Density measurements of the decellularized scaffolds were made using a 10 mL pycnometer (Bomex, Bejing, China). Room temperature DI H 2 O was used as the medium for gravimetric displacement. The volume of the pycnometer was calculated by dividing the total mass of water that it could contain by the density of water.
WebCells were seeded onto poly(l-lactide-co-ε-caprolactone) [poly(LLA-co-CL)] scaffolds at two different densities: low density (1 × 10(6) cells/scaffold) or high density (2 × 10(6) cells/scaffold) using spinner modified flasks and examined after 1 and 3 weeks.
