Architecture characterisation. A: Analysis of cross-sectional images of the bilayered scaffold by microCT showing the upper layer (a), interface region (b), and lower layer (c) of the scaffold (position marked by a dashed line). B: Pore size distribution at distinct thicknesses. C: Porosity of the upper and lower layers with various HAp contents. The data are means ± SDs. *p < 0.05.
