Цель настоящего исследования заключается в изучении особенности экспрессии стромального клеточного фактора SDF-1 (stromal cell-derived factor) в гравидарном эндометрии при неразвивающейся беременности при использовании технологий экстракорпорального оплодотворения. Исследовали абортивный материал 5-8 недель при использовании технологий экстракорпорального оплодотворения с разными вариантами гравидарной трансформации. Всего исследовано 92 образца, из них 77 – абортивный материал неразвивающейся беременности после использования технологий экстракорпорального оплодотворения и 15 - образцы абортивного материала при беременности, прерванной по желанию женщины хирургическим путем. Выполнено гистологическое исследование окраской гематоксилином и эозином с описанием вариантов гравидарной трансформации стромы и желез эндометрия и иммуногистохимическое исследование фактора SDF-1 в гравидарном эндометрии обследованных групп. Исходя из гистологической картины, в зависимости от морфологического варианта гравидарной трансформации эндометрия было сформировано 5 групп случаев: полноценная гравидарная трансформация стромы и желез эндометрия и стромы с железами секреторного типа; неполноценная гравидарная трансформация стромы с железами секреторного типа, пролиферативного типа, с обоими типами и контрольная группа наблюдений. Методом морфометрии определяли площадь экспрессии маркера в гравидарном эндометрии (железах и строме). Результаты исследования показали достоверное снижение экспрессии SDF-1 в железах компактного слоя гравидарного эндометрия независимо от вариантов его трансформации после использования технологий экстракорпорального оплодотворения, что вероятно связано с нарушением синтеза хемокина SDF-1 гландулоцитами еще на этапе циклической трансформации эндометрия. Достоверное повышение экспрессии SDF-1 в строме гравидарного эндометрия обусловлено исходным нарушением морфофункционального состояния эндометрия у пациенток с бесплодием. Верификация стромального клеточного фактора в эндометрии на этапе прегравидарной подготовки позволит скорректировать подготовительный этап применения технологий экстракорпорального оплодотворения для пациенток с эндометриальной дисфункцией.</p></abstract><trans-abstract xml:lang="en"><p>The immunological factor in the genesis of reproductive losses, including the use of in vitro fertilization technologies, remains not completely clear due to the multiple pathogenetic mechanisms of immunological interactions in the mother-placenta-fetus system. The purpose of this study is to study the expression of the factor SDF-1 (stromal cell-derived factor) in the endometrium during missed miscarriage using in vitro fertilization technologies. Abortive material 5-8 weeks’ old was studied using in vitro fertilization technologies with different variants of transformation of the endometrium. A total of 92 samples were studied, of which 77 were abortive material from a missed miscarriage after the use of in vitro fertilization technologies and 15 were samples of abortive material from a pregnancy terminated surgically. A histological study was performed by staining with hematoxylin and eosin with a description of the variants of transformation of the stroma and endometrial glands and an immunohistochemical study of the SDF-1 factor in the endometrium of the examined groups. Based on the histological picture, depending on the morphological variant of the transformation of the endometrium, 5 groups of cases were formed: complete transformation of the stroma and glands of the endometrium and stroma with glands of the secretory type; incomplete transformation of the stroma with glands of the secretory type, proliferative type, with both types and the control group of observations. The expression area of ​​the marker in the endometrium (glands and stroma) was determined by morphometry. The results of the study showed a significant decrease in the expression of SDF-1 in the glands of the compact layer of the endometrium, regardless of the options for its transformation after the use of in vitro fertilization technologies, which is probably associated with a violation of the synthesis of the SDF-1 chemokine by glandulocytes at the stage of cyclic transformation of the endometrium. A significant increase in the expression of SDF-1 in the stroma of the endometrium is due to the initial violation of the its morphological and functional state in patients with infertility. Verification of stromal cell factor in the endometrium at the stage of preparation will allow to correct this stage of the application of in vitro fertilization technologies for patients with endometrial dysfunction.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эндометрий</kwd><kwd>стромальный клеточный фактор</kwd><kwd>SDF-1</kwd><kwd>неразвивающаяся беременность</kwd><kwd>экстракорпоральное оплодотворение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>endometrium</kwd><kwd>stromal cell factor</kwd><kwd>SDF-1</kwd><kwd>missed miscarriage</kwd><kwd>in vitro fertilization</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">Adamyan LV, Artymuk AV, Belokrinitskaya TE i dr.
