Среди многообразия применяемых методик определенными преимуществами обладают молекулярногенетические методы исследований, базирующиеся на анализе высокополиморфных участков ДНК – коротких тандемных повторов (short tandem repeats, STR). Однако данный подход, несмотря на высокую информативность, обладает ограниченной чувствительностью. В этой связи представляется целесообразным внедрение более чувствительных диагностических решений, в частности, анализа InDelполиморфизма, с последующим выявлением продуктов ПЦР в режиме реального времени. При анализе ряда маркеров были получены данные, свидетельствующие о более высокой чувствительности данного метода, однако наличие отклонений в оценке соотношений клеток в интервале от 10 до 90 % указывает на целесообразность использования данного подхода лишь при оценке остаточной популяции клеток реципиента.</p></abstract><trans-abstract xml:lang="en"><p>Reduction of minimal residual disease to undetectable levels is the key criterion for efficiency of allogeneic hematopoietic stem cell transplantation (alloHSCT), along with engraftment of transplanted cells with complete replacement of recipient hematopoiesis, i. e., full posttransplant chimerism. Among different approaches, molecular genetic techniques are preferable, being based on the analysis of highly polymorphic DNA sequences (short tandem repeats, STRs). However, this approach, despite its high specificity, has a limited sensitivity. In this regard, it seems appropriate to introduce more sensitive diagnostic solutions, in particular, analysis of insertion/deletion (InDel) polymorphisms, followed by real-time detection of PCR products. The data obtained upon analysis of several genetic markers have shown higher sensitivity of this method. However, the deviations in the range of 10 to 90 % in evaluation of the cell ratios indicates the feasibility of using this approach just to evaluate the residual populations of recipient cells.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>химеризм</kwd><kwd>аллогенная трансплантация гемопоэтических стволовых клеток</kwd><kwd>микросателитные повторы</kwd><kwd>InDel полиморфизмы</kwd><kwd>STRлокусы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chimerism</kwd><kwd>allogeneic hematopoietic stem cell transplantation</kwd><kwd>INDEL polymorphisms</kwd><kwd>STR markers</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Российский Фонд Фундаментальных Исследований (проект №16-54-00198)</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">Alizadeh M., Bernard M., Danic B. et al.
