В литературе описаны ИПСК собаки (Canis lupus familiaris) и снежного леопарда (Panthera uncia), представителей отряда Carnivora. Ранее нами получены ИПСК американской норки (Neovison vison). Целью настоящего исследования был поиск условий для репрограммирования фибробластов ластоногих – представителей каноидной (Caniformia) ветви Хищных с консервативными геномами. Для создания ИПСК можно использовать различные системы доставки репрограммирующих транскрипционных факторов (РНК, белки, плазмиды, векторы на основе вирусов и др.). Наиболее эффективные системы доставки для клеток мыши и человека основаны на применении различных вирусных векторов. Мы сравнили две системы доставки репрограммирующих факторов: встраивающиеся в геном лентивирусные векторы и вектор на основе вируса Сендай – CytoTune EmGFP Sendai Fluorescence Reporter. Преимущества векторов на основе вируса Сендай по сравнению с лентивирусами – отсутствие встройки в геном. Проведено тестирование доставки генетических конструкций, кодирующих флуоресцентный белок, на культурах фибробластов семи видов ластоногих: северного морского котика (Callorhinus ursinus), северного морского льва (Eumetopias jubatus), моржа (Odobenus rosmarus), морского зайца (Erignathus barbatus), байкальской нерпы (Pusa sibirica), кольчатой нерпы (Phoca hispida) и пестрой нерпы (Phoca largha). В качестве контроля были трансдуцированы фибробласты американской норки (N. vison), человека (Homo sapiens) и мыши (Mus musculus). Мы показали, что система трансдукции на основе вируса Сендай обеспечивает уровень экспрессии трансгена на один­два порядка выше, чем при использовании лентивирусов при сходном числе вирусов на клетку. Кроме того, экспрессия трансгена при применении вектора на основе вируса Сендай достаточно стабильна и незначительно изменяется на четвертый день трансдукции по сравнению со вторым днем. Полученные данные позволяют предположить, что трансдукция фибробластов ластоногих с помощью вируса Сендай предпочтительна для получения ИПСК ластоногих.</p></abstract><trans-abstract xml:lang="en"><p>Generation of induced pluripotent stem (iPS) cells expanded possibilities of pluripotency and early development studies. Generation of order Carnivora iPS cells from dog (Canis lupus familiaris), snow leopard (Panthera uncia), and American mink (Neovison vison) was previously reported. The aim of the current study was to examine conditions of pinniped fbroblast reprogramming. Pinnipeds are representatives of the suborder Caniformia sharing conservative genomes. There are several ways to deliver reprogramming transcription factors: RNA, proteins, plasmids, viral vectors etc. The most eﬀective delivery systems for mouse and human cells are based on viral vectors. We compared a lentiviral vector which integrates into the genome and a Sendai virus­based vector, CytoTune EmGFP Sendai Fluorescence Reporter. The main advantage of Sendai virus­based vectors is that they do not integrate into the genome. We performed delivery of genetic constructions carrying ﬂuorescent proteins to fbroblasts of seven Pinnipeds: northern fur seal (Callorhinus ursinus), Steller sea lion (Eumetopias jubatus), walrus (Odobenus rosmarus), bearded seal (Erignathus barbatus), Baikal seal (Pusa sibirica), ringed seal (Phoca hispida), and spotted seal (Phoca largha). We also transduced American mink (N. vison), human (Homo sapiens), and mouse (Mus musculus) fbroblasts as a control. We showed that the Sendai virus­based transduction system provides transgene expression one­two orders of magnitude higher than the lentiviral system at a comparable multiplicity of infection. Also, transgene expression after Sendai virus­based transduction is quite stable and changes only slightly at day four compared to day two. These data allow us to suggest that Sendai virus­based vectors are preferable for generation of Pinniped iPS cells.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Хищные</kwd><kwd>тюлени</kwd><kwd>морж</kwd><kwd>репрограммирование</kwd><kwd>ИПСК</kwd><kwd>вирус Сендай</kwd><kwd>CytoTune EmGFP Sendai Fluorescence Reporter</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Carnivora</kwd><kwd>seals</kwd><kwd>walrus</kwd><kwd>reprogramming</kwd><kwd>iPS cells</kwd><kwd>Sendai virus</kwd><kwd>CytoTune EmGFP Sendai Fluorescence Reporter</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">Борода А.В., Питерсон С.Е., Монтэгю С.К., Пиварофф К.Дж., Штейн Дж., Ли Ч.Я., Лорин Дж.Ф., Одинцова Н.А.
