The kidney dysfunction and fibrosis in db/db mice. (A–B) HE stain (n = 3). (C–D) Masson stain (n = 3). (E–F) Sirius red stain (n = 3). (G–H) Reticulocyte fibre stain (n = 3). (I–J) Elastic fibre stain (n = 3). (K–L) The expression and statistics of Collagen-I, Collagen-III and TGF-β proteins in kidney tissue by western blotting (n = 6). The results are presented as the mean ± SEM. The scale bar = 25 or 75 μm. *p < 0.05, **p < 0.01 vs. db/m group. ^#p < 0.05, ^##p < 0.01 vs. db/db group.
