Заро­дыши как мышей, так и крыс вначале замораживали, согласно стандартному протоколу программного замораживания с использованием глицерина и сахарозы в качестве криопротек­торов, а после размораживания культивировали в среде R1ECM (rat 1-cell embryo culture medium) в течение либо 24 ч (мыши), либо 72 ч (крысы). Эффекты факторов роста на мышах изучали на 8-клеточных, а на крысах – на 2-, 4-клеточных зародышах. Воздействие GM-CSF приводило к возрастанию процента развивающихся эмбрионов у мышей обеих линий (HT1AC/Icgn и C57BL/6J-Ay ); в то же время какого-либо эффекта воздействия EGF на зародыши мышей обнаружено не было. На крысах ситуация была обратной. Воздействие EGF приводило к ускорению разви­тия до стадии бластоцисты у крыс линии OXYS/Icgn, но какого-либо эффекта воздействия GM-CSF на зародыши крыс не было. При совместном культивиро­вании 4-клеточных эмбрионов мышей линии HT1AN/Icgn с более поздними стадиями развития (зародышами на стадии морулы) линии ICR, наблюдается ускорение развития. Результаты представленных экспериментов свидетельствуют о видовой специфике воздей­ствия факторов роста на эмбрионы мышей и крыс, а также демонстрируют, что совместное культивирование эмбрионов более поздних стадий (морулы) мышей с более ранними (4-клеточные зародыши) оказывает стимулирующее влияние на последние.</p></abstract><trans-abstract xml:lang="en"><p>In vitro culture of preimplantation embryos of ICR, HT1AN/Icgn, HT1AC/Icgn and C57BL/6J-Ay mouse strains as well as in OXYS/Icgn rat strain in media containing granulocyte-macrophage colony stimulating factor (GM-CSF) or epidermal growth factor (EGF) has been studied. Both mouse and rat embryos were first frozen in a programmable freezer after a standard protocol using a mixture of glycerol and sucrose as cryoprotectants, thawed and cultured in vitro in R1ECM (rat one-cell embryo culture medium) for 24 hours (mice) and 72 hours (rats). For the in vitro culture experiments with these growth factors, 8-cell frozen-thawed mouse embryos and 2–4-cell frozen-thawed rat embryos were used. Supplementation of the culture medium with GM-CSF improved the rate of embryonic development in HT1AC/Icgn and C57BL/6J-Ay strain mice, while EGF had no effect. The reverse was true of the rats. Supplementation of the culture medium with EGF increased the percentage of deve­loping blastocysts in OXYS/Icgn rat strain, while GM-CSF had no effect. Co-culture of four-cell embryos of HT1AN/ Icgn strain mice with more advanced embryonic stages (morulas) of a different strain ICR led to the facilitation preimplantation embryo development. Experimental results presented here reveal the species-specific effects of growth factors on mouse and rat embryos and indicate that co-culture of different stages of embryo development have stimulatory effects on earlier stages.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>преимплантационные эмбрионы</kwd><kwd>культивирование in vitro</kwd><kwd>факторы роста</kwd><kwd>мыши</kwd><kwd>крысы</kwd><kwd>сокультивирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>preimplantation embryos</kwd><kwd>in vitro culture</kwd><kwd>growth factors</kwd><kwd>mice</kwd><kwd>rats</kwd><kwd>co-culture</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>ИЦиГ СО РАН, Минобрнауки России, РФФИ, Е.А.Галустян, ЦКП «Виварий конвенциональных животных» и «SPFвиварий»</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">Амстиславский С.Я., Игонина Т.Н., Рожкова И.Н., Брусенцев Е.Ю., Роговая А.А., Рагаева Д.С., Напримеров В.А., Литвинова Е.А., Плюснина И.Ф., Маркель А.Л.
