Figure 4: The expression of transforming growth factor-β1 (TGF-β1) and TGF-β type II receptor in canine prostatic urethra wound after two-micron laser resection of the prostate by immunohistochemical staining. ( a ) An increased TGF-β1 expression in the proliferating prostatic epithelial cells under the wound was shown at 3 days (×200). ( b ) At 2 weeks, an increased TGF-β1 expression in the proliferating prostatic epithelial cells and regenerated epithelial cells were shown (×100). ( c ) At 4 weeks, TGF-β1 expression were strikingly increase in regenerated epithelial cells but returned to weak positive in proliferating prostatic epithelial cells (×100). ( d ) An increased TGF-β type II receptor expression in the proliferating prostatic epithelial cells under the wound was shown at 3 days (×200). ( e ) At 2 weeks, an increased TGF-β type II receptor expression in the proliferating prostatic epithelial cells and regenerated epithelium cells were shown (×100). ( f ) At 4 weeks, TGF-β type II receptor expression were strikingly increase in regenerated epithelial cells but returned to weak positive in proliferating prostatic epithelial cells (×100).
