CD14 and CD68 inflammatory cell infiltrations in urinary bladder by day 60 after CC induction. A-C. Illustrating the immunofluorescent (IF) microscopic finding (400 ×) of CD14+ cells (green color). D. Analytical results of number of CD14+ cells, * vs. other groups with different symbols (†, ‡), P < 0.0001. E-G. Illustrating the IF microscopic finding (400x) of CD68+ cells (green color). H. Analytical results of number of CD68+ cells, * vs. other groups with different symbols (†, ‡), P < 0.0001. Scale bars in the right lower corner represent 20 µm. All statistical analyses were performed by one-way ANOVA, followed by Bonferroni multiple comparison post hoc test (n = 6 for each group). Symbols (*, †, ‡) indicate significance at the 0.05 level. NC = normal control; CC = chronic cystitis; ECSW = extracorporeal shock wave.
