| Outline of Final Research Achievements |
We aimed to determine the role of cancer-associated mesothelial cells (CAMCs) in the promotion of tumor neovascularization and vascular permeability via enhanced VEGF production and loclal immunologic effects. We examined whether a characteristic morphological change in human peritoneal mesothelial cells (HPMCs) was observed in the presence of malignant ascites and tumor-derived TGF-β. We focused on the enhanced production of VEGF in CAMCs and its crucial role in endothelial tube formation. Ｗe found that EOC-derived TGF-β induced typical EMT-like morphological alteration in HPMCs, which was associated with CAMCs. We further discovered that CAMCs play a crucial role in the enhanced VEGF production.Furethermore we showed that IL-33 secretion was elevated in high metastatic cell lines.The novel mechanism of CAMCs as a facilitator of EOC progression and immnunological effect are displayed by microenvironmental cell-to-cell communication.
