Mechanical properties. Experimental values of compressive modulus of elasticity of constructs, Ec, (Left Y-Axis) and estimated values of compressive modulus of elasticity of formed tissue, Et, (Right Y-Axis) are shown at two different locations (‘Edge’ and ‘Center’) ‘Control’ constructs had no microchannels, ‘100C_100S’ represents constructs containing 100 micrometer channels with 100 micrometers spacing between them. ‘100C_50S’ represents constructs containing 100 micrometer channels with 50 micrometers spacing between them. At least eight samples were used per condition and the error bars indicate the standard error of the mean.* denotes statistically significant difference (p<0.05).
