Investigation of molecular-cellular mechanisms of liver fibrosis can help to discover new ways of slowing down or even reverse the process of fibrogenesis in liver. For a long time hepatic stellate cells were undeservingly blamed for being the major causer of liver fibrosis, because they were considered as the main source of myofibroblasts, that synthesize connective tissue extracellular matrix. In this particular work explantation approach was used to isolate cell culture from portal tracts. It was shown that received cells are portal fibroblasts, and, just as hepatic stellate cells, in case of liver alteration can differentiate in myofibroblasts, that express а-smooth muscle actin. During long-term cultivation it was shown that portal myofibroblasts can differentiate into fibroblasts and back on late passages. So, we can conclude, that there is a potency to reverse the process of fibrogenesis in liver.</p></abstract><trans-abstract xml:lang="ru"><p>На сегодняшний день не существует эффективных способов лечения фиброза печени и единственным выходом является пересадка донорского органа. Исследование молекулярно-клеточных механизмов развития фиброза в печени может способствовать выявлению новых способов замедления, а, возможно, и обращения вспять процессов фиброгенеза в печени. Длительное время клетки Ито незаслуженно считались основными виновницами развития фиброза печени, так как рассматривались как главные предшественницы миофибробластов, которые осуществляют синтез соединительнотканного внеклеточного матрикса. В данной работе методом эксплантации была выделена культура мезенхимальных клеток, окружающих желчные протоки. Показано, что полученные клетки являются портальными фибробластами, и, как и клетки Ито, в условиях повреждения печени способны in vitro дифференцироваться в миофибробласты, экспрессирующие а-гладкомышечный актин. При длительном культивировании показана возможность «перехода» портальных миофибробластов в фибробласты и наоборот на поздних пассажах. Таким образом, можно сделать вывод о потенциальной возможности обращения вспять процессов фиброгенеза в печени.</p></trans-abstract><kwd-group xml:lang="en"><kwd>liver fibrosis</kwd><kwd>portal fibroblasts</kwd><kwd>myofibroblasts</kwd><kwd>hepatic stellate cells</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>фиброз печени</kwd><kwd>портальные фибробласты</kwd><kwd>миофибробласты</kwd><kwd>клетки Ито</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ramadori G. and Saile B.
