The aim of our research was to study the role of pancreatic stellate cells in pancreas regeneration in the above mentioned model. 24 male Wistar rats were fed a copper-deficient diet, containing triethylenetetramine tetrahydrochloride, for a period of 8 weeks, then animals were returned to the normal rat chow for up to a period of 8 weeks. Animals were killed at the end of 4, 6, 8 weeks of copper-deficient diet and 4, 6, 8 weeks after they were returned to normal diet. Paraffin-embedded sections of pancreas were stained immunohistochemically with antibodies to desmin, the pancreatic stellate cells marker. The acinar tissue structure destruction was observed starting from the period of 4 weeks of copper-deficient diet. Partial acinar restoration was observed 6 and 8 weeks after rats were returned to the normal balanced rat chaw. An increase in the number of desmin-positive stellate cells both in pancreatic acinar tissue and in islets was observed at all periods of experiment. Along with the partial acinar tissue recovery desmin-positive cells were found mainly in areas of newly formed pancreatic tissue.</p></abstract><trans-abstract xml:lang="ru"><p>В ряде исследований была продемонстрирована возможность трансдифференцировки клеток поджелудочной железы в гепатоцитоподобные клетки в модели «истощения-пресыщения медью» у крыс. Предполагается, что звездчатые клетки поджелудочной железы могут быть ее региональными стволовыми клетками, а также способны при определенных условиях образовывать гепатоциты и холангиоциты. Целью исследования стало изучение роли звездчатых клеток поджелудочной железы в её регенерации в данной модели. Эксперименты проведены на 24 белых лабораторных крысах-самцах линии Вистар весом 80-100 г. Животные получали медь-дефицитную диету с добавлением триэти-лентетрамина тетрагидрохлорида в течение 8 нед., затем были переведены на сбалансированный корм для грызунов в течение 8 нед. Животные выведены из эксперимента на сроках 4, 6, 8 нед. кормления и 4, 6, 8 нед. отмены медь-дефицитной диеты. Гистологические срезы поджелудочной железы окрашивали иммуногистохимическим методом с использованием антител против маркера звездчатых клеток поджелудочной железы - десмина. Нарушение структуры ацинарной ткани наблюдали, начиная со срока 4 недели кормления медь-дефицитной диетой. Частичное восстановление ацинусов происходило на сроках 6 и 8 нед. после перехода на сбалансированное питание. На всех сроках эксперимента наблюдали увеличение количества десмин-позитивных звездчатых клеток. На фоне частичного восстановления ацинарной ткани десмин-пози-тивные клетки располагались преимущественно в участках вновь образующейся ткани поджелудочной железы.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pancreas</kwd><kwd>pancreatic stellate cells</kwd><kwd>regeneration</kwd><kwd>copper-deficient diet</kwd><kwd>desmin</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>поджелудочная железа</kwd><kwd>звёздчатые клетки поджелудочной железы</kwd><kwd>регенерация</kwd><kwd>медь-дефицитная диета</kwd><kwd>десмин</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Shen C.-N., Horb M.E., Slack J.M.W. et al.
