Notably, SNAI2 expression in the stroma and carcinoma compartment of OC tumor tissues differed widely among patients as follow: 21.3% of the tumors showed high SNAI2 levels in both compartments; 18.2% displayed high SNAI2 in the carcinoma cells and low in the stroma; 23.1% presented high SNAI2 in the stroma and low in the carcinoma and 37.4% had low SNAI2 in both compartments (Fig. 3a). Here, SNAI2 is linked to carcinoma.
