Protein adsorption to scaffolds upon incubation in serum-containing medium ((+)FBS): effect of plasma functionalization and aging conditions. Relative amounts of adsorbed (A) fibronectin, (B) vitronectin, and (C) albumin to untreated scaffolds and fresh and aged MA-VTMOS, APTMS, and argon plasma-treated scaffolds. Data presented as average ± s.d. and statistical significance performed using two-way ANOVA with Tukey’s multiple comparison test (n.s., p > 0.05, *$p < 0.05, **$$p < 0.01, ***$$$p < 0.0001; * for comparisons among treatments within aged or fresh scaffolds; $ for comparisons among fresh and aged for each plasma treatment).
