Supplemental Figure 1 for Macrophage Secreted TGF-β1 Contributes to Fibroblast Activation and Ureteral Stricture Following Ablation Injury

<p>Supplemental Figure 1. TGF-&beta;1 (brown) and Masson Trichrome (blue) staining of healthy ureteral wall adjacent to the site of IRE treatment. A-D) Sparse numbers of spindle shaped cells (fibroblasts, arrows) can be seen in healthy ureter adjacent to IRE treated ureter but their numbers were not different from what was observed in untreated control ureter. F-H) Ureteral wall adjacent to the site of IRE treatment stains positive for collagen (blue) but the levels remain invariant through different timepoints. The muscularis (asterisk) of the ureteral wall is preserved, with no evidence of scarring.</p>
