However, graft failure occurs frequently due to insufficient infiltration of blood vessels (neoangiogenesis), while the maintenance of hepatocyte phenotype and function requires in vivo development of the complex cellular organization of the hepatic lobule. Here we describe a subcutaneous human liver construction allowing for rapidly vascularized grafts by transplanting engineered cellular sheets consisting of human primary hepatocytes adhered onto a fibroblast layer. The engineered hepatocyte/fibroblast sheets (EHFSs) showed superior expression levels of vascularization-associated growth factors (vascular endothelial growth factor, transforming growth factor beta 1, and hepatocyte growth factor) in vitro. EHFSs developed into vascularized subcutaneous human liver tissues contained glycogen stores, synthesized coagulation factor IX, and showed significantly higher synthesis rates of liver-specific proteins (albumin and alpha 1 anti-trypsin) in vivo than tissues from hepatocyte-only sheets. The present study describes a new approach for vascularized human liver organogenesis under mouse skin. This approach could prove valuable for establishing novel cell therapies for liver diseases.","subitem_description_type":"Abstract"}]},"item_5_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"長崎大学学位論文 学位記番号:博(医歯薬)乙第45号 学位授与年月日:平成28年8月3日","subitem_description_type":"Other"},{"subitem_description":"Author: Yusuke Sakai, Kosho Yamanouchi, Kazuo Ohashi, Makiko Koike, Rie Utoh, Hideko Hasegawa, Izumi Muraoka, Takashi Suematsu, Akihiko Soyama, Masaaki Hidaka, Mitsuhisa Takatsuki, Tamotsu Kuroki, Susumu Eguchi","subitem_description_type":"Other"},{"subitem_description":"Citation: Biomaterials, 65, pp.66-75; 2015","subitem_description_type":"Other"}]},"item_5_description_69":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Nagasaki University (長崎大学), 博士(医学) (2016-08-03)","subitem_description_type":"Other"}]},"item_5_dissertation_number_65":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"乙医歯薬第45号"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"115426","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sakai, Yusuke"}]}]},"item_5_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier Ltd."}]},"item_5_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.biomaterials.2015.06.046","subitem_relation_type_select":"DOI"}}]},"item_5_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(C) 2015 Elsevier Ltd.
