Delivery Site of Perivascular Endothelial Cell Matrices Determines Control of Stenosis in a Porcine Femoral Stent Model

Perivascular endothelial cell matrices reduced stenosis after stent-induced injury. The effects were not dependent on the formulation but appeared to be dependent on delivery site. Minimally invasive injections of endothelial cell matrices to the adventitia of arteries following peripheral interventions may decrease restenosis rates.
