Furthermore, TTF-derived ntESCs showed only a very small number of point mutations, approximately 80% less than the number observed in iPSCs generated using retrovirus. Base substitution profile analysis confirmed this greatly reduced number of point mutations. The point mutations in iPSCs are therefore not a Yamanaka factor-specific phenomenon but are intrinsic to genome reprogramming. Moreover, the dramatic reduction in point mutations in ntESCs suggests that most are not essential for genome reprogramming. Our results suggest that it is feasible to reduce the point mutation frequency in iPSCs by optimizing various genome reprogramming conditions. We conducted whole genome sequencing of ntES cells derived from MEFs or TTFs. We thereby succeeded in establishing TTF-derived ntES cell lines with far fewer point\nmutations. Base substitution profile analysis of these clones also indicated a reduced point mutation frequency, moving from a transversion-predominance to a transition-predominance.","subitem_description_type":"Abstract"}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"28233378","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1002/stem.2601","subitem_relation_type_select":"DOI"}}]},"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":"Araki, Ryoko"}],"nameIdentifiers":[{"nameIdentifier":"491541","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mizutani, Eiji"}],"nameIdentifiers":[{"nameIdentifier":"491542","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hoki, Yuko"}],"nameIdentifiers":[{"nameIdentifier":"491543","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sunayama, Misato"}],"nameIdentifiers":[{"nameIdentifier":"491544","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wakayama, Sayaka"}],"nameIdentifiers":[{"nameIdentifier":"491545","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nagatomo, Hiroaki"}],"nameIdentifiers":[{"nameIdentifier":"491546","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kasama, Yasuji"}],"nameIdentifiers":[{"nameIdentifier":"491547","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakamura, Miki"}],"nameIdentifiers":[{"nameIdentifier":"491548","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wakayama, Teruhiko"}],"nameIdentifiers":[{"nameIdentifier":"491549","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Abe, Masumi"}],"nameIdentifiers":[{"nameIdentifier":"491550","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"荒木 良子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"491551","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤森 ゆう子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"491552","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"砂山 美里","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"491553","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"笠間 康次","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"491554","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中村 美樹","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"491555","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"安倍 真澄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"491556","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":"The Number of Point Mutations in Induced Pluripotent Stem Cells and Nuclear Transfer Embryonic Stem Cells Depends on the Method and Somatic Cell Type Used for Their Generation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The Number of Point Mutations in Induced Pluripotent Stem Cells and Nuclear Transfer Embryonic Stem Cells Depends on the Method and Somatic Cell Type Used for Their Generation"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-04-25"},"publish_date":"2018-04-25","publish_status":"0","recid":"48806","relation_version_is_last":true,"title":["The Number of Point Mutations in Induced Pluripotent Stem Cells and Nuclear Transfer Embryonic Stem Cells Depends on the Method and Somatic Cell Type Used for Their Generation"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:24:06.811580+00:00"}
