In this study, we established the method for evaluating the response of peritoneal xenografts to chemotherapy of metastatic gastric cancer using intravital TPLSM.\nMethods Red fluorescent protein-expressing gastric cancer cells (NUGC4) were inoculated into the peritoneal cavity of green fluorescent protein nude mice.\nResults Laparotomy revealed that 2 weeks after inoculation, macroscopic peritoneal metastatic nodules were formed. The first intravital TPLSM session revealed that they were composed of red tumor cell clusters and green surrounding stroma. Paclitaxel was administered intraperitoneally after the first TPLSM three times a week for 7 days in the treatment group. At the second laparotomy, there were significantly fewer and smaller nodules in the treated mice than in the controls. The second intravital TPLSM session showed tumor cell fragmentation, swelling, and nuclear condensation in the metastatic nodules—a response to chemotherapy. There were multinuclear tumor cells in the paclitaxel-treated living mice.\nConclusions Our method may become a powerful tool for evaluating the efficacy of novel anti-gastric cancer drugs in a preclinical murine model with minimum interindividual variation.","subitem_description_type":"Abstract"}]},"item_7_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本文/Department of Gastrointestinal and Pediatric Surgery, Mie University Graduate School of Medicine, 2-174 Edobashi, Tsu, Mie 514-8507, 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":"甲医学第1654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":"10.1007/s10120-013-0334-y","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":"Gastric Cancer. 2015 Jan;18(1):109-18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":"Shimura, Tadanobu","creatorNameLang":"en"},{"creatorName":"シムラ, タダノブ","creatorNameLang":"ja-Kana"},{"creatorName":"志村, 匡信","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":"2021-12-09"}],"displaytype":"detail","filename":"2013DM020.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"2013DM020","objectType":"fulltext","url":"https://mie-u.repo.nii.ac.jp/record/14411/files/2013DM020.pdf"},"version_id":"468e6003-788f-4634-a5f4-656d96307179"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Paclitaxel","subitem_subject_scheme":"Other"},{"subitem_subject":"Peritoneal metastatic xenograft","subitem_subject_scheme":"Other"},{"subitem_subject":"Gastric cancer","subitem_subject_scheme":"Other"},{"subitem_subject":"Two-photon laser scanning microscopy","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":"In vivo optical pathology of paclitaxel efficacy on the peritoneal metastatic xenograft model of gastric cancer using two-photon laser scanning microscopy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"In vivo optical pathology of paclitaxel efficacy on the peritoneal metastatic xenograft model of gastric cancer using two-photon laser scanning microscopy","subitem_title_language":"en"}]},"item_type_id":"7","owner":"16","path":["620"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-12-09"},"publish_date":"2021-12-09","publish_status":"0","recid":"14411","relation_version_is_last":true,"title":["In vivo optical pathology of paclitaxel efficacy on the peritoneal metastatic xenograft model of gastric cancer using two-photon laser scanning microscopy"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2023-11-08T05:55:07.292457+00:00"}
