We evaluated and compared the ability of the UDPHAp as a three-dimensional (3D) bone tissue engineering scaffold to the interconnected calcium porous HAp ceramic (IP-CHA). To achieve this, we evaluated in vitro the compressive strength, controlled rhBMP-2 release behavior, adherent cell morphology, cell adhesion manner, and cell attachment of UDPHAp. As a further in vivo experiment, UDPHAp and IP-CHA with rhBMP-2 were transplanted into mouse calvarial defects to evaluate their bone-forming ability. The Results demonstrated that the maximum compressive strengths of the UDPHAp was 7.89 +/- 1.23 MPa and higher than that of IP-CHA (1.92 +/- 0.53 MPa) (p = 0.0039). However, the breaking energies were similar (8.99 +/- 2.72 vs. 13.95 +/- 5.69 mJ, p = 0.055). The UDPHAp released rhBMP-2 more gradually in vivo. Cells on the UDPHAp adhered tightly to the surface, which had grown deeply into the scaffolds. A significant increase in cell number on the UDPHAp was observed compared to the IP-CHA on day 8 (102,479 +/- 34,391 vs. 32,372 +/- 29,061 estimated cells per scaffold, p = 0.0495). In a mouse calvarial defect model, the percentages of new bone area (mature bone + trabecular bone) in the 2x field were 2.514% +/- 1.224% for the IP-CHA group and 7.045% +/- 2.055% for the UDPHAp group, and the percentage was significantly higher in the UDPHAp group (p = 0.0209). While maintaining the same strength as the IP-CHA, the UDPHAp with 84% porosity showed a high cell number, high cell invasiveness, and excellent bone formation. We believe the UDPHAp is an excellent material that can be applied to bone regenerative medicine."}]}, "item_1627890986942": {"attribute_name": "出版タイプ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_be7fb7dd8ff6fe43", "subitem_version_type": "NA"}]}, "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": "田中, 学", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "103725", "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": "2017-06-06"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "13MH029A_shinsa.pdf", "filesize": [{"value": "107.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 107900.0, "url": {"label": "内容の要旨", "url": "https://soar-ir.repo.nii.ac.jp/record/18991/files/13MH029A_shinsa.pdf"}, "version_id": "a525d219-e21e-41f2-905d-1f4f087a41f7"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-06-06"}], "displaytype": "detail", "download_preview_message": "", "file_order": 1, "filename": "13MH029A_yoshi.pdf", "filesize": [{"value": "129.0 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 129000.0, "url": {"label": "審査結果の要旨", "url": "https://soar-ir.repo.nii.ac.jp/record/18991/files/13MH029A_yoshi.pdf"}, "version_id": "8e5a965a-4c8a-4814-b9fa-0f2e0b73edef"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-06-06"}], "displaytype": "detail", "download_preview_message": "", "file_order": 2, "filename": "13MH029A_ronbun.pdf", "filesize": [{"value": "7.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensefree": "© 2017 by the authors; licensee MDPI, Basel, Switzerland.
