Hydrogels are highly versatile materials with immense potential for tissue engineering and regenerative medicine owing to their biocompatibility, tunable mechanical properties, ability mimic the natural extracellular matrix. Their 3D porous structure allows encapsulation delivery of bioactive molecules, making them ideal candidates drug systems. In repair, particularly bone regeneration, hydrogels can serve as carriers that release therapeutic agents in a controlled manner, thus enhancing healing process. Zeolitic Imidazolate Framework-8 (ZIF-8) nanoparticles recombinant human Bone Morphogenetic Protein (rhBMP-2) molecules were incorporated solely (ZIF@GelMA) or association (BMP@ZIF@GelMA) into gelatin modified by methacryloyl hydrogel (GelMA) investigate its physical osteogenic properties. characterized Scanning Electron Microscopy rheological tests. We analyzed degradation BSA profile BMP@ZIF@GelMA samples throughout 0, 1, 3, 7, 14, 28 days. Cell adhesion formation markers hydrogel-encapsulated dental pulp cells using immunocytochemistry molecular analysis. ZIF@GelMA exhibited viscoelastic increased storage modulus when rhBMP2 was present. BSA@ZIF@GelMA showed balanced rate BSA. The upregulated expression cell genes, BMP-2 introduced, levels remarkably elevated. presents several favorable factors promote cellular encouraging further prospects advanced applications repair.
