Growth curves of rat aortic smooth muscle cells cultured in a serum-free medium on (A–C) HDPE; or (D–F) LDPE in non-treated form (N), treated with plasma for 50, 100 or 300 s (50, 100, 300), and subsequently grafted with fibronectin (Fn) and bovine serum albumin (BSA). A standard cell culture polystyrene dish (PS) was used as a reference material. Mean ± S.E.M. from 20 measurements (day 2 and 4) or 4 measurements (day 6). ANOVA, Student–Newman–Keuls Method. Statistical significance: * p ≤ 0.05 compared to the non-modified LDPE or HDPE.
