This study was conducted to optimize the cultural environment. \nMethods: We used 35 blastocysts that had been discarded after in-vitro fertilization. The concordance rate of karyotype analysis results between whole embryos (WEs), spent culture mediums (SCMs), and trophectoderms after 8, 16, and 24h of culture was examined. Next, zona pellucida (ZP)-free blastocysts and then early blastocysts were cultured for 24h each.\nResults: Regarding the optimal culture times, the concordance rate between WEs and SCMs was 20%, 60%, and 100% at 8, 16, and 24h, respectively. Significant differences were found between 8 and 24h. The concordance rate with ZP cultures was 40.0%, and no significant differences were found. The concordance rate of early blastocysts thawed and cultured for 24h was 40.0%, which was significantly lower than that of day 5 blastocysts.\nConclusions: The optimal culture times for niPGT-A were 24h, and the concordance rate with free ZP was higher. The concordance rate for early blastocysts was low, suggesting that optimization of the conditions may be necessary.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_7_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本文/Department of Obstetrics and Gynecology, Graduate School of Medicine, Mie University, 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":"甲医学第2295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":"10.1002/rmb2.12604","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_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Doctoral Dissertation / 博士論文"}]},"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":"森下, みどり","creatorNameLang":"ja"},{"creatorName":"モリシタ, ミドリ","creatorNameLang":"ja-Kana"},{"creatorName":"Morishita, Midori","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2025-04-25"}],"filename":"2024DM1204.pdf","filesize":[{"value":"1.21 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"2024DM1204.pdf","objectType":"fulltext","url":"https://mie-u.repo.nii.ac.jp/record/2001424/files/2024DM1204.pdf"},"version_id":"d5cb33a7-2168-40a9-9477-70e32672926a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"blastocyst","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"embryo","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"niPGT-A","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"PGT-A","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"zona pellucida","subitem_subject_language":"en","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":"Conditions for improved accuracy of noninvasive preimplantation genetic testing for aneuploidy: Focusing on the zona pellucida and early blastocysts","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Conditions for improved accuracy of noninvasive preimplantation genetic testing for aneuploidy: Focusing on the zona pellucida and early blastocysts","subitem_title_language":"en"}]},"item_type_id":"7","owner":"15","path":["1721969789237"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-04-25"},"publish_date":"2025-04-25","publish_status":"0","recid":"2001424","relation_version_is_last":true,"title":["Conditions for improved accuracy of noninvasive preimplantation genetic testing for aneuploidy: Focusing on the zona pellucida and early blastocysts"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2025-04-25T04:30:40.103561+00:00"}
