Area of positive TGF-β1, Smad2, Smad3, Smad4, and Smad7 expression in the rats ovaries. The figures illustrate the immunohistochemistry profiles of (A) TGF-β1, (B) Smad2, (C) Smad3, (D) Smad4, (E) and Smad7 proteins in the ovary. (scale bar = 100 μm; the amplified area is defined by the black rectangle, high magnification scale bar = 50 μm). The positive of (F) TGF-β1, (G) Smad2, (H) Smad3, (I) Smad4, (J) and Smad7 in the ovary (n = 3). Versus the Normal group, ∗p < 0.05 and ∗∗p < 0.01; versus the PCOS group, #p < 0.05 and ##p < 0.01. Statistics are the mean ± SD.
