The submandibular glands (SMGs) of Wnt1-Cre/R26R mice have been shown positive for mesenchyme, whereas the epithelium is beta-galactosidase-negative, indicating that most mesenchymal cells are derived from cranial neural crest cells. Platelet-derived growth factor (PDGF) receptor alpha is one of the markers of neural crest-derived cells. In this study, we analyzed the roles of PDGFs and their receptors in the morphogenesis of mouse SMGs. PDGF-A was shown to be expressed in SMG epithelium, whereas PDGF-B, PDGFRalpha, and PDGFRbeta were expressed in mesenchyme. Exogenous PDGF-AA and -BB in SMG organ cultures demonstrated increased levels of branching and epithelial proliferation, although their receptors were found to be expressed in mesenchyme. In contrast, short interfering RNA for Pdgfa and -b as well as neutralizing antibodies for PDGF-AB and -BB showed decreased branching. PDGF-AA induced the expression of the fibroblast growth factor genes Fgf3 and -7, and PDGF-BB induced the expression of Fgf1, -3, -7, and -10, whereas short interfering RNA for Pdgfa and Pdgfb inhibited the expression of Fgf3, -7, and -10, indicating that PDGFs regulate Fgf gene expression in SMG mesenchyme. The PDGF receptor inhibitor AG-17 inhibited PDGF-induced branching, whereas exogenous FGF7 and -10 fully recovered. Together, these results indicate that fibroblast growth factors function downstream of PDGF signaling, which regulates Fgf expression in neural crest-derived mesenchymal cells and SMG branching morphogenesis. Thus, PDGF signaling is a possible mechanism involved in the interaction between epithelial and neural crest-derived mesenchyme.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_8_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_8_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"497","subitem_subject_scheme":"NDC"}]},"item_8_text_41":{"attribute_name":"科研費番号 ","attribute_value_mlt":[{"subitem_text_value":"21792089"}]},"item_8_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山本, 晋也","creatorNameLang":"ja"},{"creatorName":"YAMAMOTO, Shinya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"22527","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000090514729","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-27"}],"displaytype":"detail","filename":"21792089seika.pdf","filesize":[{"value":"202.8 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"21792089seika.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/4614/files/21792089seika.pdf"},"version_id":"209f2e6c-4f36-4fb7-acd5-68dda83c8ea2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"発生・分化","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"器官培養","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"マウス顎下腺","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"増殖因子","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"シグナル伝達","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"繊維芽細胞増殖因子の発現を介した血小板由来増殖因子による唾液腺形態形成の制御","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"繊維芽細胞増殖因子の発現を介した血小板由来増殖因子による唾液腺形態形成の制御","subitem_title_language":"ja"},{"subitem_title":"Platelet-derived growth factor receptor regulates salivary gland morphogenesis via fibroblast growth factor expression","subitem_title_language":"en"}]},"item_type_id":"8","owner":"18","path":["83"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-01-06"},"publish_date":"2015-01-06","publish_status":"0","recid":"4614","relation_version_is_last":true,"title":["繊維芽細胞増殖因子の発現を介した血小板由来増殖因子による唾液腺形態形成の制御"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-06-10T05:23:18.701577+00:00"}
