CDH2 and ovarian carcinoma: To further characterize the phenotype of these epithelial ovarian cancer cells, we classified them into three main groups: (1) Krt18+, β-catenin+, and N-cadherin+ (R182 and R2615); (2) Krt18+, β-catenin+, E-cadherin+, Claudin-3+, and Vimentin+ (OVCAR3 and OVCA432); and (3) Krt18-, β-catenin-, E-cadherin-, Claudin-3-, Vimentin+, and Twist+ (SKOV3, F2-R182, 01-28, A2780).
