Histologic and biomechanical examination indicated bone formation in all cases, with biomechanical properties of the regenerated bone close to those of bone tissue. The results of this study suggest that BioGran exhibits osteoconductive properties and efficacy as an alloplastic bone-grafting material.
This is due to their exceptional properties that include (1) similarity, in terms of structure and chemical composition, to the mineral phase of bone, and (2) osteoconductivity, that is, the The property of osteoconductivity describes the way the graft acts as a scaffold on which host cells can attach and proliferate, leading to osseointegration. Osteoinductivity, on the other hand, describes the cellular signaling potential of a graft. Osteoconductive properties of PLGA/Cu(I)@ZIF-8 scaffolds Alkaline phosphatase (ALP) is an early marker of osteogenic differentiation in the cell mineralization progress [ 31 ]. The osteogenic differentiation of MSCs cultured on the surface of PLGA scaffolds or PLGA/Cu(I)@ZIF-8 scaffolds was investigated by ALP staining and ALP activity assay.
