This unique modification of spiral cleavage is directly associated with the characteristic morphology of bivalves, namely, bilaterally separated shell plates, because the bilateral shell plates are thought to be derived from the bilateral derivatives of 2d1121. In this report, to determine whether the unique cleavage pattern of bivalves is regulated depending on the interaction with other cells or by cell autonomous mechanisms, we performed cell isolation experiments and observed subsequent cleavage patterns of isolated blastomeres. When focusing on the largest derivatives of D blastomeres, 8% of isolated D blastomeres followed the cleavage pattern of normal development up to bilateral cleavage. Importantly, the remainder of the partial embryos ended cleavage before that stage, and none of the isolated blastomeres showed abnormal cleavage patterns. We also examined the development of isolated blastomeres and found that isolated D blastomeres could develop shell plates, whereas larvae developed from AB blastomeres never had shell plates. Based on these observations, we concluded that D blastomeres control their unique cleavage pattern through intrinsic mechanisms and develop shell glands autonomously without any cell–cell interaction with other lineages.","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Wiley-Liss, Inc."}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1002/jez.b.22585","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2014 WILEY PERIODICALS, INC."},{"subitem_rights":"This is the peer reviewed version of the following article: Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 324,1,2015, which has been published in final form at DOI: 10.1002/jez.b.22585.This article may be used for non-commercial purposes in accordance With Wiley Terms and Conditions for self-archiving."}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1552-5007","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hashimoto, Naoki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kurita, Yoshihisa"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Murakami, Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Wada, Hiroshi"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-01"}],"displaytype":"detail","filename":"JEZB_324-1.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JEZB_324-1","url":"https://tsukuba.repo.nii.ac.jp/record/32168/files/JEZB_324-1.pdf"},"version_id":"12255952-ee37-46f6-b16b-ffe0c9926a54"}]},"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":"Cleavage pattern and development of isolated D blastomeres in bivalves","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Cleavage pattern and development of isolated D blastomeres in bivalves"}]},"item_type_id":"5","owner":"1","path":["844","2922"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-01-29"},"publish_date":"2015-01-29","publish_status":"0","recid":"32168","relation_version_is_last":true,"title":["Cleavage pattern and development of isolated D blastomeres in bivalves"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T08:59:15.361603+00:00"}
