It was revealed, that despite of the expressed heterogeneity of cells on number of chromosomes, Robertsonian translocation, some line specific karyotype features were characteristic for all investigated cell populations. It was, in particular, the closest of the chromosome numbers to penta- and hexaploidies, and also the presence of translocation t(6;12). The possible connections between revealing karyotype traits and the mechanisms of maintenance of cell polypotency and proliferation in cultural condition were discussed.</p></abstract><trans-abstract xml:lang="ru"><p>Выполнен сравнительный анализ цитогенетических характеристик в популяциях клеток разных пассажей эмбриональной герминативной клеточной линии G1, полученной из полового бугорка 12,5-дневного эмбриона мыши линии BALB/c. Обнаружено, что несмотря на выраженную гетерогенность клеток по числу хромосом, робертсоновским транслокациям, для них характерны некоторые линейноспецифические черты кариотипа, в частности, близость числа хромосом к пента- и гексаплоидным наборам, а также присутствие транслокации t(6;12). Обсуждается возможность связи выявленных кариотипических особенностей с линеноспецифическими механизмами поддержания полипотентности и пролиферации эмбриональных герминативных клеток в культуральных условиях.</p></trans-abstract><kwd-group xml:lang="en"><kwd>embryonic germ cell</kwd><kwd>Robertsonian translocation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эмбриональные герминативные клетки</kwd><kwd>робертсоновская транслокация</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was partially funded by the Ministry of Education and Science of Ukraine (№ F18/11- 2006).</funding-statement><funding-statement xml:lang="ru">Работа выполнена при частичном финансировании Министерства образования и науки Украины (№ Ф18/11- 2006).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Park J.H., Kim S.J., Lee J.B. et al.
