Growth and characterization of primary epithelial cells. (a) Contrast phase images were taken 3, 6 and 10 days after seeding the cells. (b,c) Cells seeded were fixed and stained with anti-human E-cadherin (b) or with anti-human cytokeratin 14 or 18 (c) antibodies and fluorochrome-conjugated secondary antibodies. DNA was labeled with Hoechst. (d) Epithelial cells and fibroblasts were isolated from one explant and stained (right) or not (left) with FITC-conjugated anti-human E-cadherin antibody, and analyzed by flow cytometry. All experiments were performed using primary epithelial cells isolated from at least 3 donors.
