Outline of Final Research Achievements

Tumor-derived exosome (TEX) were internalized in both mesothelial and gastric cancer cells in a cellular origin non-specific manner. Expression of adhesion- related molecules, such as fibronectin 1 (FN1) and laminin gamma 1 (LAMC1), were increased in mesothelial cells after internalization of TEX from gastric cancer cell line and malignant pleural effusion. Immunohistochemistry demonstrated higher expression of FN1 and LAMC1 in the disseminated peritoneal membrane than in the benign peritoneal membrane.
