Implication
Supports statin EPC effects in mouse vascular injury; leaves open translation to human restenosis prevention.
Key Points
- To clarify the role of bone marrow–derived endothelial progenitor cells in vascular lesion development and evaluate whether rosuvastatin enhances vascular repair.
- Transplanted mice with bone marrow transfected with green fluorescent protein and subjected them to carotid artery injury to induce neointimal formation.
- Administered rosuvastatin at 20 mg/kg body weight per day and analyzed vascular tissues using fluorescence microscopy and immunohistology.
- Bone marrow–derived progenitor cells mobilized directly to vascular lesions and contributed to the reendothelialization of injured vessel walls.
- Rosuvastatin expanded the circulating endothelial progenitor cell pool, accelerated reendothelialization, and significantly reduced neointimal lesion formation.

Outcome
Reendothelialization and neointimal formationsurrogate
Statin therapy promotes bone marrow-dependent reendothelialization and reduces neointimal formation after vascular injury in a mouse model.
