Ранее были проведены многочисленные исследования, направленные на изучение особенностей поведения и физиологии крыс этой линии в период постнатальной жизни, однако преимплантационное развитие эмбрионов линии OXYS до сих пор не изучено. В настоящей работе исследовано преимплантационное развитие эмбрионов крыс линии OXYS как в условиях in vivo, так и при культивировании in vitro. В качестве контроля для всех экспериментов служила линия крыс WAG. Для исследования преимплантационного развития in vivo у крыс линий OXYS и WAG на 5-й день беременности из репродуктивных путей извлекали эмбрионы. У эмбрио нов оценивали стадию развития и долю зародышей, достигших стадии бластоцисты, подсчитывали число клеток, входящих в состав бластоцисты. При изучении особенностей культивирования в условиях in vitro эмбрионы двух линий крыс извлекали из репродуктивных путей на сутки раньше, на 4-й день беременности, на стадии дробления эмбрионов. Такие эмбрионы, состоящие всего из восьми бластомеров на данной стадии развития, культивировали in vitro в течение 48 ч в среде P1 в присутствии ростового фактора IGF-1 (200 нг/мл) либо без него. После культивирования у эмбрионов крыс так же, как и в эксперименте по оценке развития эмбрионов in vivo, подсчитывали долю зародышей, достигших стадии бластоцисты, и оценивали число клеток, представленных в бластоцисте. В статье показано, что на 5-е сутки развития в репродуктивных путях самок крыс линии OXYS представлено большее число эмбрионов по сравнению с линией WAG. Развившиеся в условиях in vivo бластоцисты крыс линии OXYS на 5-е сутки содер жат меньшее число клеток по сравнению с эмбрионами линии WAG. Культивирование ранних эмбрионов крыс линии OXYS и WAG в среде P1 нивелирует различия в скорости развития между этими линиями, а присутствие IGF-1 в культуральной среде не оказывает ни положительного, ни отрицательного эффекта на их развитие в условиях in vitro</p></abstract><trans-abstract xml:lang="en"><p>OXYS rats are the model of precocious senescence. Numerous studies addressed physiology and behavior in rats of this strain during a postnatal period of their life, however, preimplantation development in OXYS rats has not yet been investigated. This study is addressing preimplantation embryonic development in OXYS rats both in vivo and in vitro. Rats of the WAG strain were used as controls. For studying the in vivo development, the embryos were collected from OXYS and WAG rats on day 5 post coitum, the stages of embryo development were estimated, the percentage of embryos at blastocyst stage and the cell numbers in these blastocysts were counted. In a special experiment, for studying in vitro development, the embryos were collected from both rat strains on day 4 post coitum and were cultured in vitro in P1 medium for 48 hours with or without supplementation with IGF-1 (200 ng/mL). Thereafter the percentage of embryos at blastocyst stage and the cell numbers in these blastocysts were counted in the same manner as for the in vivo experiment. This study reports that in vivo derived blastocysts of OXYS rats contain fewer cells on day 5 of their development than in vivo derived blastocysts of WAG rats. In vitro culture of the early preimplantation embryos in P1 medium mitigated the difference in the rate of embryo development between these two strains, the addition of IGF-1 into culture medium exerts neither negative nor positive effect on the rate of in vitro embryo development in rats of both strains.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>крысы OXYS</kwd><kwd>крысы WAG</kwd><kwd>преимплантационное развитие in vivo</kwd><kwd>культивирование in vitro</kwd><kwd>эмбрионы</kwd><kwd>IGF-1</kwd></kwd-group><kwd-group xml:lang="en"><kwd>OXYS rats</kwd><kwd>WAG rats</kwd><kwd>in vivo preimplantation development</kwd><kwd>in vitro culture</kwd><kwd>embryos</kwd><kwd>IGF-1</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">Berryman D.E., Christiansen J.S., Johannsson G., Thorner M.O., Kop-chick J.J.
