CNOT8 and neoplasm: To evaluate whether CAFs contribute to tumor growth in the peritoneal cavity, we inoculated cancer cells (MKN45-Luc) or co-inoculated cancer cells and CAF (MKN45-Luc + CAF2) into the peritoneal cavity of BALB/c nu/nu mice and compared the tumor growth of MKN45-Luc between groups.
