SEM imaging and pore size analysis of mineralized collagen and mineralized collagen–amnion scaffolds. (A) SEM image of the amniotic membrane. (B) SEM image of a mineralized collagen scaffold. (C) SEM image of a mineralized collagen–amnion scaffold. (D) Representative images of mineralized collagen and mineralized collagen–amnion scaffolds sectioned transversely and longitudinally and stained with aniline blue to determine pore size. (E) Average pore size of mineralized collagen and mineralized collagen–amnion scaffolds. * indicates that the mineralized collagen scaffold has a significantly (P < 0.05) higher average pore size than the mineralized collagen–amnion scaffold. Data are expressed as mean ± standard deviation (n = 3)
