Bioimaging based on luminescent systems, compared with fluorescent bioimaging, provides a high signal-to-noise ratio, which justifies the development of cell lines, that stably express luciferase genes for subsequent use in model animals. The work describes the creation of a stable cell line SKOV3.ip1-NanoLuc constitutively expressing the NanoLuc luciferase gene. The developed cell line was shown to be effective for intravital luminescence bioimaging of immunodeficient animals with deep-seated intraperitoneal tumors, which can be considered as a model of late-stage ovarian cancer.</p></abstract><trans-abstract xml:lang="ru"><p>Метод прижизненного биоимиджинга на основе люминесценции занимает важное место в разработке и тестировании противоопухолевых препаратов на модельных животных и является неотъемлемой частью доклинических исследований. Биоимиджинг на основе люминесцентных систем, по сравнению с флуоресцентным биоимиджингом, обеспечивает высокое соотношение сигнал/шум, что обосновывает разработку клеточных линий, стабильно экспрессирующих ген люциферазы, для последующего использования на модельных животных. В работе описано создание клеточной линии SKOV3.ip1-NanoLuc, конститутивно экспрессирующей ген люциферазы NanoLuc. Показано эффективное применение разработанной клеточной линии для прижизненного люминесцентного биоимидижинга глубинных опухолей у иммунодефицитных животных с моделями поздних стадий рака яичника.</p></trans-abstract><kwd-group xml:lang="en"><kwd>NanoLuc luciferase, ovarian cancer adenocarcinoma, stable cell line, bioimaging</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>люцифераза NanoLuc</kwd><kwd>аденокарцинома рака яичника</kwd><kwd>стабильная клеточная линия</kwd><kwd>биоимиджинг</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap></funding-source><award-id>24-14-00088</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Tuguntaev R.G., Hussain A., Fu C., et al.
