В научной литературе явно недостаточно данных о взаимодействии коллагеновых материалов с живым организмом и о влиянии на этот процесс мультипотентных стромальных клеток (МСК). Имеются противоречия о деградации коллагена и развитии реакций инородного тела. Однако без учета таких результатов невозможно оценивать сроки полного лизиса подобных материалов, разрабатывать эффективные методы профилактики и лечения развивающихся осложнений. Цель. Изучить особенности деградации материала на основе коллагена при его имплантации с адсорбированными аутологичными мезенхимальными МСК костномозгового происхождения (АММСККП) в эксперименте. Материалы и методы. Методом световой микроскопии изучали в разные сроки состояние тканей вокруг имплантированной коллагеновой мембраны с адсорбированными АММСККП. Результаты. Численность сосудов и клеточных элементов в имплантированной без АММСККП коллагенового материала нарастает до 3 недели и остается на этом уровне до окончания наблюдения. Отличительными особенностями применения коллагеновой мембраны с адсорбированными АММСККП являются усиление васкуляризации и клеточной инфильтрации материала в первые 2 недели после операции. Такой эффект в дальнейшем приводит к более быстрой деградации всего имплантированного коллагена, в том числе и более плотных его участков, но не предотвращает образования многоядерных макрофагов со слившейся цитоплазмой. Заключение. В результате более выраженной васкуляризации и клеточной инфильтрации, причиной которых являются адсорбированные на поверхности коллагенового материала АММСККП, к 4 неделе весь имплантат разрушается и абсорбируется, а на его месте формируется плотная волокнистая соединительная ткань. Для внедрения в организм следует выбирать наиболее однородные коллагеновые материалы без отличающихся по плотности участков, так как медленно деградирующие фрагменты могут явиться причиной развития гранулематозного воспаления и неудачи самой процедуры имплантации.</p></abstract><trans-abstract xml:lang="en"><p>Background. The scientific literature contents clearly not enough data at interaction of collagen materials with a living organism and about influence of multipotent stromal cells (MSC) on this process. There are controversies about the collagen degradation and the development of foreign body reactions. However, without account these results, it is impossible to estimate the timeframes for complete lysis of such materials, to progress effective methods for the prevention and treatment of developing complications. Objective. To study the features of the collagen-based material degradation after implantation with adsorbed autologous mesenchymal MSC of bone marrow origin (AMMSCBMO) in the experiment. Design and methods. In different times the condition of tissues around the implanted collagen membrane with adsorbed AMMSCBMO was studied by method of light microscopy. Results. The number of vessels and cellular elements in the collagen material implanted without AMMSCBMO increases to 3 weeks and remains at this level until the end of the observation. A distinctive features of the use of collagen membrane with adsorbed AMMSCBMO are increased vascularization and cellular infiltration of the material in the first 2 weeks after surgery. This effect further leads to a more rapid degradation of all implanted collagen, including its more dense parts, but does not prevent the formation of multinuclear macrophages with fused cytoplasm. Conclusion. As a result of more significant vascularization and cellular infiltration caused by AMMSCBMO adsorbed on the surface of the collagen material, to the 4th week the entire implant is full destroyed and absorbed, and dense fibrous connective tissue is formed in its place. For the implantation into the body, one should choose the most homogeneous collagen materials, without areas of different density, as slowly degrading fragments can cause the development of granulomatous inflammation and the failure of the implantation procedure.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мультипотентные мезенхимальные стромальные клетки</kwd><kwd>коллагеновый имплантат</kwd><kwd>воспаление</kwd><kwd>нейтрофилы</kwd><kwd>лимфоциты</kwd><kwd>макрофаги</kwd><kwd>эритроциты</kwd><kwd>гранулемы инородного тела</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multipotent mesenchymal stromal cells</kwd><kwd>collagen implant</kwd><kwd>inflammation</kwd><kwd>neutrophils</kwd><kwd>lymphocytes</kwd><kwd>macrophages</kwd><kwd>erythrocytes</kwd><kwd>foreign body reaction</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">Dunn MG, Avasarala PN, Zawadsky JP.
