| Research Abstract |
We evaluated the expression of cell adhesion molecules in malignant pleural mesothelioma, and found that CD146 was strongly expressed in mesothelioma cells but not in reactive mesothelial cells, in pleural effusion fluids. Using an orthotopic implantation model of malignant pleural mesothelioma, we showed that CD146 was expressed in diffusely growing thoracic tumors, but not in murine mesothelial cells. Our results suggest that CD146 is up-regulated upon malignant transformation of mesothelial cells, and might be involved in manifestation of cytopathological features of malignant mesothelioma cells. We propose that CD146 is an effective immunostaining marker enabling discrimination between malignant pleural mesothelioma and reactive mesothelium in effusion cytology, and useful for early diagnosis of malignant mesothelioma.
