The expression of TGF-β1 in the liver grafts and spleens: (a) At the indicated times, the grafts and spleens were harvested and the expression of TGF-β1 was examined using Western blot. (b, c) Quantitative analysis of TGF-β1 in the liver (b) and spleen (c); On POD 7, the MSC-treated mice (Group B) showed significantly higher expression of TGF-β1 than the MSC-untreated mice (Group A; p<0.05). On POD 100, the MSC-treated mice showed significantly lower expression of TGF-β1 than that on POD 7 (p<0.05). On POD 100, the expression of TGF-β1 was not different among the MSC-treated mice and the two groups of control mice (*p<0.05 compared with MSC-treated mice on POD 7).
