В работе использовано 19 атимичных мышей BALB/c nu/nu, которым после сублетального облучения в соответствии с протоколом гуманизации внутрибрюшинно вводили 1×106 CD8+. Перевивку опухоли, полученной от пациента 64 лет, проводили последовательно троекратно. Образцы исходной и ксенографтной опухоли в автоматическом режиме окрашивали гематоксилином и эозином, кроличьими антителами к CK7, TTF и Ki67. Оценку гистологических препаратов осуществляли согласно рекомендациям ВОЗ (2015).</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что опухоль третьей генерации, развивающаяся в организме атимичных гуманизированных мышей, сохраняет морфологические и иммуногистохимические черты исходной опухоли пациента. Описанный подход может быть использован в доклинических и персонализированных исследованиях в фундаментальной фармакологии и молекулярной онкологии.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to carry out a comparative morphological and immunohistochemical analysis of peripheral non-small cell lung cancer, which served as a source of a xenograft tumor, and tissues of the third generation of a tumor that developed in animals.</p><sec><title>Material and methods</title><p>Material and methods. We used 19 athymic BALB/c nu/nu mice, which were intraperitoneally injected with 1×106 CD8+ after sublethal irradiation in accordance with the humanization protocol. The transplantation of a tumor obtained from a 64-year-old patient was carried out three times consecutively. Samples of the original and xenograft tumors were automatically stained with hematoxylin and eosin, rabbit anti-CK7, anti-TTF, and anti-Ki67 antibodies. The evaluation of histological samples was carried out in accordance with the WHO recommendations (2015).</p></sec><sec><title>Results</title><p>Results. It has been established that a third-generation tumor developing in the body of athymic humanized mice retains the morphological and immunohistochemical features of the patient's original tumor. The described approach may be used in preclinical and personalized studies in fundamental pharmacology and molecular oncology.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>немелкоклеточный рак легкого</kwd><kwd>ксенографт</kwd><kwd>морфологическая валидация</kwd><kwd>иммуногистохимия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>non-small cellular lung cancer</kwd><kwd>xenograft</kwd><kwd>morphological validation</kwd><kwd>immunohistochemistry</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование выполнено при финансовой поддержке гранта Президента Российской Федерации НШ-843.2022.3 (соглашение №075-15-2022-842 от 12 мая 2022 г.).</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The study was supported by the grant of the President of the Russian Federation NSh-843.2022.3 (agreement No. 075-15-2022-842 dated May 12, 2022).</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">Siegel RL, Miller KD, Jemal A.
