| Outline of Final Research Achievements |
We investigated the function of peritoneal mesothelial cells (PMCs) in peritoneal dissemination of ovarian cancer. When PMCs were cultured with either carcinomatous ascites, conditioned medium of ovarian cancer cell line or TGF-β, PMCs were dramatically changed from cobblestone-like to fibroblast-like morphology. In the changed PMCs, the expression of epithelial-mesenchymal transition marker and cancer-associated fibroblast marker were increased. In the changed PMCs, the secretion of some cytokine were also elevated. Ovarian cancer cells showed a greater capacity for migration toward changed PMCs than toward normal PMCs. The changed PMCs may have positive effect on ovarian cancer cells.
