IF staining of several ovarian epithelial cell markers on the 7th day after induction of iPS cells. Expression levels of cytokeratin 7, ERβ, and Ki-67 proteins were elevated in the miR-17-3p-transfected iPS group compared with the miR-mut-transfected iPS group. However, fibronectin and vimentin protein levels were decreased in the miR-17-3p-transfected iPS group compared with the miR-mut-transfected iPS group after differentiation. Scale bar=50 μm. Original magnification, 200×. IF, immunofluorescence staining.
