Osteogenic gene expression of mineralized collagen–amnion scaffolds in normal growth media and inflammatory media. Gene expression was evaluated by RT-PCR and normalized to the expression of cells before seeding on scaffolds. * indicates that the mineralized collagen scaffold was significantly (P < 0.05) greater than the mineralized collagen–amnion scaffold on the same day. Data are expressed as mean ± standard deviation (n = 5)
