Macrophages are the leading regulatory cell-lineage taking part in reparative processes in mammals, and the liver is no exception. The ratio of monocyte migration, proliferation and death of macrophages during liver regeneration requires further studies. The aim was to quantify the intensity of monocyte migration, cell proliferation and apoptosis of resident liver macrophages after its 70 % resection in a mouse model. Materials and Methods. We performed 70 % liver resection in sexually mature male BalbC mice. Cells of liver monocyte-macrophage system were obtained by magnetic sorting by marker F4/80. The immunophenotype of the isolated cells was further studied by cytofluorimetry, the level of proliferation and cell death, the content of cyclins and P53 was determined by western blot. Results and Discussion . It was found that after partial hepatectomy there is a marked migration of monocytes/macrophages positive for Ly6C and CD11b markers to the liver, the migration process starts already in the first day after the operation. On the same terms there is a rise in proliferative activity of macrophages, established by Ki67 marker, the peak of proliferation - 3 days after partial hepatectomy. A significant increase in the number of dying macrophages was found early after liver resection. Conclusion . The obtained data indicate that liver regeneration in mammals on the model in mice is accompanied by proliferation migration and cell death of macrophages. Taking into account the immunophenotype of macrophages, we can conclude that Ly6C+ blood monocytes migrate to the liver, and resident macrophages participate in proliferation. The obtained data confirm the universality of the course of reparative processes in mammals.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Актуальность. Макрофаги - ведущий клеточный дифферон, принимающий участие в регуляции репаративных процессов у млекопитающих, не является исключением и печень. Соотношение миграции моноцитов, пролиферации и гибели макрофагов при регенерации печени требует дальнейших исследований. Цель исследования - количественно оценить интенсивность миграции моноцитов, клеточного размножения и апоптоза резидентных макрофагов печени после ее 70 % резекции на модели у мыши. Материалы и методы. Выполняли 70 % резекцию печени у половозрелых самцов мышей линии Balb C. Клетки моноцитарно-макрофагальной системы печени получали с помощью магнитного сортинга по маркеру F4/80. Далее изучали иммунофенотип выделенных клеток с помощью цитофлуориметрии, уровень пролиферации и клеточной гибели, содержание циклинов и Р53 определяли методом вестерн-блот. Результаты и обсуждение. Установлено, что после частичной гепатэктомии наблюдается выраженная миграция моноцитов/макрофагов положительных по маркерам Ly6C и CD11b в печень, процесс миграции начинается уже в первые сутки после операции. На этих же сроках отмечается подъем пролиферативной активности макрофагов, установленный с помощью маркера Ki67, пик пролиферации - 3 сутки после частичной гепатэктомии. В ранние сроки после резекции печени обнаружено значимое увеличение числа гибнущих макрофагов. Выводы. Полученные данные свидетельствуют о том, что регенерация печени у млекопитающих на модели у мышей сопровождается миграцией, пролиферацией и клеточной гибелью макрофагов. Учитывая иммунофенотип макрофагов, можно заключить, что в печень мигрируют Ly6C+ моноциты крови, а в пролиферации участвуют резидентные макрофаги. Полученные данные подтверждают универсальность течения репаративных процессов у млекопитающих.</p></trans-abstract><kwd-group xml:lang="en"><kwd>liver</kwd><kwd>regeneration</kwd><kwd>macrophages</kwd><kwd>migration</kwd><kwd>proliferation</kwd><kwd>apoptosis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>печень</kwd><kwd>регенерация</kwd><kwd>макрофаги</kwd><kwd>миграция</kwd><kwd>пролиферация</kwd><kwd>апоптоз</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was performed with the financial support of State assignment № 121040600436–7, and grant 22–14–00152 from the Russian Science Foundation.</funding-statement><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Государственного задания&#13;
