Expression of alpha smooth muscle actin in living donor liver transplant recipients

Figure 2 Change in alpha smooth muscle actin expression in the two pediatric cases with immune tolerance. A: The α-SMA-positive area continued to increase over time in both cases. Case 1 showed F0 fibrosis in the liver at all time points, whereas Case 2 showed a slight progression of fibrosis (F1) eight years after the cessation of immunosuppressive treatment; B: The findings of Azan-Mallory staining and the α-SMA-positive area determined by immunohistochemical analysis are shown. α-SMA: Alpha smooth muscle actin; IS: Immunosuppression.
