CCR2 expression in glomerular mesangial cells in IgAN children. Expression of CCR2 in kidney tissue of controls (A: upper row) and IgAN children (A: lower row) was detected by DAB staining. In the last column of A and B showed single glomerular cross sections. The Bar of first column from left in A was 200 µm, and then second column was 100 µm, and the third, last column and B was 50 µm. Relative optical density (OD) of kidney CCR2 expression in controls and IgAN patients (C) was calculated by Image J software. Compared with control group, **P < 0.01
