This study aimed to optimize 24 cryoprotectants, cooling rates, and thawing temperatures for slow freezing of spermatogonia from 25 endangered Manchurian trout (Brachymystax lenok). Whole testes were frozen with a 26 cryomedium containing 1.3 M methanol, 0.2 M trehalose, and 10% egg yolk at a cooling rate of 27 −1°C/min and then stored in liquid nitrogen for 2 days. After thawing at 30°C in a water bath, 28 testicular cells from thawed testes were intraperitoneally transplanted into allogeneic triploid 29 hatchlings. Transplanted spermatogonia migrated toward and were incorporated into recipient 30 gonads, where they underwent gametogenesis. Transplantation efficiency did not significantly 31 differ between frozen and fresh testes, demonstrating that Manchurian trout spermatogonia can be 32 successfully cryopreserved in liquid nitrogen."}]},"item_3_description_63":{"attribute_name":"研究課題番号","attribute_value_mlt":[{"subitem_description":"25114005"}]},"item_3_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_3_relation_10":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{}}]},"item_3_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.cryobiol.2016.01.004","subitem_relation_type_select":"DOI"}}]},"item_3_relation_13":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher's Version/PDF"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.cryobiol.2016.01.004","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"KAKEN研究課題: サケ科魚類の進化に伴うGSC制御機構の変化"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PLANNED-25114005/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"研究代表者: 吉崎 悟朗 (東京海洋大学) "}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://nrid.nii.ac.jp/ja/nrid/1000070281003/","subitem_relation_type_select":"URI"}}]},"item_3_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2016 Elsevier Inc..
