Here, we show that the phenotype of transdifferentiated hepatocytes can be reversed by modulating culture conditions. Spheroidal aggregates of hepatocytes were cultured within a collagen gel matrix in the presence of serum and tumor necrosis factor-α. Spheroids transformed into ductular structures composed of small cuboidal cells, lost the expression of hepatocytic markers, whereas aberrantly expressed bile ductular markers. The transdifferentiated cells were then retrieved from the gels, plated on surfaces coated with a basement membrane-like material, and cultured in serum-free media. Cells spontaneously formed spheroidal aggregates and recovered hepatocytic phenotype. Dexamethasone (Dex), which suppressed the phosphorylation of ERK and Jun N-terminal kinase, facilitated the recovery, and the combination with interleukin-6 or oncostatin M resulted in the recovery of hepatocyte nuclear factor 4 α protein expression and the typical hepatocytic morphology, and a decrease in the expression of bile ductular markers. A cDNA microarray analysis revealed that the hepatocyte-specific mRNA expression profile was recovered in these cells. Our results demonstrate that hepatocytes are able to recover their phenotypes following bile ductular transdifferentiation, suggesting that hepatocytic and bile ductular phenotypes may be mutually reversible.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_5_description_36":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"Author","subitem_description_type":"Other"}]},"item_5_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_5_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_5_relation_24":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.ajpath.2012.08.034","subitem_relation_type_select":"DOI"}}]},"item_5_source_id_22":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0002-9440","subitem_source_identifier_type":"PISSN"}]},"item_5_text_44":{"attribute_name":"ID(XooNIps)","attribute_value_mlt":[{"subitem_text_value":"23041063"}]},"item_5_text_54":{"attribute_name":"閲覧数(XooNIps)","attribute_value_mlt":[{"subitem_text_value":"890"}]},"item_5_text_55":{"attribute_name":"ダウンロード数(XooNIps)","attribute_value_mlt":[{"subitem_text_value":"1037"}]},"item_5_version_type_38":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sone, Masayuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13234","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishikawa, Yuji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13235","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nagahama, Yasuharu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13236","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kumagai, Eriko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13237","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Doi, Yuko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13238","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Omori, Yasufumi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13239","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshioka, Toshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13240","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tokairin, Takuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13241","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshida, Masayuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13242","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sugiyama, Toshihiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13243","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Enomoto, Katsuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13244","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-07-06"}],"displaytype":"detail","filename":"5016.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"5016.pdf","url":"https://asahikawa-med.repo.nii.ac.jp/record/4274/files/5016.pdf"},"version_id":"e6d9c9d4-22fb-4835-81a6-ec6eea6d54bb"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Recovery of mature hepatocytic phenotype following bile ductular transdifferentiation of rat hepatocytes in vitro","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Recovery of mature hepatocytic phenotype following bile ductular transdifferentiation of rat hepatocytes in vitro","subitem_title_language":"en"}]},"item_type_id":"5","owner":"3","path":["6","7","24"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-02-04"},"publish_date":"2013-02-04","publish_status":"0","recid":"4274","relation_version_is_last":true,"title":["Recovery of mature hepatocytic phenotype following bile ductular transdifferentiation of rat hepatocytes in vitro"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2024-07-26T08:36:34.926387+00:00"}
