Objectives: Angiogenesis is a process that is indispensable in cancer progression. A complex network of tumor and microenvironment stimuli regulate angiogenesis. VEGF, TGF-β1, IL-8 and TNF belong to the angiogenic factors that are key points in vessel formation. The aim of the study was to assess h-VEGF, TGF-β1, IL-8 and TNF secretion by human ovarian cell lines. Material and methods: OVA 2, OVA 4, OVA 9, OVA 11 and OVA 14 cell lines were established in our laboratory. The cells derived from primary and metastatic tumors of epithelial and non-epithelial origin. SK-OV-3, MDAH 2774, CAOV-1 and OVP-10 were the cell lines obtained from other sources. The concentration of VEGF, TGF-β1 and IL-8 was determined in culture supernatants by using the ELISA tests. Results: OVA 11 secreted all the evaluated cytokines. MDAH 2774 was the source of h-VEGF, TGF-β1, IL-8. SK-OV-3 secreted h-VEGF and IL-8. OVA 4 secreted TGF-β1 and TNF. TNF was the only studied cytokine secreted by CAOV-1, OVA 2 and OVA 9 cell lines. OVA 14 did not secret any of the cytokines. Conclusions: The investigated cell lines present heterogeneous profile of angiogenic cytokine secretion and seem to be an interesting set of models for the study of angiogenic signaling, or target therapy.

Cel: Angiogeneza jest procesem niezbędnym do progresji raka. Złożona sieć bodźców pochodzących od guza i z mikrośrodowiska reguluje angiogenezę. VEGF, TGF-β1, IL-8 i TNF należą do czynników angiogennych, które odgrywają kluczową rolę w tworzeniu naczyń. Celem pracy była ocena wydzielania h-VEGF, TGF-β1, IL-8 i TNF przez ludzkie linie raka jajnika. Materiał i metoda: Linie OVA 2, OVA 4, OVA 9, OVA 11 oraz OVA 14 zostały ustalone samodzielnie. Komórki pochodziły z pierwotnych lub przerzutowych guzów jajnika pochodzenia nabłonkowego lub nienabłonkowego. Linie SK-OV-3, MDAH 2774, CAOV-1 oraz OVP-10 pochodziły z innych źródeł. Stężenie VEGF, TGF-β1 i IL-8 określano w supernatantach hodowli komórkowych w teście ELISA. Wyniki: Linia OVA 11 wydzielała wszystkie badane cytokiny. Linia MDAH 2774 była źródłem h-VEGF, TGF-β1, IL-8. Linia SK-OV-3 wydzielała h-VEGF oraz IL-8. Linia OVA 4 wydzielała TGF-β1 i TNF. TNF był jedyną cytokiną wydzielaną przez linie CAOV-1, OVA 2 oraz OVA 9. Linia OVA 14 nie wydzielała żadnej spośród badanych cytokin. Wnioski: Badane linie komórkowe stanowią heterogenną grupę nowotworów wydzielających cytokiny o właściwościach angiogennych i wydają się interesującym panelem do badań nad procesami angiogenezy czy terapii celowanej.
