Figure 7: After treatment with Tangshen formula for 48 h, the expression of ColI and Fn were downregulated in the HK2 cells stimulated with high glucose. Representative immunofluorescence stained with Fn (green) (original magnification (×400), scale bars, 50 μm) (a). Western blot of ColI and Fn (b). Quantitative analysis of ColI (c) and Fn (d) (n = 3 experiments). The data were expressed as the mean ± standard error of the mean of three independent experiments. ^{#}P < 0.05, versus the NC group; *P < 0.05, versus the HG group
