Figure 3. Effects of BDL or TAA on the expression of α-SMA in the liver.
Brown color indicates positive. (A) negligible positive immunostaining in female normal rat livers; (B) strong α-SMA expression in liver of BDL rats; (C) negligible positive immunostaining in male normal rat livers; (D) α-SMA expression markedly increased in TAA rat livers. (α-SMA immunohistochemistry, haematoxylin counterstain, ×100).
