Methods: The rat sciatic nerves were crushed with an aneurysm clip resulting in axonal degeneration. In the normal nerve, and at 1, 2, 4, and 8 weeks after injury, BMP-7, BMP receptors, p-Smad 1/5/8, and Noggin, the endogenous BMP antagonist, were evaluated. Additionally, the distribution of BMP-7 was assessed by fluorescent double immunostaining. In vitro studies were also performed to examine the effect of BMP-7 and PTH (1-34) administration on rat Schwann cells (SCs). Results: Aneurysm clip made reliable animal model\nof the nerve injury with recovery at 8 weeks after the injury. BMP-7/Smad protein and mRNA were significantly upregulated on axon-SCs units at 1 week after injury, and this upregulated expression was maintained for 4 weeks. Besides, significant upregulation of Noggin’s expression was observed on axon-SCs units at 2 weeks after injury.Moreover, fluorescent double immunostaining showed co-localization between expression of BMP-7 and p75NTR during axonal regeneration. In the in vitro study, administration of BMP-7 induced significant proliferation of SCs. Application of PTH (1-34) upregulated BMP-7 on SCs. Discussion/conclusion: BMPs were reported to be involved in protection and recovery after injury as well as in neurogenesis. Our current study showed that BMP/Smad signaling molecules were upregulated on dedifferentiated SCs after peripheral nerve injury and that administration of BMP-7 increased SC viability in vitro. These results suggested that axonal regeneration could be induced via upregulation of endogenous BMP-7 on SCs by PTH (1-34) administration.","subitem_description_type":"Abstract"}]},"item_7_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本文/Department of Orthopaedic Surgery, Mie University Graduate School of Medicine, Tsu, Japan","subitem_description_type":"Other"},{"subitem_description":"10p","subitem_description_type":"Other"}]},"item_7_dissertation_number_60":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"乙医学第1030号"}]},"item_7_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_7_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1177/2309499018812953","subitem_relation_type_select":"DOI"}}]},"item_7_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_7_text_63":{"attribute_name":"ノート","attribute_value_mlt":[{"subitem_text_value":"Journal of Orthopaedic Surgery 26(3) 1–10に掲載"}]},"item_7_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Doctoral Dissertation / 博士論文"}]},"item_7_version_type_15":{"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":"Kokubu, Naoki","creatorNameLang":"en"},{"creatorName":"コクブ, ナオキ","creatorNameLang":"ja-Kana"},{"creatorName":"國分, 直樹","creatorNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-10-16"}],"displaytype":"detail","filename":"2018DM0352.pdf","filesize":[{"value":"3.0 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"2018DM0352.pdf","objectType":"fulltext","url":"https://mie-u.repo.nii.ac.jp/record/12793/files/2018DM0352.pdf"},"version_id":"eaf8bbc7-2eef-4e1b-a49d-de6dc36e0416"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"bone morphogenetic protein-7","subitem_subject_scheme":"Other"},{"subitem_subject":"Noggin","subitem_subject_scheme":"Other"},{"subitem_subject":"parathyroid hormone (PTH) (1-34)","subitem_subject_scheme":"Other"},{"subitem_subject":"peripheral nerve regeneration","subitem_subject_scheme":"Other"},{"subitem_subject":"Schwann cells","subitem_subject_scheme":"Other"}]},"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":"BMP-7/Smad expression in dedifferentiated Schwann cells during axonal regeneration and upregulation of endogenous BMP-7 following administration of PTH (1-34)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"BMP-7/Smad expression in dedifferentiated Schwann cells during axonal regeneration and upregulation of endogenous BMP-7 following administration of PTH (1-34)","subitem_title_language":"en"}]},"item_type_id":"7","owner":"16","path":["915"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2019-10-16"},"publish_date":"2019-10-16","publish_status":"0","recid":"12793","relation_version_is_last":true,"title":["BMP-7/Smad expression in dedifferentiated Schwann cells during axonal regeneration and upregulation of endogenous BMP-7 following administration of PTH (1-34)"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2023-10-31T06:02:33.155662+00:00"}
