Согласно общепринятым представлениям, сердце человека имеет ограниченный регенеративный потенциал, но исследования последних лет показывают, что функционально значимая регенерация возможна. Однако механизмы, лежащие в основе данных процессов, остаются малоизученными. В сердце встречаются популяции резидентных мезенхимных клеток, обладающих некоторыми свойствами стволовых клеток, несущих определенные маркеры, такие как c-kit+, Sca-1 и другие. Способность данных клеток дифференцироваться напрямую в кардиомиоциты остаётся спорным вопросом, но их использование в клинических испытаниях показало улучшение сердечной функции у пациентов, перенесших инфаркт миокарда. В настоящее время разрабатываются подходы по использованию, в основном, индуцированных плюрипотентных стволовых клеток в качестве перспективной восстановительной терапии, но кардиопротективная роль мезенхимных клеток сердца остаётся предметом активного изучения, благодаря их паракринной сигнализации.</p></abstract><trans-abstract xml:lang="en"><p>The search and study of endogenous heart repair remains an urgent issue in modern regenerative medicine. It is generally accepted that the human heart has a limited regenerative potential, but recent studies show that functionally significant regeneration is possible. However, the mechanisms underlying these processes remain poorly understood. In the heart, there are populations of resident mesenchymal cells that have some properties of stem cells that carry certain markers, such as c-kit+, Sca-1, etc. The ability of these cells to differentiate directly into cardiomyocytes remains controversial, but their use in clinical trials has shown improved cardiac function in patients with myocardial infarction. Currently, approaches are being developed to use, mainly, induced pluripotent stem cells as a promising regenerative therapy, but the cardioprotective role of cardiac mesenchymal cells remains the subject of active study due to their paracrine signaling.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>клеточная терапия</kwd><kwd>регенерация миокарда</kwd><kwd>мезенхимные клетки сердца</kwd><kwd>инфаркт миокарда</kwd><kwd>кардиомиопатии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cell therapy</kwd><kwd>myocardial regeneration</kwd><kwd>cardiac mesenchymal cells</kwd><kwd>myocardial infarction</kwd><kwd>cardiomyopathies</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке гранта РФФИ № 20-015-00574.</funding-statement><funding-statement xml:lang="en">The research was financially supported by the RFBR grant № 20-015-00574.</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">Благова О.
