Fig. 4From: Icariin protects rats against 5/6 nephrectomy-induced chronic kidney failure by increasing the number of renal stem cellsIcariin increased the protein levels of HGF and BMP-7 while reduced TGF-β1 level. The protein levels of TGF-β1 (a), HGF (b), and BMP-7 (c) in rat kidney were assayed by immunohistochemical staining with specific antibodies. Representative pictures and the quantitative summaries were given. *, p < 0.01 compared to sham group; #, p < 0.01 compared to CKD model groupBack to article page
