Figure 1From: Fabrication and in vitro evaluation of an articular cartilage extracellular matrix-hydroxyapatite bilayered scaffold with low permeability for interface tissue engineering Permeability determination. A: Experimental set-up for the measurement of permeability. B: Permeability changes in different types of scaffolds (7 w/v% HAp) under compressive strain. C: Experimentally measured permeability of bilayered scaffolds with various HAp contents and applied compressive strain. The data are means ± SDs, * p < 0.05, versus respective bilayered scaffolds at the same strain.Back to article page
