Fig. 5From: Note on the use of different approaches to determine the pore sizes of tissue engineering scaffolds: what do we measure?Structural porosity of differently cross-linked scaffolds expressed by means of differing 2D and 3D parameters. Statistically significant differences are evident between each of the 6 different porosity parameters of each scaffold before and after the differing cross-linking procedures except for those pairs denoted by open circle (Kruskal–Wallis, Bonferroni procedure, 0.05)Back to article page
