One of the most perspective trends in this field is using induced pluripotent stem cells (iPSCs). iPSC application requires careful high-throughput analysis at the molecular, epigenetic, and functional levels. The methods used have revealed that the expression pattern of genes and microRNA, DNA methylation, as well as the set and pattern of covalent histone modifications in iPSCs, are very similar to those in embryonic stem cells. Nevertheless, iPSCs have been shown to possess some specific features that can be acquired during the reprogramming process or are remnants of epigenomes and transcriptomes of the donor tissue. These residual signatures of epigenomes and transcriptomes of the somatic tissue of origin were termed “epigenetic memory.” In this review, we discuss the “epigenetic memory” phenomenon in the context of the reprogramming process, its influence on iPSC properties, and the possibilities of its application in cell technologies.</p></abstract><trans-abstract xml:lang="ru"><p>Современная биомедицина и фармакология требуют создания новых, более совершенных клеточных моделей заболеваний. Одним из перспективных направлений в данной области является применение индуцированных плюрипотентных стволовых клеток (ИПСК), получаемых путем репрограммирования соматических клеток. Однако для полноценного использования данной технологии необходимо тщательное изучение ИПСК на молекулярном, эпигенетическом и функциональном уровнях. Современные методы анализа свидетельствуют о том, что ИПСК очень схожи с эмбриональными стволовыми клетками (ЭСК) по профилю экспрессии белоккодирующих генов, генов микроРНК, метилированию ДНК, спектру и паттерну распределения ковалентных модификаций гистонов. Тем не менее показано, что ИПСК обладают характерными особенностями, приобретенными как в процессе репрограммирования, так и в результате сохранения ряда черт эпигеномов и транскриптомов исходных соматических клеток-предшественников. Явление сохранения черт эпигеномов и транскриптомов исходных соматических клеток получило название «эпигенетическая память». Данный обзор посвящен явлению «эпигенетической памяти» в контексте процесса репрограммирования, влиянию «памяти» на свойства ИПСК, а также возможности ее использования в клеточных технологиях.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pluripotency</kwd><kwd>reprogramming</kwd><kwd>epigenetics</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>плюрипотентность</kwd><kwd>репрограммирование</kwd><kwd>эпигенетика</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by the Ministry of Education and Science of the Russian Federation (Agreement № 8264) and the Russian Foundation for Basic Research (Grants № 11-04-00847-a, 12-04-00185-a and 12-04-00208-a).</funding-statement><funding-statement xml:lang="ru">Работа поддержана Министерством образования и науки Российской Федерации (соглашение № 8264) и РФФИ (гранты № 11-04-00847-а, 12-04-00185-а и 12-04-00208-а).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>[1] Bernstein B.E., Mikkelsen T.S., Xie X., Kamal M., Huebert D.J., Cuff J., Fry B., Meissner A., Wernig M., Plath K. // Cell. 2006, V.125, №2, P.315-326</mixed-citation></ref><ref id="B2"><label>2.</label><mixed-citation>[2] Spivakov M., Fisher A.G. // Nat.
