Supplemental Figure S10.

Representative images of Ki-67, uroplakin 3a (UPK3), and KRT5 coimmunostaining 3 days after sham injury. Triple-label immunofluorescence for Ki-67 (red), UPK3 (white), and KRT5 (green) 3 days after sham injury shows few Ki-67⁺ cells in either PBS-pretreated (A–C) or keratinocyte growth factor (KGF)–pretreated (D–F) mice; the single Ki-67⁺ cells in the sections from each group are UPK3⁺ and KRT5⁻ (arrowheads). A and D: Blue indicates DAPI. Dotted lines indicate demarcation between urothelial layer and underlying lamina propria. Scale bar = 50 μm (A–F). L, lumen.
