Культивирование доимплантационных зародышей млекопитающих вне организма является необходимым звеном при проведении экспериментально-эмбриологических исследований, а также эмбриотехнологических работ по клонированию и получению трансгенных животных. Нормальный рост и дифференцировка эмбрионов млекопитающих in vitro во время доимплантационного периода зависят от наличия соответствующих метаболических субстратов. Вот почему так важно подобрать оптимальные условия культивирования при работе с микроинъецированными эмбрионами, поскольку любые манипуляции снижают их жизнеспособность, что особенно важно при получении трансгенных животных.</p><p>Для определения наиболее эффективной культуральной среды нами было проведено исследование выживаемости эмбрионов мыши после микроинъекции генно-инженерной конструкции в пронуклеусы и дальнейшего культивирования на питательных средах М16 и Onestep. Было отмечено увеличение количества эмбрионов, развившихся до стадии двух бластомеров на среде Onestep, по сравнению со средой М16. Также были выявлены различия в двух контрольных группах, эмбрионы в которых не подвергались микроинъекции, но культивировались на этих же средах в тех же условиях, что и эмбрионы опытных групп. Более эффективной средой для культивирования интактных эмбрионов оказалась среда Onestep, в которой процент выживших эмбрионов был больше, чем в среде М16. </p></abstract><trans-abstract xml:lang="en"><p>The normal growth and differentiation of mammalian embryos in vitro during the pre-implantation period depends on the availability of appropriate metabolic substrates. Selection of optimal cultivation conditions when working with microinjected embryos is of significance, since any manipulations can reduce their viability. This is particularly important when obtaining transgenic animals. In order to determine the most effective culture medium, we studied the survival of mouse embryos after the microinjection of a genetically engineered construct into the pronuclei and further cultivation on the M16 and Onestep nutrient media. Compared to the M16 medium, an increase in the number of embryos that developed to the stage of two blastomeres on the Onestep medium was observed. Differences were also revealed in the two control groups, the embryos in which were not subjected to microinjection, but were cultured on the same media under the same conditions as the embryos of the experimental groups. We found that the Onestep medium, in which the percentage of survived embryos exceeded that in the M16 medium, is a more efficient medium for the cultivation of intact embryos. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>эмбрион</kwd><kwd>культуральная среда</kwd><kwd>микроинъекция в пронуклеусы зигот</kwd><kwd>трансгеноз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>embryo</kwd><kwd>culture medium</kwd><kwd>microinjection into zygote pronuclei</kwd><kwd>transgenosis</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">Вильянович Л.И., Кривохарченко А.С.
