Under these circumstances, it is indispensable to develop the imaging technologies and methodologies for noninvasive visualization of 3D cells fabricated. The objective of this study is to develop the labeling method of human induced pluripotent stem (iPS) cells-derived 3D cartilage tissue with gelatin nanospheres coincorporating three kinds of quantum dots (QD) and iron oxide nanoparticles (IONP) (GNSQD+IONP). In this study, two labeling methods were performed. One is that a cartilage tissue was labeled directly by incubating with octaarginine (R8)-treated GNSQD+IONP (direct labeling method). The other one is a \"dissociation and labeling method.\" First, the cartilage tissue was dissociated to cells in a single dispersed state. Then, the cells were incubated with R8-GNSQD+IONP in a monolayer culture. Finally, the cells labeled were fabricated to 3D pellets or cell sheets. By the direct labeling method, only cells residing in the surrounding site of cartilage tissue were labeled. On the contrary, the 3D cartilage pellets and the cell sheets were homogenously labeled and maintained fluorescently visualized over 4 weeks. In addition, the cartilage properties were histologically detected even after the process of dissociation and labeling. Homogenous labeling and visualization of human iPS cells-derived 3D cartilage tissue was achieved by the dissociation and labeling method with GNSQD+IONP. Impact statement The homogenous labeling and visualization of human iPS cells-derived three-dimensional (3D) cartilage tissue was achieved over 4 weeks by the dissociation and labeling method with gelatin nanospheres coincorporating quantum dots (QD) and iron oxide nanoparticles (IONP) (GNSQD+IONP). The cartilage properties of cells treated were maintained. It is concluded that the dissociation and labeling method with GNSQD+IONP is a promising to visualize the human iPS cells-derived 3D cartilage tissue.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Mary Ann Liebert"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1089/ten.TEC.2020.0029","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://pubmed.ncbi.nlm.nih.gov/32143549/","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1937-3384","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Murata, Yuki"}],"nameIdentifiers":[{"nameIdentifier":"1013346","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jun-Ichiro, Jo"}],"nameIdentifiers":[{"nameIdentifier":"1013347","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiroshi, Yukawa"}],"nameIdentifiers":[{"nameIdentifier":"1013348","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsumaki, Noriyuki"}],"nameIdentifiers":[{"nameIdentifier":"1013349","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshinobu, Baba"}],"nameIdentifiers":[{"nameIdentifier":"1013350","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tabata, Yasuhiko"}],"nameIdentifiers":[{"nameIdentifier":"1013351","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiroshi, Yukawa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1013352","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshinobu, Baba","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1013353","nameIdentifierScheme":"WEKO"}]}]},"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":"Visualization of human induced pluripotent stem cells-derived three-dimensional cartilage tissue by gelatin nanospheres","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Visualization of human induced pluripotent stem cells-derived three-dimensional cartilage tissue by gelatin nanospheres"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-04-08"},"publish_date":"2021-04-08","publish_status":"0","recid":"82669","relation_version_is_last":true,"title":["Visualization of human induced pluripotent stem cells-derived three-dimensional cartilage tissue by gelatin nanospheres"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:52:47.505154+00:00"}
