Comparison of specific molecules expressions in grafts.

<p>Renal graft fibrosis was significantly accelerated in acute rejection experimental group. (A) Immunohistochemistry staining (100×) showed that the fibrotic protein expression of α-SMA was significantly upregulated in experimental group. (B) Immunohistochemistry staining (200×) showed that the fibrotic protein expression of TGF-β1 in graft was significantly upregulated in experimental group. (C) Quantitative image analyses showed the protein expression of α-SMA was significantly upregulated in experimental group. (D) Quantitative image analyses showed the protein expression of TGF-β1 was significantly upregulated in experimental group. (E)The fibrotic gene TGF-β1 mRNA expression was significantly upregulated in experimental group. Data were expressed as mean±SEM (n = 4 to 5). *<i>P</i><0.05 versus control group. **<i>P</i><0.01 versus control group.
