Создание перевиваемой ортотопической PDX-модели рака желудка на иммунодефицитных мышах линии Balb/c Nude при помощи имплантационного и инъекционного способов.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. С целью создания ортотопической PDX-модели рака желудка человека были применены 2 способа – инъекционный и имплантационный. Первый способ заключался в инъекции суспензии механически дезагрегированной опухоли пациента после фильтрации в стенку желудка мышей линии Balb/c Nude. Для второго способа мелкие фрагменты (3 × 3 × 3 мм) опухоли пациентов были имплантированы мышам в стенку желудка по большой кривизне с рассечением серозно-мышечного слоя.</p></sec><sec><title>Результаты</title><p>Результаты. При применении имплантационного способа получения PDX-модели рака желудка на иммунодефицитных мышах линии Balb/c Nude в ходе процедур контрольной лапаротомии, был обнаружен положительный результат приживления опухолевого материала при 1‑ой и 3‑ей процедурах. Инъекционный способ не дал эффективного результата–не была получена ни одна модель. Гистотип полученных PDX-моделей сравнивали с донорской опухолью и подтверждали при помощи гистологического исследования (окрашивание гематоксилином и эозином). Степень дифференцировки оставалась стабильной и не менялась в результате пассирования ксенографта, что показало идентичность полученной модели гистотипу донорской опухоли.</p></sec><sec><title>Заключение</title><p>Заключение. Представленный имплантационный метод создания модели дает эффективный результат приживления опухоли. Полученная модель позволяет использовать её для проверки эффективности противоопухолевых или антиметастатических препаратов, возможных исследований функций биомаркеров, а также для оценки микроокружения опухоли желудка.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. Creation of a transplantable orthotopic PDX model of gastric cancer in Balb/c Nude immunodeficient mice using implantation and injection.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Two methods, that are injection and implantation, were used to create an orthotopic PDX model of human gastric cancer. The first method involved injections of a suspension of a mechanically disaggregated patient's tumor after filtration into the gastric wall of Balb/c Nude mice. For the second method, small fragments (3 × 3 × 3 mm) of patients' tumors were implanted in the gastric wall of mice along the greater curvature with a dissection of the serous muscular layer.</p></sec><sec><title>Results</title><p>Results. Control laparotomy in Balb/c Nude immunodeficient mice showed a successful engraftment of the tumor material at the 1st and 3rd procedures when using the implantation method for the creation of a PDX model of gastric cancer. The injection method was ineffective, and no models were created. The histological type of the obtained PDX models was compared to the type of the donor tumor by histological examination (hematoxylin and eosin staining). The tumor grade remained stable and did not change during xenograft passage, which showed that the obtained model was identical to the histotype of the donor tumor.</p></sec><sec><title>Conclusion</title><p>Conclusion. The presented implantation method for the model creation results in effective tumor engraftment. The developed model can be used to test the effectiveness of anticancer or antimetastatic drugs, for studying the functions of biomarkers, or in assessing the microenvironment of a gastric cancer.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ортотопическая ксенотрансплантация</kwd><kwd>рак желудка</kwd><kwd>иммунодефицитные мыши</kwd><kwd>PDX-модели</kwd><kwd>трансплантация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>orthotopic xenotransplantation</kwd><kwd>gastric cancer</kwd><kwd>immunodeficient mice</kwd><kwd>PDX models</kwd><kwd>transplantation</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">Sung H, Ferlay J, Siegel RL, Laversanne M, Soerjomataram I, Jemal A, et al.
