Figure 4.
Mechanical compression testing of mineralized collagen and mineralized collagen–amnion scaffolds. Elastic modulus is represented by E*, collapsed strain is represented by ε*, and collapsed stress is indicated by σ*. * indicates significantly (P < 0.05) greater average value of the mineralized collagen–amnion scaffold than the mineralized collagen scaffold. Data are expressed as mean ± standard deviation (n = 8)
