The expression of MCP-1 in rat normal cornea and in alkali-burned cornea in the vehicle and PPARα agonist groups at day 1. The expression of MCP-1 could not be detected in the epithelial basement cells in normal cornea of center (A) and of limbus (D). In the alkali-burned cornea of center (B,C) and limbus (E,F) in the Vehicle (B,E) and PPARα agonist (C,F) groups, diffuse expression of MCP-1 in the epithelial basement cells was observed during re-epithelialization. However, the expression of MCP-1 was weaker in the PPARα agonist group (C,F) compared to these regions of the Vehicle group (B,E), suggesting that PPARα agonist inhibited the expression of MCP-1 in the epithelial basement cells. Scale bar: 20 μm.
