Relative mRNA expression of selected inflammatory and early bone-forming markers from different groups implanted in aged rat calvaria bone defects after 2 weeks. Unfunctionalized scaffold (Control), functionalized scaffold (PA), and autograft. Data are presented as fold change normalized to GAPDH (*p < 0.05, **p < 0.01, ***p < 0.001)
