate did not significantly differ between the experimental variants.</p><p><bold>Conclusion.</bold> Thus, autoclaving sterilization leads to proliferation retardation of encapsulated cells and cannot be recommended for use in protocols for the preparation of alginate capsules with encapsulated cells for in vitro and in vivo cultivation.</p></abstract><trans-abstract xml:lang="ru"><p/><p xml:lang="RU-RU"><bold>Введение</bold>. Инкапсуляция в альгинатный гель широко применяется в биомедицинских исследованиях для защиты клеток от механического воздействия и контакта с иммунной системой реципиента. Применение альгината для пересадки биомедицинских клеточных продуктов человеку налагает высокие требования к стерильности конечного продукта. С целью подбора оптимального протокола инкапсуляции клеток для дальнейшего применения in vitro или трансплантации заключенных в альгинатный гель клеток необходимо изучить, как процессы стерилизации влияют на такие характеристики получаемого геля, как способность к поддержанию жизнеспособности и клеточной пролиферации.  </p><p/><p xml:lang="RU-RU"><bold>Цель исследования</bold> – сравнительное изучение влияния ультрафиолетового излучения и автоклавирования на биологические свойства альгинатного геля.  </p><p/><p xml:lang="RU-RU"><bold>Материалы и методы.</bold> Клетки культуры MOLT-4 были заключены в бусины из 1, 2 и 4 % альгината в концентрации 0,75 × 10<sup>6</sup> кл/мл. На 8-е сутки культивирования проводилось измерение размера колоний и определение жизнеспособности клеток в автоматическом клеточном счетчике.  </p><p/><p xml:lang="RU-RU"><bold>Результаты. </bold>Площадь колоний для всех вариантов концентрации альгинатного геля оказалась достоверно выше для геля, стерилизованного обработкой ультрафиолетовыми лучами, по сравнению с автоклавированием. Разница в размерах колоний для 2 способов стерилизации альгината оказалась достоверной при принятом уровне значимости для всех вариантов концентраций геля (α = 0,05, df = 198, t = 1,972). При этом в вариантах опыта существенных отличий в количестве жизнеспособных клеток после растворения альгината не отмечено.  </p><p/><p xml:lang="RU-RU"><bold>Заключение. </bold>Cтерилизация автоклавированием приводит к подавлению пролиферации заключенных в него клеток и не может быть рекомендована для применения в протоколах подготовки альгинатных капсул с заключенными в них клетками для культивирования in vitro и in vivo. </p></trans-abstract><kwd-group xml:lang="en"><kwd>AUTOCLAVING</kwd><kwd>ULTRAVIOLET GERMICIDAL IRRADIATION</kwd><kwd>ALGINATE</kwd><kwd>ENCAPSULATION</kwd><kwd>MOLT-4</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>АВТОКЛАВИРОВАНИЕ</kwd><kwd>УЛЬТРАФИОЛЕТОВОЕ ИЗЛУЧЕНИЕ</kwd><kwd>АЛЬГИНАТ</kwd><kwd>ИНКАПСУЛЯЦИЯ</kwd><kwd>MOLT-4</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
