Figure 1 Representative images from site A paraffin tissue illustrating the divergent appearance of (A) “normal” versus (B) “low” versus (C) “absent” nucleolar channel system appearance as detected by indirect immunofluorescence with mAb414. Note the equal labeling of the nuclear pore complexes outlining the epithelial cell nuclei of all panels and the NCSs within nuclei in (A and B), some of which are indicated (arrows). Bar = 7 μm.
