In anuran (frogs and toads) and urodelan (newts, axolotl, and salamanders) tailbud embryos, the median fin starts to expand along the midline. Importantly, the shape and size of the developing median fin are highly species-specific and stage-dependent, reminiscent of the fine tuning of genetic control to realize the species-specific morphology of the median fin. Here, we hypothesized that ionic composition of environmental water of the larval habitat is essential for adaptation and optimization of the developing fin morphology. Therefore, in the present study, using amphibian model organism Xenopus laevis embryos, by depleting the magnesium ions from culture saline, we reared Xenopus late-stage tailbud embryos for several days until the early larval stage, and morphometric analysis was performed to assess several parameters regarding global fin morphology and its individual epidermal cells. Magnesium-free treatment induced shortening of the early larval axial structure, and the effects on the ventral fin and its epidermal cells were significant. Based on these results, we discuss the possible mechanism that affects the fin morphology via sensing of the environmental magnesium concentration.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_3_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"原著","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_3_identifier_registration":{"attribute_name":"identifier_registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24792/0002001003","subitem_identifier_reg_type":"JaLC"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"神奈川大学総合理学研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Research Institute for Integrated Science, Kanagawa University","subitem_publisher_language":"en"}]},"item_3_source_id_10":{"attribute_name":"item_3_source_id_10","attribute_value_mlt":[{"subitem_source_identifier":"AA12068302","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"item_3_source_id_8","attribute_value_mlt":[{"subitem_source_identifier":"1880-0483","subitem_source_identifier_type":"PISSN"}]},"item_3_version_type_16":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"胡, 継楠","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"豊泉, 龍児","creatorNameLang":"ja"},{"creatorName":"トヨイズミ, リュウジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"34316","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"34316","nameIdentifierScheme":"ローカル著者ID"}]},{"creatorNames":[{"creatorName":"鈴木, 健太郎","creatorNameLang":"ja"},{"creatorName":"スズキ, ケンタロウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"34292","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"34292","nameIdentifierScheme":"ローカル著者ID"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"04 両生類アフリカツメガエル幼生の正中鰭のサイズと形状は環境水中のマグネシウム濃度に影響される.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://kanagawa-u.repo.nii.ac.jp/record/2001003/files/04 両生類アフリカツメガエル幼生の正中鰭のサイズと形状は環境水中のマグネシウム濃度に影響される.pdf"},"version_id":"4f2e7c38-9a75-4d92-a5b2-885a125a8592"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"fin morphogenesis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"epidermis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"morphometry","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"tadpole larva","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Xenopus laevis","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":"item_resource_type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"両生類アフリカツメガエル幼生の正中鰭のサイズと形状は環境水中のマグネシウム濃度に影響される","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"両生類アフリカツメガエル幼生の正中鰭のサイズと形状は環境水中のマグネシウム濃度に影響される","subitem_title_language":"ja"},{"subitem_title":"Magnesium ion concentration in environmental water is effective for the size and shape of Xenopus larval median fin","subitem_title_language":"en"}]},"item_type_id":"3","owner":"10","path":["1726789902848"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-09-20"},"publish_date":"2024-09-20","publish_status":"0","recid":"2001003","relation_version_is_last":true,"title":["両生類アフリカツメガエル幼生の正中鰭のサイズと形状は環境水中のマグネシウム濃度に影響される"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-10-09T06:30:54.798443+00:00"}
