The present study focuses on the synthesis and characterization of hydroxyapatite-collagen nanoparticles incorporated polyanhydride paste and investigating its bone regeneration capacity in vitro. Si, Sr, and both Si/Sr doped hydroxyapatite-collagen nanoparticles to the extent 10 wt% were added to polyanhydride monomer mixture containing 40 wt% MSA, 40 wt% MCPH and 10 wt% PEGDA and subsequently photopolymerized as previously mentioned. Incorporation of hydroxyapatite-collagen nanoparticles to the extent of 10 wt% into polyanhydride matrix enhanced compressive strength of the hardened paste from 30 to 49 MPa. MTT assay showed that mesenchymal stem cell proliferation was significantly higher in Si/Sr binary doped hydroxyapatite-collagen-polyanhydride sample as compared to other samples. Again from immunocytochem. study using confocal images suggested that expression of osteocalcin, a marker indicating differentiation into osteoblast, was the highest in Si/Sr binary doped hydroxyapatite-collagen-polyanhydride sample against the other samples studied in this case. This study thus summarizes the development of photocurable biocomposites containing polyanhydride and Si, Sr doped hydroxyapatite-collagen nanoparticles that exhibited tremendous promise to regenerate bone tissues in complex-shaped musculoskeletal defect sites.
