Growth curves of rat aortic smooth muscle cells cultured in a serum-supplemented medium on HDPE (A–C) or LDPE (D–F) in non-treated form (N), treated with plasma for 50, 100 or 300 s (50, 100, 300), and subsequently grafted with fibronectin (Fn) or bovine serum albumin (BSA). A standard cell culture polystyrene dish (PS) was used as a reference material. Mean ± S.E.M. from 20 measurements on microphotographs (day 2 and 4) or 200 measurements on a ViCell XR Analyser (Beckman Coulter, Brea, CA, USA) (day 6). ANOVA, Student–Newman–Keuls Method. Statistical significance: * p ≤ 0.05 compared to non-modified HDPE or LDPE.
