New model systems for studying the processes of malignant transformation of hematopoietic cells are needed. Based on cytokine-dependent murine acute myeloid leukemia (AML) FDC-P1 cells, we generated a new cell line with ectopic expression of the <italic>KIT</italic> gene encoding mutant human receptor tyrosine kinase (N822K). We investigated the role played by overexpression of the mutant <italic>KIT</italic> in the survival of leukemia cells and their sensitivity to therapeutic drugs. We also generated a co-culture system consisting of FDC-P1 murine leukemia cells and a HS-5 human stromal cell line. Our data can be used for a further comprehensive analysis of the role of <italic>KIT</italic> N822K mutation in the cellular response to anti-leukemic drugs, growth factors, and cytokines. These data are of interest in the development of new effective therapeutic approaches to the treatment of acute leukemia.</p></abstract><trans-abstract xml:lang="ru"><p>Для изучения процессов злокачественного перерождения кроветворных клеток и механизмов развития резистентности лейкозных клеток к химиотерапевтическим препаратам необходимы новые модельные системы. На основе цитокинзависимой мышиной клеточной линии FDC-P1 острого миелоидного лейкоза (ОМЛ) нами получены перевиваемые клетки с эффективной эктопической экспрессией мутантного гена <italic>KIT</italic> <italic>N</italic><italic>822</italic><italic>K</italic> человека. Изучена роль повышенной экспрессии мутантного <italic>KIT</italic> в выживаемости и чувствительности этих клеток к терапевтическим препаратам. Также создана и охарактеризована смешанная культура, состоящая из линии FDC-P1 лейкозных клеток мыши и линии HS-5 стромальных клеток человека. Полученные результаты могут быть использованы для изучения роли мутаций N822K в гене <italic>KIT</italic> в ответе клеток на противолейкозные препараты, факторы роста и цитокины. Эти данные представляют интерес для разработки эффективных подходов к терапии лейкозов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>receptor tyrosine kinase KIT</kwd><kwd>FDC-P1</kwd><kwd>acute myeloid leukemia (AML)</kwd><kwd>KIT N822K</kwd><kwd>stromal cells</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>острый миелоидный лейкоз (ОМЛ)</kwd><kwd>рецепторная тирозинкиназа KIT</kwd><kwd>FDC-P1</kwd><kwd>KIT N822K</kwd><kwd>стромальные клетки</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский Фонд Фундаментальных Исследований</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Foundation for Basic Research</institution></institution-wrap></funding-source><award-id>18-29-09151</award-id></award-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский Фонд Фундаментальных Исследований</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Foundation for Basic Research</institution></institution-wrap></funding-source><award-id>17-04-01555</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Hassan H.T. // Leuk.
