Доказано, что пролиферативная активность МСК из децидуальной оболочки и ворсин хориона не отличается и позволяет в течение 3 мес. увеличить первоначальное количество клеток в 1010 раза, что в 104 раза выше, чем МСК из амниона. Содержание колониеобразующих единиц фибробластов (КОЕ-Ф) в хорионе и децидуальной оболочке сопоставимо и достоверно выше, чем в амнионе, но не отличается от КОЕ-Ф в костном мозге. Кумулятивное популяционное удвоение МСК плаценты на всех пассажах достоверно выше, чем МСК костного мозга. Децидуальная оболочка и хорион плаценты – идеальные источники для экспансии МСК, которые в дальнейшем могут быть зарезервированы в банке клеток и использованы в клеточной терапии, особенно при требовании высоких доз МСК.</p></abstract><trans-abstract xml:lang="en"><p>The ability of mesenchymal stem cells (MSCs) isolated from the decidua, chorionic tissue and amniotic membrane of the placenta to the self-renewal and the proliferation was investigated. Our results revealed that the number of colony forming unit-fibroblast (CFU-F) and the growth rate of MSCs were higher in the decidua and chorionic tissue compared to the amniotic membrane. Decidua MSCs and chorionic MSCs possessed a similar powerful proliferative potential and increased in 1010- fold in cultures for 3 months, that is 103 times more then the amniotic MSCs. The cumulative population doubling (PD) of placenta-derived MSCs was significantly higher at all passages then PD of bone marrow derived MSCs. The decidua and chorionic tissue of the placenta are ideal MSCs sources for cell based therapy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мезенхимальные стволовые клетки</kwd><kwd>плацента</kwd><kwd>децидуальная оболочка</kwd><kwd>хорион</kwd><kwd>амнион</kwd><kwd>КОЕ-Ф</kwd><kwd>популяционное удвоение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mesenchymal stem cells</kwd><kwd>placenta</kwd><kwd>deciduas</kwd><kwd>chorionic tissue</kwd><kwd>amniotic membrane</kwd><kwd>CFU-F</kwd><kwd>population doubling</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">Bianco P.
