Замещение дефектов кости при помощи аутологичной кости всегда было «золотым стандартом», однако по ряду причин ее использование не всегда возможно. В качестве альтернативы были разработаны материалы биологического и небиологического происхождения с их предварительной обработкой. Новым направлением таких материалов являются тканеинженерные конструкции, способные полностью имитировать аутологичную кость в необходимом объеме.</p></sec><sec><title>Цель</title><p>Цель. Изучить in vivo возможность использования депротеинизированной губчатой костной ткани человека в качестве матрицы для создания тканеинженерных конструкций.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование проведено на 24 кроликах линии NZW, поскольку данная линия имеет полностью охарактеризованную формулу стромально-васкулярной фракции (СВФ). Дизайн исследования включает 3 группы: 1-я группа (контрольная) – хирургическое моделирование костных дефектов в областях диафиза контралатеральной бедренной кости без реконструкции; 2-я группа – замещение костного дефекта фрагментами депротеинизированной губчатой кости; 3-я группа – замещение костного дефекта с использованием фрагментов депротеинизированной губчатой кости совместно с аутологичной СВФ жировой ткани (полученную по технологии ACP SVF). Животных выводили из эксперимента под эфирным наркозом через 2, 4 и 6 недель после операции, с последующим гистологическим исследованием.</p></sec><sec><title>Результаты</title><p>Результаты. Во все сроки исследования объемная плотность новообразованной костной ткани в 3-й группе (реконструкция депротеинизированной губчатой костью человека со стромально-васкулярной фракцией) была в 1,78 раза выше (р &lt; 0,001), чем в 1-й группе (дефект костной ткани без реконструкции), в 1,21 раза выше (р &lt; 0,001), чем во 2-й группе (реконструкция депротеинизированной губчатой костью). Динамика изменения объемной плотности зрелой костной ткани была аналогична динамике изменения объемной плотности новообразованной костной ткани.</p></sec><sec><title>Обсуждение</title><p>Обсуждение. Сравнительный анализ репаративных процессов с использованием тканеинженерной конструкции на основе депротеинизированной губчатой кости совместно со стромально-васкулярной фракцией жировой ткани показал, что применение данного костнозамещающего материала способствует не только ранней активации репаративной регенерации основных структурных элементов костной ткани в области замещения дефекта, но и своевременной их дифференцировки.</p></sec><sec><title>Выводы</title><p>Выводы. Использование депротеинизированной губчатой кости совместно со стромально-васкулярной фракцией для создания тканеинженерной конструкции позволяет реализовать ряд процессов регенерации и ускорить процесс восстановления дефекта кости по сравнению с 1-ой и 2-ой группой исследования.</p></sec></abstract><trans-abstract xml:lang="en"><p>Background Management of bone defects with autologous bone grafting has always been the "gold standard" but it is not always possible to use it for a number of reasons. Preprocessed materials of biological and non-biological origin were developed as an alternative. A new branch of these materials is tissue-engineered constructs that fully imitate autologous bone in required volume.</p><p>Aim is to study in vivo the possibility of using deproteinized human cancellous bone tissue as a matrix for creating tissue-engineered constructs.</p><p>Methods The study was carried out on 24 NZW line rabbits, since this line has a fully characterized stromal-vascular fraction formula (SVF). The study design included 3 groups. First group (control) had surgical modeling of bone defects in the diaphysis of the contralateral femur without reconstruction; Group 2 had bone defect reconstruction using fragments of a deproteinized cancellous bone graft; group 3 underwent bone defect reconstruction using fragments of deproteinized cancellous bone matrix along with the autologous adipose tissue SVF (obtained according to ACP SVF technology). Animals were sacrificed with ether anesthesia at 2, 4 and 6 weeks after the operation and subsequent histological study followed.</p><p>Result During all periods of the study, the newly formed bone tissue volume density in the 3rd group (reconstruction with deproteinized human cancellous bone + stromal-vascular fraction) was 1.78 times higher (p &lt; 0.001) than in the first group (bone defect without reconstruction), 1.21 times higher (p &lt; 0.001) than in the 2nd group (reconstruction with deproteinized cancellous bone alone). The dynamics of changes in the mature bone tissue volume density was similar to those of the newly formed bone tissue.</p><p>Discussion The comparative analysis of reparative processes using a tissue engeneered construst based on deproteinized cancellous human bone with adipose tissue stromal vascular fraction revealed that the use of these bone substitute materials contributes not only to the early activation of reparative regeneration of the main structural elements of bone tissue at the site of bone defect, but also their timely differentiation.</p><p>Conclusion The use of deproteinized cancellous bone matrix combined with stromal-vascular fraction to create a tissue-engineered construct could unleash several regeneration mechanisms and accelerate the process of bone defect site repair, compared with 1st and 2nd group of study.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>костный дефект</kwd><kwd>депротеинизированная губчатая кость</kwd><kwd>замещение костного дефекта</kwd><kwd>стромально-васкулярная фракция жировой ткани</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Bone defect</kwd><kwd>bone matrices</kwd><kwd>deproteinized cancellous bone</kwd><kwd>bone defect reconstruction</kwd><kwd>adipose tissue stromal-vascular fraction</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was carried out within the framework of state assignment No АААА-А18-118030690022-4 "Development of biomedical regenerating implants for traumatology and orthopedics".</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">Gurazhev MB, Baitov VS, Gavrilov AA, et al.
