Average compressive moduli of elasticity of acellular microsphere-based scaffolds at week 0. All values are expressed as the average + standard deviation (n = 6). The TCP/HAp groups had significantly lower moduli than the BLANK and BMP controls. *significant difference from the BLANK negative control group, @significant difference from the BMP positive control group, and $significant difference from the TCP/HAp 7:3 group (p < 0.05).
