Figure 2From: Fabrication and in vitro evaluation of an articular cartilage extracellular matrix-hydroxyapatite bilayered scaffold with low permeability for interface tissue engineering Structural characterisation of the bilayered scaffolds. A: Gross appearance of the scaffold prototype. B–F: Analysis of longitudinal sections of the bilayered scaffold by SEM showing the upper layer (B), interface region (C and D), and nanofibrous ECM orientation in the upper layer of the scaffold wall at a high magnification (E) and in the lower layer (F).Back to article page
