<p><b>(A)</b> Representative images of TUNEL staining (brown) of kidney sections from the Sham and UUO groups on days 7, 10, and 14. (magnification, ×200; bars = 250 μm) <b>(B)</b> Graph indicating the number of apoptotic cells in mice after UUO. <b>(C)</b> Representative Ki67 immunofluorescence staining of kidneys with UUO at days 7 (magnification, ×200; bars = 250 μm). Red arrows indicate Ki67+ epithelial cells, and white arrows indicate Ki67+ tubulointerstitial cells. <b>(D)</b> Graph showing the number of proliferative cells in renal tubule and interstitial compartments. The data are expressed as the mean ± SD. * P<0.05, ** P<0.01, *** P<0.001 vs. WT mice of the Sham group; #P<0.05, ## P<0.01 vs. WT mice of the respective groups.</p
