The epidermis is not well endowed with mucous or granular cells. In the postflexion larval stage, 10 day old, 5.4 mm in total length (TL), the epidermal filament-containing cells are flattened cells in a single stratum and have a large number of the cell organelles such as mitochondria, well-developed Golgi apparatus, highly convoluted lamellar endoplasmic reticula. Intraepithelial blood capillaries which may be used during air-breathing organ respiration, were also observed. Type I cells of surface epidermis are flat forming in a single stratum. The outermost layer is composed of a free surface of Type I cells with numerous microridges. The middle layer contains several strata of Type II cells. The rather unique thick, special corky structure of Type II cells is thought to play an important role in thermal insulation and protection against ultraviolet light for existence out of water. The basal layer comprises of a stratum of filament-containing cells, generally long and either ovoid or spindle shaped. Differentiation in the surface layer of the epidermis occurred at 30 day old, 11.4 mm TL. In the benthic larval stage, 46 day old, 17.5 mm TL, the Type II cells are characterized by having an large vacuole in the cytoplasm. This vacuole enlarges by the fusion of plasma membranes of adjacent cells and a considerable number of dense, fibrous bodies aggregate around the lamellated cisternae of endoplasmic reticula. These observation suggest that differentiation of the epidermis of Periophthalmus modestus seem to be occur just before migration to the terrestial habit.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"トビハゼ浮遊期仔魚の表皮の微細構造を発育段階を追って電子顕微鏡を用いて観察することにより,本種の特異的皮膚構造の分化と発達過程を生態的適応の観点から追究した。後屈曲期が表皮の階層構造分化の開始期で,内湾の河口域に接岸回遊して陸上生活に移行する直前までの底生生活移行期に3層の階層分化が完了すると考えられた。表層細胞と中層細胞はいずれも基底細胞から分化するものと考えられ,その分化過程は次のように推定された。表皮最内層には未分化の基底線維芽細胞が位置し,これが増殖を繰り返しながら一部は基底細胞として留まるものの,その他多くは上層へ移動して表層域にまで達する。表層域にまで達した基底細胞は,細胞の最外縁の自由表面に微小堤を発達させながらその部分を肥厚させ,偏平単層の表皮細胞(Type I cell)に分化する。また,基底細胞のなかには後屈曲期に形成したアコーデオン型層板状単位膜構造を保有したまま表層域に到達し,そこで単位膜の周囲に遊離のリボゾームを集合させる。そして,滑面小胞体から粗面小胞体の膜構造に変化しつつ再び下方へと移動しながら指状嵌合を発達させて単位膜間の間隔を広げ,細胞質が中空の中層細胞(Type II cell)に分化する。加えて,本種は仔魚期の表皮内毛細血管網をそのまま残存させて陸上生活のみならず,水中生活においても機能させていると考えられる。これらのことから,皮膚の生態的適応から推定してトビハゼは,皮膚の分化や発生調整のメカニズムを通じて、皮膚呼吸には不都合な表皮の厚い角質化という分化能を発達させず,幼期の皮膚呼吸に合目的な皮膚血管構造を保持しながら,表皮細胞の中空化による階層分化を獲得して,干潟という湿地帯での両棲的生活に適応しているものと解釈された。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"南西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Nansei National Fisheries Research Instituite","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nnf_k_28_33","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010510442","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00181988","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0388-841X","subitem_source_identifier_type":"PISSN"}]},"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":[{"creatorAffiliations":[{"affiliationNames":[{"affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Suzuki, Nobuhiro","creatorNameLang":"en"},{"creatorName":"鈴木, 伸洋","creatorNameLang":"ja"},{"creatorName":"スズキ, ノブヒロ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Suzuki","familyNameLang":"en"},{"familyName":"鈴木","familyNameLang":"ja"},{"familyName":"スズキ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Nobuhiro","givenNameLang":"en"},{"givenName":"伸洋","givenNameLang":"ja"},{"givenName":"ノブヒロ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3310","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hagiwara, Kiyoshi","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"萩原, 清司","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"ハギワラ, キヨシ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Hagiwara","familyNameLang":"en"},{"familyName":"萩原","familyNameLang":"ja"},{"familyName":"ハギワラ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Kiyoshi","givenNameLang":"en"},{"givenName":"清司","givenNameLang":"ja"},{"givenName":"キヨシ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3325","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"epidermal differentiation; larval skin; epidermal evolution","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":"トビハゼ浮遊期仔魚の皮膚の微細構造","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"トビハゼ浮遊期仔魚の皮膚の微細構造","subitem_title_language":"ja"},{"subitem_title":"Epidermal Ultrastracture of Pelagic Larvae of the Mudskipper, Periophthalmus modestus (Gobiidae)","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951205920"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-25"},"publish_date":"2024-04-25","publish_status":"0","recid":"2003204","relation_version_is_last":true,"title":["トビハゼ浮遊期仔魚の皮膚の微細構造"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-04-11T05:13:07.899860+00:00"}
