Fluorescence images of F344 rat urothelium at day 7 after intravesical instillation with hydrogel entrapped LV-GFP. Fluorescence images revealed the normal urothelium (a) after treatment with (b) H, (c) LV, (d) H-LV, (e) LV-GFP, and (f) H-LV-GFP. The urothelium (U: umbrella cells; I: intermediate cells; B: basal cells; S: subepithelial connective tissue) was counter-stained with DAPI (nuclei, blue; magnification ×40).
