Fig. 6From: Human umbilical cord-derived mesenchymal stem cells improve the function of liver in rats with acute-on-chronic liver failure via downregulating Notch and Stat1/Stat3 signalingThe effects of hUC-MSC transplantation on liver fibrosis in rats with ACLI. ACLI rats were transplanted with hUC-MSCs or 0.9% sodium chloride as a control, and liver sections from ACLI rats 6 weeks post-hUC-MSC transplantation were used for immunohistochemical staining of α-SMA, desmin, MMP9, and TIMP1 and microscopic examination (n = 3/group). Representative photographs are shown (a). Positive staining was quantified and is presented as the mean ± SD (b). *P < 0.05, **P < 0.01Back to article page
