Polyethylene (PE) was modified by an Ar plasma and after that was grafted with poly(ethylene glycol) (PEG, molecular weight 300 and 20 000) and seeded with rat vascular smooth muscle cells. The plasma treatment and the subsequent PEG grafting leads to dramatic changes in the PE surface morphology, roughness andwettability. The PEG grafting of the plasma-treated PE does not increase VSMC adhesion but it results in dramatic increase of VSMC proliferation
