Определить содержание опухолевых клеток с фенотипом стволовых (ОСК) в ткани опухоли и перитуморальной зоне при мышечно-неинвазивном раке мочевого пузыря (МНИРМП).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследованы фрагменты опухолевой ткани (ОП) и ткани перитуморальной зоны (ПЗ) 7 пациентов с впервые выявленным мышечно-неинвазивным раком мочевого пузыря (МНИРМП) после проведения оперативного вмешательства в объеме трансуретральной резекции мочевого пузыря (ТУР). В образцах тканей, которые использовались для получения клеточной суспензии ОП и ПЗ с помощью аппарата BD Medimachine (BD, USA), с использованием моноклональных антител CD45-APC-Cy7, CD44-FITC, CD133-РЕ, CD24-PE (BD, USA), осуществляли определение фенотипических характеристик клеток на проточном цитометре FacsCantoII (BD, USA). В анализируемых образцах определяли процентное содержание клеток с фенотипом стволовых: CD45-CD44+CD24+, CD45-CD44+, CD45-CD24+, CD45-CD133+, CD45-CD44+CD133+. Наличие достоверности различий в группах оценивали при помощи программного пакета Statistica 13, различия между выборками считали достоверными при р &lt; 0,05. Расчёт процентного содержание клеток соответствующего фенотипа производился относительно общего числа клеток.</p></sec><sec><title>Результаты</title><p>Результаты. Относительное содержание клеток, имеющих фенотипические маркеры ОСК такие как CD24, CD44, в ОП были на 77 % и 58 % больше, чем в ПЗ, соответственно 18,3 ± 3,5 против 4,3 ± 2,1, р ≤ 0,044 15,5 ± 5,3 против 6,5 ± 0,8, р ≤ 0,043. Количество CD133+ – клеток оказалось больше на 83 % в ПЗ по сравнению с ОП – 41,6 ± 12,1 против 22,7 ± 7,6, р ≤ 0,047.</p></sec><sec><title>Заключение</title><p>Заключение. Изучение опухолевых стволовых клеток в настоящее время является перспективным направлением для изучения развития злокачественного процесса и может быть использовано для предикции и оценки характера дальнейшего развития рецидива и/или прогрессирования заболевания, а также, в дальнейшем, для применения различных подходов терапии, которые будут направлены на устранение клеток с фенотипом стволовых и блокирования путей, которые приводят к возникновению и поддержанию данной популяции клеток у больных с МНИРМП.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. Determine the content of cancer stem cells (CSCs) in the tumor tissue (TT) and perifocal tissues (PT) in muscle-non-invasive bladder cancer.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. We’ve examined fragments of TT and PT of 7 muscle-non-invasive bladder cancer (NMIBC) after surgical intervention – transurethral resection of the urinary bladder (TUR). In tissue samples that were used to obtain cell suspension of TT and PT using the BD Medimachine apparatus (BD, USA) was treated with monoclonal antibodies CD45-APCCy7, CD44-FITC, CD133-РЕ, CD24-PE (BD, USA) and were assessed on flow cytometer FacsCantoII (BD, USA). The percentage of cells with CSC phenotypic markers was determined in the analysis sample: CD45-CD44+CD24+, CD45-CD44+, CD45-CD24+, CD45-CD133+, CD45-CD44+CD133+. The presence of significant differences in the groups was evaluated using the STATISTICA 13 software package and the differences between the samples were considered significant at p &lt; 0.05. The percentage of cells of the corresponding phenotype was calculated relative to the total number of cells. The percentage of cells with the corresponding phenotype was calculated relative to the total number of cells.</p></sec><sec><title>Results</title><p>Results. The relative numbers of cells with CSC phenotypic markers, such as CD24, CD44, were 77 % and 58 % higher in TT than in PT: 18.3 ± 3.5 vs. 4.3 ± 2.1, p ≤ 0.044 and 15.5 ± 5.3 vs. 6.5 ± 0.8, p ≤ 0.043, respectively. The number of CD133+ cells was 83 % higher in PT compared to TT – 41.6 ± 12.1 vs. 22.7 ± 7.6, p ≤ 0.047.</p></sec><sec><title>Conclusion</title><p>Conclusion. The study of CSCs is a promising direction for the study of oncogenesis and can be used to assess the nature of the further development of relapse and / or progression of the disease, as well as various therapeutic approaches that are aimed at eliminating with CSC phenotypic markers and blocking the pathways leading to the emergence and maintenance of this cell population in patients with NMIBC.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>мышечно-неинвазивный рак мочевого пузыря</kwd><kwd>опухолевые стволовые клетки</kwd><kwd>перитуморальная зона</kwd></kwd-group><kwd-group xml:lang="en"><kwd>non-muscle-invasive bladder cancer</kwd><kwd>cancer stem cells</kwd><kwd>perifocal tissues</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">Кит О.
