Intravenous transfusion of endothelial progenitor cells helps to repair sites of vascular injury.

This study evaluated the role of intravenously transfused endothelial progenitor cells (EPCs) on reendothelialization and neointima formation in a mouse model of arterial injury. They found that cell transfusion caused enhanced reendothelialization associated with a reduction of neointima formation. They conclude that their results provide additional information for the treatment of vascular dysfunction and prevention of restenosis after angioplasty.
