Microscopic findings for identifying the podocyte components of p-cadherin and synatopodin in glomeruli by day 60 after CRS induction. A-F: Illustrating microscopic finding (400 ×) of immunohistochemical positively-stained p-cadherin (gray color) in glomeruli. G: Analytical results of number of p-cadherin+ cells, * vs. other groups with different symbols (†, ‡, §, ¶, #), P<0.0001. H-M: Illustrating immunofluorescent microscopic finding (400 ×) of positively-stained synatopodin (green color) in glomeruli. N: Analytical results of number of synatopodin, * vs. other groups with different symbols (†, ‡, §, ¶, #), P<0.0001. Scale bars in right lower corner represent 20 µm. All statistical analyses were performed by one-way ANOVA, followed by Bonferroni multiple comparison post hoc test (n = 8 for each group). Symbols (*, †, ‡, §, ¶, #) indicate significance (at 0.05 level). SC = sham control; CKD = chronic kidney disease; CRS = cardiorenal syndrome; Mel = melatonin; Ex4 = exendin-4.
