A highly crosslinked composite dextran-based scaffold (named DexFoam) was tailored to overcome specific deficiencies of polymeric and ceramic bone scaffolds and to guarantee a bone-mimicking microenvironment for the proliferation of human mesenchymal stem cells in vitro. The creep resistance for up to 90% compressive stain, the capability to regain the original shape after deformation, and the good thermal stability in both physiological and “body limit” conditions make DexFoam a valid alternative to the currently available bone scaffolds. Histopathological evaluation for host reaction and tissue colonization of DexFoam scaffold, implanted subcutaneously in mice, demonstrated its in vivo biocompatibility and biodegradability.
