However, little is known about the molecular regulation of this process. Mesenchymal stem cells (MSCs) in the intra-muscular space are origin of ectopic fat cells in skeletal muscle. We have previously shown that high-mobility group box 2 (HMGB2), which is a nuclear protein commonly associated with mesenchymal differentiation, is involved in the early articular cartilage degeneration. In this study, we addressed the role of HMGB2 in adipogenesis of MSCs and fat infiltration into skeletal muscles. HMGB2 was highly expressed in undifferentiated MSCs and co-localized with platelet-derived growth factor receptor α (PDGFRA) known as an MSC-specific marker, while their expressions were decreased during adipocytic differentiation. Under the deficiency of HMGB2, the expressions of adipogenesis-related molecules were reduced, and adipogenic differentiation is substantially impaired in MSCs. Moreover, HMGB2+ cells were generated in the muscle belly of rat supraspinatus muscles after rotator cuff transection, and some of these cells expressed PDGFRA in intra-muscular spaces. Thus, our findings suggest that the enhance expression of HMGB2 induces the adipogenesis of MSCs and the fat infiltration into skeletal muscles through the cascade of HMGB2-PDGFRA.","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第96号"}]},"item_10006_publisher_5":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"nature"}]},"item_10006_textarea_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_textarea_value":"以下に掲載: scientificreports .2018,Volume8.Article number: 9601"}]},"item_10006_version_type_18":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"李, 徳哲"}],"nameIdentifiers":[{"nameIdentifier":"31384","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"60768175","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=60768175"}]},{"creatorNames":[{"creatorName":"Lee, Deokcheol","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"31385","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":"2020-06-21"}],"displaytype":"detail","filename":"youshi.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://miyazaki-u.repo.nii.ac.jp/record/5845.1/files/youshi.pdf"},"version_id":"f556d2a4-1b7e-497e-b29f-17bdd1e46110"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-06-21"}],"displaytype":"detail","filename":"shinsakekka.pdf","filesize":[{"value":"619.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://miyazaki-u.repo.nii.ac.jp/record/5845.1/files/shinsakekka.pdf"},"version_id":"a7801000-e847-4c97-9124-80afc0a2082c"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-06-21"}],"displaytype":"detail","filename":"honbun.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://miyazaki-u.repo.nii.ac.jp/record/5845.1/files/honbun.pdf"},"version_id":"bcf555c2-45d4-471c-9590-f8946faf1fe2"}]},"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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"HMGB2 is a novel adipogenic factor that regulates ectopic fat infiltration in skeletal muscles","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"HMGB2 is a novel adipogenic factor that regulates ectopic fat infiltration in skeletal muscles"}]},"item_type_id":"10006","owner":"2","path":["63"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-06-21"},"publish_date":"2020-06-21","publish_status":"0","recid":"5845.1","relation_version_is_last":true,"title":["HMGB2 is a novel adipogenic factor that regulates ectopic fat infiltration in skeletal muscles"],"weko_creator_id":"2","weko_shared_id":2},"updated":"2023-10-30T04:03:00.470104+00:00"}
