Figure 5: miR-203 inhibits EMT in mouse tumors xenografted with ovarian cancer cells. A, B, C, D. Sections of mouse tumor xenografted from miR-203- expressing and control SKOV3 cells were immunostained with EMT marker genes, Snai2, vimentin and E-cadherin, as well as the cell proliferation maker gene PCNA. Representative images were shown from tumors collected from three different mice xenografted with miR-203 expressing and control SKOV3 cells.
