Examination of kidney morphology and fibrosis markers in four groups in vivo. A HE, PAS, and Masson staining in each group. B Immunohistochemistry of fibrosis-related markers (Collagen I, Vimentin, and α-SMA) in each group. C Western blot of fibrosis-related markers (Collagen I, Vimentin, and α-SMA) and Kim1 in each group. D–G Relative expression of fibrosis-related markers and Kim1 detected by western blot. *p < 0.05, **p < 0.01, compared with sham group; ^#p < 0.05, ^##p < 0.01, compared with UUO group
