Stem-like cells in malignant glioma express CD133. We examined samples from human pituitary adenoma, a generally benign neoplasm, for CD133 expression using routine immunohistochemical and biochemical methods. Our study of 70 pituitary adenomas (clinically nonfunctioning adenomas and growth hormone-, prolactin-, adrenocorticotropic hormone-, and thyroid stimulating hormone producing adenomas) showed that 18 (25.7%) expressed CD133. This rate was higher in clinically non-functioning (33.3%) than functioning adenomas (12.0%) (p =0.085).\nReal-time PCR assay revealed the expression of CD133 mRNA in samples immunohistochemically positive for CD133. Neither the patient age and gender, nor the tumor size or postoperative recurrence rate correlated with CD133 positivity. CD133+ cells ubiquitously coexpressed CD34, nestin, and VEGFR2 (KDL1). S-100 and GFAP were not coexpressed with CD133. Chromogranin A, Pit-1, SF-1, and NeuroD1 were immune-negative, indicating that CD133+ cells did not have the potential to differentiate into functional endocrine cells. Our data suggest that the expression of CD133 in pituitary adenomas is related to immature endothelial progenitor cells that may play a role in the neovascularization of pituitary adenomas. Further studies are needed to elucidate the significance of CD133+ cells with respect to neovascularization and their sustainable growth in pituitary adenomas.", "subitem_description_type": "Other"}]}, "item_8_full_name_2": {"attribute_name": "著者よみ", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "117979", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "アリタ, カズノリ"}]}]}, "item_8_full_name_3": {"attribute_name": "別言語の著者", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "117980", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "ARITA, Kazunori"}]}]}, "item_8_publisher_23": {"attribute_name": "公開者・出版者", "attribute_value_mlt": [{"subitem_publisher": "鹿児島大学"}]}, "item_8_subject_15": {"attribute_name": "NDC", "attribute_value_mlt": [{"subitem_subject": "494", "subitem_subject_scheme": "NDC"}]}, "item_8_text_24": {"attribute_name": "公開者よみ", "attribute_value_mlt": [{"subitem_text_value": "カゴシマ ダイガク"}]}, "item_8_text_25": {"attribute_name": "公開者別名", "attribute_value_mlt": [{"subitem_text_value": "Kagoshima University"}]}, "item_8_text_30": {"attribute_name": "NIIタイプ", "attribute_value_mlt": [{"subitem_text_value": "Research Paper"}]}, "item_8_text_41": {"attribute_name": "科研費番号 ", "attribute_value_mlt": [{"subitem_text_value": "21591875"}]}, "item_8_version_type_14": {"attribute_name": "著者版フラグ", "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": "有田, 和徳"}], "nameIdentifiers": [{"nameIdentifier": "39093", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "1000090212646", "nameIdentifierScheme": "NRID", "nameIdentifierURI": " "}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2016-10-28"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "21591875seika.pdf", "filesize": [{"value": "958.2 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 958200.0, "url": {"label": "21591875seika.pdf", "url": "https://ir.kagoshima-u.ac.jp/record/8137/files/21591875seika.pdf"}, "version_id": "6a5a524b-efb7-4835-af2a-acbe3c4402b1"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "pituitary adenoma", "subitem_subject_scheme": "Other"}, {"subitem_subject": "CD133", "subitem_subject_scheme": "Other"}, {"subitem_subject": "endothelial progenitor", "subitem_subject_scheme": "Other"}, {"subitem_subject": "angiogenesis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "tumor stem cell", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "research report", "resourceuri": "http://purl.org/coar/resource_type/c_18ws"}]}, "item_title": "下垂体腺腫における腫瘍幹細胞の実態とその機能および分化に関する研究", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "下垂体腺腫における腫瘍幹細胞の実態とその機能および分化に関する研究"}]}, "item_type_id": "8", "owner": "3", "path": ["80"], "permalink_uri": "http://hdl.handle.net/10232/14747", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-12-22"}, "publish_date": "2014-12-22", "publish_status": "0", "recid": "8137", "relation": {}, "relation_version_is_last": true, "title": ["下垂体腺腫における腫瘍幹細胞の実態とその機能および分化に関する研究"], "weko_shared_id": 3}
