Effect of pH on COM crystal adhesion on renal tubular cells. Crystal-cell adhesion assay was performed using plain COM crystals under varying pH (from 5.0 to 8.0). (A) Microscopic examination of the crystals remained and adhered on the MDCK cell monolayer after washing in each condition (original magnification power was 400×). (B) Quantitative data of the adherent COM crystals from at least 15 randomized high-power fields (HPF) per culture well in each replicate. The data are reported as mean ± SEM of the data obtained from 3 independent experiments. *p < 0.05 vs. pH 5; ***p < 0.001 vs. pH 5; ## p < 0.01 vs. pH 6; $ p < 0.05 vs. pH 7.
