Mean pore size and aspect ratios of single compartment CG and 80 wt% CGCaP, and 80 wt% multi-compartment CG–CGCaP (CG, interface, CGCaP regions). Results reported as mean±STD with histology sections taken from n = 4 and n = 2 specimens for single-compartment and multi-compartment scaffolds, respectively.
