Abstract:

Hydroxyapatite nanorods(nHAp) were synthesized using a solution precipitation method to mimic the inorganic composition of natural bone matrix, enhancing the osteoconductivity of the material. Concurrently, cobalt molybdenum phosphate microrods(CPMmr) were synthesized through a hydrothermal method. Their mediated Fenton-like reaction can catalyze the conversion of hydrogen peroxide into hydroxyl radicals, achieving effective tumor cell killing. A porous polyether ether ketone(PEEK) scaffold with continuous interconnected finger-like macropores and micropores was prepared using phase inversion to promote cell migration, nutrient exchange, and tissue ingrowth. CPMmr and nHAp were uniformly dispersed in a composite hydrogel precursor solution of methylacrylated oxidized hyaluronic acid(AHAMA) and polyethylene glycol methacrylate(PEGMA), then they were grafted onto the porous PEEK scaffold surface through UV-initiated polymerization, synthesizing a porous PEEK composite scaffold with osteogenic activity and anti-tumor properties. In vitro cell experiments demonstrated that the porous PEEK composite scaffold exhibits excellent biocompatibility with mouse embryonic osteoblast precursor cells(MC3T3-E1) and significantly enhances the expression levels of osteogenesis-related genes. Furthermore, the presence of CPMmr mediates a Fenton-like reaction within the tumor microenvironment, significantly elevating oxidative stress levels in human osteosarcoma cells(MG-63). This leads to reactive oxygen species accumulation and induces tumor cell apoptosis, demonstrating potent anti-tumor effect.
