Figure 2. Scaffold characterization.

Mercury porosimetry showed an increase in total surface area with increasing scaffold density (a), and a decrease in pore sizes with increasing scaffold density (b). μCT data indicated that bone scaffold porosity was decreasing with increasing scaffold density (c). Compressive elastic modulus was increasing with increasing scaffold density (d). Data represent average ± SD of n = 4 measurements, (*p<0.05; **p<0.01; ***p<0.001).
