FIG. 7.

Fluorescent immunostaining to proliferating cell nuclear antigen shows proliferating cells in the regenerating bladder at 2 weeks (b), 4 weeks (c), and 8 weeks (d) post-STC in greater abundance compared with control tissue (a). It is noticeable that the number of proliferating cells is decreasing over time, which is more evident at the 8 weeks time point when compared with the 2 weeks. Proliferating cell nuclear antigen staining is shown with Texas Red, and nuclei are stained with 4′,6-diamidino-2-phenylindole (blue). All images are shown at 40 × magnification.
