The cells were continuously grown in either random (a, b, and d) or A19 (c and e) oligonucleotides on Transwell™ filters, fixed, and processed for indirect immunoperoxidase with anti-CK19 mAb (K4.62). (a and c) Apical cytoplasm; (d and e) basal cytoplasm; (b) lateral domain. The black arrowheads point at peroxidase positive intermediate filaments. (D) White arrowheads show desmosomes; Nu, nucleus; *, microvillus. Bar: (a and c–e) 0.52 μm; (b) 0.35 μm.
