Fig. 4From: Therapeutic effect of urine-derived stem cells for protamine/lipopolysaccharide-induced interstitial cystitis in a rat modelWestern blot and immunofluorescent (IF) staining for the antioxidative markers HO-1- and NQO-1-positive cells in urinary bladders at 4 days after IC induction (n = 5). a,b The protein expression of heme oxygenase-1 (HO-1) and NAD(P)H quinine oxidoreductase (NQO-1) by Western blot was remarkably lower in the control group (N) than in the interstitial cystitis (IC) and IC + urine-derived stem cell (USC) groups, and notably lower in the IC group compared to the IC + USC group. c A statistical chart of the relative optical density of HO-1/GAPDH in each group (n = 5). d A statistical chart of the relative optical density of NQO-1/GAPDH in each group (n = 5). e–g Microscopic (400×) IF staining for the number of HO-1-positive cells infiltrated into the bladder in all groups. h–j Microscopic (400×) IF staining for the cellular expression of NQO-1 in the urinary bladder in the three groups of animals. k A statistical chart reveals the index of HO-1-positive cells in bladder tissue (n = 5). l A statistical chart reveals the index of NQO-1-positive cells in the three groups of bladder tissue (n = 5). *P < 0.05, versus the control group; # P < 0.05, versus the IC groupBack to article page
