Synthesis and potential osteogenic applications of Wnt3a-loaded ZIF-8 nanoparticles

The Wnt signaling pathway plays a critical role in bone homeostasis,and the related protein therapy strategies have been reported to have great potential in osseointegration;however,they face formidable challenges such as complex external environments and unavoidable protein denaturation.In this work,we report a novel approach combining the synthesis of metal-organic frameworks(MOFs)and protein encapsulation in a one-pot process based on zeolitic imidazolate framework-8(ZIF-8)and Wnt3a protein,with improved biomechanical behavior and enhanced protein biological response.This combination was designed to enhance the Wnt3a protein function through the improved chemical stability provided by the ZIF-8 crystals.Additionally,the zinc ions contained in the ZIF-8 crystals induced bone homeostasis,further favoring the osteogenesis.The results showed that the Wnt3a protein-loaded ZIF-8 crystals served as efficient drug delivery vehicles to promote osteogenesis,preventing protein denaturation.In particular,Wnt3a-loaded ZIF-8 nanoparticles(Wnt3a@ZIF-8 NPs)had higher efficacy on bone marrow mesenchymal stem cells(BMSCs)than ZIF-8 NPs or Wnt3a proteins,contributing to the osteogenesis through ZIF-8 crystals and intracellular Wnt3a proteins released from Wnt3a@ZIF-8 NPs.Furthermore,polymerase chain reaction(PCR)analysis showed that the osteogenic pathways were upregulated.Overall,the present one-pot process can open up new avenues to develop signaling protein-delivery systems for applications in protein therapy strategies.
