Immunostaining of specific mammary epithelial cell protein markers. Staining for CK18, ESA, MUC-2, and CK14 were observed in BMECs and BME65Cs cells, whereas staining for the isotype controls was faint (small pictures in bottom- right corner). PI was added as an immunofluorescence counterstain. Bars: 20 μm.
