Спонтанные хромосомные аберрации в линиях индуцированных плюрипотентных стволовых клеток (иПСК) обнаруживаются с частотой около 20%, что препятствует их дальнейшему использованию в исследовательских и медицинских целях. Одним из наиболее рациональных подходов к рутинному контролю генетической стабильности иПСК является таргетное выявление рекуррентных аномалий кариотипа, 20-60% которых может составлять трисомия по хромосоме 12. Трисомия 12 приводит к нарушению способности к дифференцировке, динамики репликации и сопровождается быстрым вытеснением эуплоидного клона.</p></sec><sec><title>Цель</title><p>Цель. Разработка протокола получения флуоресцентных ДНК-зондов, специфичных к перицентромерным повторам хромосомы 12, для выявления анеуплоидии методом FISH.</p></sec><sec><title>Результаты</title><p>Результаты. Разработан двухстадийный протокол получения ДНК-зондов на основе ПЦР с геномной ДНК в качестве матрицы с последующим клик-химическим прямым мечением флуорохромом. На линиях иПСК с известными эуплоидным и анеуплоидным кариотипами отработаны условия гибридизации и подтверждена эффективность и специфичность выявления хромосомы 12 на метафазных пластинках и в интерфазных ядрах.</p></sec><sec><title>Выводы</title><p>Выводы. FISH с собственными несерийными ДНК-зондами повышает доступность исследования копийности хромосомы 12 в иПСК, что способствует своевременному выявлению функционально значимых генетических нарушений в клеточных линиях.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Approximately 20% of induced pluripotent stem cell (iPSC) lines spontaneously acquire chromosomal abnormalities, which hinders their use in research and medical applications. One rational approach for routine monitoring of genetic stability in iPSCs is the targeted detection of recurrent karyotype anomalies, 20-60% of which may involve trisomy of chromosome 12. Trisomy 12 leads to impaired differentiation capacity and replication dynamics and is associated with the rapid displacement of the euploid clone.</p></sec><sec><title>Aim</title><p>Aim. To develop a protocol for the production of fluorescent DNA probes for the detection of chromosome 12 aneuploidy.</p></sec><sec><title>Results</title><p>Results. A two-stage protocol for obtaining DNA probes based on PCR, using genomic DNA as the template, has been developed, followed by direct click-labeling with a fluorochrome. Hybridization conditions have been optimized for iPSC lines with known euploid and aneuploid karyotypes, confirming the effectiveness and specificity of detecting chromosome 12 on metaphase spreads and in     interphase nuclei.</p></sec><sec><title>Conclusions</title><p>Conclusions. FISH using custom DNA probes enhances the availability of chromosome 12 copy number analysis in laboratories, facilitating the timely detection of functionally significant genetic abnormalities in cell lines.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>FISH</kwd><kwd>индуцированные плюрипотентные стволовые клетки</kwd><kwd>иПСК</kwd><kwd>хромосома 12</kwd><kwd>центромера</kwd><kwd>анеуплоидия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>FISH</kwd><kwd>induced pluripotent stem cells</kwd><kwd>IPSC</kwd><kwd>chromosome 12</kwd><kwd>centromere</kwd><kwd>aneuploidy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Минобрнауки России для ФГБНУ МГНЦ.</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">Deng C., Ya A., Compton D.A., Godek K.M.
