Proliferation activity of rat aortic smooth muscle cells measured by cell numbers achieved on day 2 (A), 5 (B) and 7 (C) after seeding on non-modified PE (Pristine), PE irradiated with plasma (Plasma), PE irradiated with plasma and grafted with glycine (Gly), polyethyleneglycol (PEG) bovine serum albumin (BSA), colloidal carbon particles (C) or bovine serum albumin and C (BSA + C). As a reference material, a tissue culture polystyrene dish (PS dish) was used.
Means ± S.E.M. from three samples for each experimental group, each measured for 50 times. ANOVA, Student-Newman-Keuls method. Statistical significance: *,#, $: p ≤ 0.05 compared to the value on pristine PE, polystyrene dish and PE irradiated with plasma, respectively.
