Peroxisome Proliferator-Activated Receptor α Plays an Important Role in the Expression of Monocyte Chemoattractant Protein-1 and Neointimal Hyperplasia after Vascular Injury

Figure 2

Representative pictures of BrdU-positive cells in carotid arteries from PPARα knockout mouse, WT mouse, and WT mouse treated with Wy14643 at day 4 after injury (100x). (A) PPARα knockout group; (B) WT group; (C) WT group treated with Wy14643. BrdU-positive cells were much more in the PPARα knockout group when compared to WT group. PPARα activation further decreased BrdU-positive cells.
