Here, we report production and in vitro development of cloned embryos with bovine fibroblasts taken from Japanese Black male calf and establishment of pregnancy with the cloned embryos following transfer into recipient animals. In vitro matured bovine oocytes were enucleated and used for recipient cytoplasm. Bovine cultured fibroblasts derived from ear skin of a Japanese Black male calf were used for nuclear donor. Couplets were produced by insertion of each somatic cell into perivitellin space of recipient oocytes. Total of 63％ out of 513 couplets was fused by electrostimulation. After activation treatment, the cloned embryos were cultured for 7 days. Frequencies of cleavage and development to the morula and blastocyst stages were 72％ and 19％, respectively. Ten morulae/blastocysts were transferred into recipient cattle nonsurgically respectively.  Ten morulae/blastocysts were transferred into recipient cattle nonsurgically ( 2 embryos/recipient). Ultrasoudsonographic diagnosis at 47 days after the transfer revealed that one (20％) pregnancy was established.","subitem_description_type":"Abstract"}]},"item_2_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"継続後誌:近畿大学先端技術総合研究所紀要 = Memoirs of Institute of Advanced Technology, Kinki University","subitem_description_type":"Other"}]},"item_2_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_2_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学生物理工学研究所"}]},"item_2_source_id_22":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1344414X","subitem_source_identifier_type":"ISSN"}]},"item_2_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Hosaka, T"},{"subitem_text_language":"en","subitem_text_value":"Taniguchi, S"},{"subitem_text_language":"en","subitem_text_value":"Saeki, K"},{"subitem_text_language":"en","subitem_text_value":"Kaneko, T"},{"subitem_text_language":"en","subitem_text_value":"Matsumoto, K"},{"subitem_text_language":"en","subitem_text_value":"Hosoi, Y"},{"subitem_text_language":"en","subitem_text_value":"Nishimoto, Y"},{"subitem_text_language":"en","subitem_text_value":"Iritani , A"}]},"item_2_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学生物理工学部"},{"subitem_text_value":"和歌山県畜産試験場"},{"subitem_text_value":"近畿大学生物理工学研究所 , 近畿大学生物理工学部"},{"subitem_text_value":"近畿大学生物理工学部"},{"subitem_text_value":"近畿大学生物理工学研究所 , 近畿大学生物理工学部"},{"subitem_text_value":"近畿大学生物理工学研究所 , 近畿大学生物理工学部"},{"subitem_text_value":"和歌山県畜産試験場"},{"subitem_text_value":"近畿大学生物理工学研究所 , 近畿大学生物理工学部"}]},"item_2_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Department of Genetic Engineering, Kinki University"},{"subitem_text_value":"Wakayama Prefecture Livestock Experimental Station"},{"subitem_text_value":"Resaerch Institute of Biology-Oriented Science and Technology , Department of Genetic Engineering, Kinki University"},{"subitem_text_value":"Resaerch Institute of Biology-Oriented Science and Technology , Department of Genetic Engineering, Kinki University"},{"subitem_text_value":"Wakayama Prefecture Livestock Experimental Station"},{"subitem_text_value":"Resaerch Institute of Biology-Oriented Science and Technology , Department of Genetic Engineering, Kinki University"}]},"item_2_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"保坂,  卓"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"谷口,  俊仁"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐伯,  和弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"金子,  武人"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松本,  和也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"細井,  美彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"西本,  尚武"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"入谷,  明"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-18"}],"displaytype":"detail","filename":"AA11312113-20000112-0045.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA11312113-20000112-0045.pdf","url":"https://kindai.repo.nii.ac.jp/record/10088/files/AA11312113-20000112-0045.pdf"},"version_id":"8416fc46-8074-4e43-a9ad-aedd59425e22"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"子ウシ線維芽細胞を用いた核移植によるクローンウシの受胎","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"子ウシ線維芽細胞を用いた核移植によるクローンウシの受胎"}]},"item_type_id":"2","owner":"3","path":["2255","3448"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-07-13"},"publish_date":"2010-07-13","publish_status":"0","recid":"10088","relation_version_is_last":true,"title":["子ウシ線維芽細胞を用いた核移植によるクローンウシの受胎"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T23:47:16.513543+00:00"}
