Pore size and aspect ratio analysis of chondroitin-6-sulfate isotropic and anisotropic scaffolds cut in the longitudinal and transverse direction. There was no significant difference (p < 0.05) in pore size, however, the pore aspect ratio of the anisotropic scaffolds cut transversely was significantly (p < 0.05) different than the isotropic scaffolds cut longitudinally.

Pore alignment	Orientation	Average pore aspect ratio	Average pore diameter (μm)
Isotropic	Transverse	0.948 ± 0.004	177 ± 19.3
	Longitudinal	0.955 ± 0.003	169 ± 5.2
Anisotropic	Transverse	0.887 ± 0.034	170 ± 25.7
	Longitudinal	0.938 ± 0.007	140 ± 9.5
