However there are limitations to the supply of human liver from surgical resection. Therefore, the efficient use of a limited liver supply is required. For the purpose it is extremely important to establish efficient techniques for the cell isolation and cold-preservation of isolated liver cells. As for the isolation of hepatocytes from surgically removed pig livers, dispase perfusion followed by collagenase digestion should yield hepatocytes with more than 90% viability. Cold-preservation for eight hours using isolated pig hepatocytes in the following preservation media was compared ; 1) University of Wiconsin (UW) solution with ascorbic acid 2 glucocide (AA2G) 2) University of Wisconsin (UW) solution 3) 100% fetal bovine serum 4) Dulbecco's Modified Eagle's Medium supplemented with 10% fetal bovine serum With the UW solution, viability, plating efficiency and ammonium clearance were well preserved after eight hours of cold-preervation. UW + AA2G solution yielded the best preservation effect. The use of AA2G inhibited activation of caspase-3, resulting in well-preserved cellular ATP levels. Based on the above results, the UW + AA2G solution appeared to be most suitable for cold-preservation of pig hepatocytes. Clininal application for the cold-preservation of human hepatocytes can be expected."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"武居, 道彦","creatorNameLang":"ja"},{"creatorName":"タケスエ, ミチヒコ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKESUE, Michihiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-01-23"}],"displaytype":"detail","filename":"KJ00001725526.pdf","filesize":[{"value":"982.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00001725526.pdf","objectType":"fulltext","url":"https://kwmed.repo.nii.ac.jp/record/1267/files/KJ00001725526.pdf"},"version_id":"958c06bd-50ee-4017-a63e-2b0f63ba2d2a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Cold preservation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Isolated porcine liver cells","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ascorbic acid-2 glucocide","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"University of Wisconsin solution","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ブタ分離肝細胞の冷保存に関する基礎的検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ブタ分離肝細胞の冷保存に関する基礎的検討","subitem_title_language":"ja"},{"subitem_title":"Cold-Preservation of Primariy Isolated Pig Hepatocytes : Fundamental Study Concerning Optimal Medium","subitem_title_language":"en"}]},"item_type_id":"3","owner":"31","path":["505"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-01-23"},"publish_date":"2017-01-23","publish_status":"0","recid":"1267","relation_version_is_last":true,"title":["ブタ分離肝細胞の冷保存に関する基礎的検討"],"weko_creator_id":"31","weko_shared_id":-1},"updated":"2024-04-18T04:05:18.865370+00:00"}
