Abstract:Background. The well established notion that malignant tumours depend on angiogenesis to grow and metastasize focused the investigators interest on tumour vasculature into visualization and validation. Panendothelial markers (CD31, CD34, F8) and CD105 are differentially expressed in angiogenic and normal vessel endothelial cells. Since the former are excellent markers for the normal vasculature, CD105 (endoglin) is more suitable for identifying tumour angiogenesis. Endoglin is a transforming growth factor (TGF)- beta binding receptor, preferentially expressed on endothelial cells of angiogenic tissues, essential for angiogenesis and vascular development. Conclusions. Tumor microvessel density expressed by CD105 immunohistochemical staining in paraffin-embedded tissue section correlates significantly with tumour aggressiveness and prognosis in many solid tumours. Also, targeting of tumour neovasculature specific antigens offers the possibility of future therapeutic approaches.

Title:[Novi označevalec angiogeneze CD105 (endoglin): diagnostični, napovedni in terapevtski pomen]
Abstract:Izhodišča. Angiogeneza je ključna za napredovanje in metastaziranje malignih tumorjev, zato so številne raziskave usmerjene v prikaz in vrednotenje tumorskega žilja ter ugotavljanje povezanosti le-tega z napovedjo poteka bolezni. Panedotelijski označevalci (CD31, CD34 in F8) ter novejši označevalecCD105 so različno izraženi v endotelijskih celicah nastajajočih (predvsem tumorskih) žil in endotelijskih celicah normalnega žilja. Prvi so idealni označevalci normalnega žilja, CD105 (imenovan tudi endoglin) pa je primernejši za prikaz tumorske angiogeneze. Endoglin je receptor za tumorski rastni dejavnik (tumor growth factor-TGF) beta, ki ga najdemo na endotelijskihcelicah angiogenih tkiv. Potreben je pri aktivni angiogenezi v tumorju kot tudi pri razvoju žil pri zarodku. Zaključki. Gostota tumorskega žilja-prikazana z imunohistokemičnim označevanjem CD105 v tkivnih rezinah tumorja in izmerjena s histomorfometričnim metodami-je značilno povezana z agresivnostjo tumorja in napovedjo poteka bolezni pri številnih solidnih tumorjih. Učinkovanje na endoglin, ki je specifični antigen v tumorskem žilju,ima tudi velike terapevtske možnosti.
