Figure 2 α -SMA protein expression in liver tissue stained by immunohistochemistry (SP 200 × ) A: Few α -SMA expressions in sham operation group; B: Positive cells of α -SMA resided in portal ducts, fiber septa, perisinuses and around proliferated bile ducts after 2 wk BDL; C: Positively stained areas of α -SMA expression in model groups 1 to 4 wk after common bile duct ligation.
