M2 macrophages are the major source of MMT in the contralateral kidneys of long term-UUO rats. (A) immunofluorescent multi-staining of kidney sections with antibodies against collagen I (blue), macrophage marker F4/80 (green), and α-SMA (red). (B) fluorescent co-staining of α-SMA (red) with M2 macrophage marker CD206 (green, upper panel) or M1 macrophage marker iNOS (green, lower panel), nuclei were stained with DAPI in blue. Images are representative for n = 12 rats each group. Quantification data are presented as mean ± SEM, n = 6. *p < 0.05 vs. the sham, #p < 0.05 vs. the UUO.
