Figure 4From: Fabrication and in vitro evaluation of an articular cartilage extracellular matrix-hydroxyapatite bilayered scaffold with low permeability for interface tissue engineering Compositional analysis. A: EDX analysis of the bilayered scaffold; solid and dashed arrows highlight the mineralised (upper layer) and unmineralised (lower layer) compartments, respectively. B: FTIR measurements of the cross-linked ACECM scaffold, ACECM-HAp (with 7Â w/v% HAp) bilayered scaffold, and non-cross-linked nanophase HAp crystal particles.Back to article page
