Проводили гистохимическое исследование кожи латеральной поверхности бедра мышей линии C57BL/6J, экспонированных в течение 21–24 сут на борту Международной космической станции, а также животных контрольных групп – виварийного, базального и наземного. Детекция тучных клеток с оценкой участия секретома в процессах фибриллогенеза коллагена проводилась после использования протоколов раздельного и комбинированного гистохимического окрашивания раствором Гимза и импрегнации серебра. Анализ микропрепаратов проводился с использованием аппаратнопрограммного комплекса на основе исследовательского микроскопа ZEISS Axio Imager.А2 (Carl Zeiss, Germany).</p></sec><sec><title>Результаты</title><p>Результаты. Условия невесомости приводили к активизации либерализации компонентов секретома ТК во внеклеточный матрикс (количество дегранулированных форм достоверно возрастало до 61.5±3.3% по сравнению с показателями контрольных групп), изменению гистотопографической локализации, уменьшению интрацитоплазматического содержания крупных гранул, снижению кооперации с клетками фибробластического дифферона и интенсивности фибриллогенеза, урежению солокализации с ретикулярными волокнами дермы кожи, а также к модификации внутрипопуляционного взаимодействия. Обсуждаются возможные молекулярно-клеточные причины изменения активности фибриллогенеза и полимеризации молекул тропоколлагена в надмолекулярные волокнистые структуры в соединительной ткани кожи на борту Международной космической станции.</p></sec><sec><title>Заключение</title><p>Заключение. Пребывание в невесомости вызывало возрастание секреторной активности тучных клеток кожи, моделировало процессы межклеточного сигналлинга с другими представителями специфического тканевого микроокружения и приводило к ослаблению фибриллогенеза коллагена.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of research was to study participation of skin mast cells of C57BL/6J mice in the mechanisms of fibrillogenesis under zero gravity conditions.</p><sec><title>Material and methods</title><p>Material and methods. A histochemical study of the skin from the lateral thigh of the C57BL/6J mice exposed aboard the International Space Station for 21–24 days, as well as animals of the control groups – vivarium, baseline and ground, – was performed. Mast cells were detected with an assessment of the secretome participation in collagen fibrillogenesis after protocols of separate and combined histochemical staining with Giemsa’s solution and silver impregnation. Microsections were analyzed using a hardware-software complex based on a ZEISS Axio Imager. A2 research microscope (Carl Zeiss, Germany).</p></sec><sec><title>Results</title><p>Results. Zero-gravity conditions led to a change in the activity of mast cells degranulation and histotopographic localization, a decrease in the content of large granules, a decrease in the cooperation with fibroblast/ fibrocyte and the intensity of fibrillogenesis, a decrease in co-localization with the reticular fibers of the extracellular matrix of the skin tissue, as well as a modification of the intrapopulation interaction. The article discusses possible molecular-cellular causes of changes in the activity of fibrillogenesis and polymerization of tropocollagen molecules into supramolecular fibrous structures in the skin connective tissue aboard the International Space Station.</p></sec><sec><title>Conclusion</title><p>Conclusion. Zero gravity conditions caused an increase in the secretory activity of mast cells in the skin, simulated the processes of intercellular signaling with other representatives of the specific tissue microenvironment, and resulted in the weakening of collagen fibrillogenesis.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кожа</kwd><kwd>ретикулин</kwd><kwd>тучные клетки</kwd><kwd>мыши инбредные С57BL</kwd><kwd>невесомость</kwd><kwd>коллаген</kwd><kwd>соединительная ткань</kwd></kwd-group><kwd-group xml:lang="en"><kwd>skin</kwd><kwd>reticulin</kwd><kwd>mast cells</kwd><kwd>mice</kwd><kwd>inbred C57BL</kwd><kwd>weightlessness</kwd><kwd>collagen</kwd><kwd>connective tissue</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">Атякшин Д.А.
