“…In previous studies, ZIF-8-based nanoparticles have been implicated in governing osteogenic differentiation of BMSCs through piezo channel and yes-associated protein signaling pathways, canonical MAPK signaling, and canonical Wnt/𝛽-catenin signaling. [56][57][58] Our study introduces the novel dimension of NF-𝜅B p65 regulation, further contributing to expanding the existing repertoire of mechanisms through which ZIF-8-based nanoparticles influence osteogenesis.…”

In the context of bone regeneration, nanoparticles harboring osteogenic factors have emerged as pivotal agents for modulating the differentiation fate of stem cells. However, persistent challenges surrounding biocompatibility, loading efficiency, and precise targeting ability warrant innovative solution. In this study, a novel nanoparticle platform founded upon the zeolitic imidazolate framework‐8 (ZIF‐8) is introduced. This new design, CDC20@ZIF‐8@eM‐Apt, involves the envelopment of ZIF‐8 within an erythrocyte membrane (eM) cloak, and is coupled with a targeting aptamer. ZIF‐8, distinguished by its porosity, biocompatibility, and robust cargo transport capabilities, constitutes the core framework. Cell division cycle protein 20 homolog (CDC20) is illuminated as a new target in bone regeneration. The eM plays a dual role in maintaining nanoparticle stability and facilitating fusion with target cell membranes, while the aptamer orchestrates the specific recruitment of bone marrow mesenchymal stem cells (BMSCs) within bone defect sites. Significantly, CDC20@ZIF‐8@eM‐Apt amplifies osteogenic differentiation of BMSCs via the inhibition of NF‐κB p65, and concurrently catalyzes bone regeneration in two bone defect models. Consequently, CDC20@ZIF‐8@eM‐Apt introduces a pioneering strategy for tackling bone defects and associated maladies, opening novel avenues in therapeutic intervention.

This study was designed to develop a fibrin scaffold for optimum in vitro osteogenic differentiation of porcine ASCs. Fibrin scaffolds physically and chemically modified to be stiffer or have higher concentrations of calcium and phosphate ions were hypothesized to enhance osteogenic differentiation compared to control fibrin scaffolds. Treatments during coagulation resulted in six scaffold types for comparison: whole blood controls, red blood cell lysis buffer, calcium chloride, calcium hydrogen phosphate, vacuum, and mechanical compression. Based on the results, fibrin supplemented with granules of calcium hydrogen phosphate (CaHPO4) was determined to be the most suitable formulation of those examined. Using calcium phosphate resulted in a fibrin scaffold that coagulated faster (p = 0.022), had a rougher surface, higher stiffness, and desirable properties for practical use during surgical operations and scaffolds used in bone tissue engineering. Further, osteogenic differentiation was enhanced on scaffolds treated with calcium phosphate. In addition, fibrin scaffolds treated with RBC lysis buffer were also stiffer than untreated controls. These results are partly explained by ASC attachment and fibrin polymerization during coagulation.

Zeolitic imidazole frameworks (ZIFs), which combine the favorable characteristics of tunable porosity, controlled structure, and facile functionalization, are explored as a novel class of nanocarriers for biomedical applications. In this study, different ZIF materials are investigated, including ZIF‐8, ZIF‐67, ZIF‐90, ZIF‐92, and ZIF‐108, with the same sodalite topology as the adenosine‐5′‐triphosphate (ATP)‐triggered drug delivery systems. Results indicated that ZIF‐90 and ZIF‐108 displayed good biological compatibility and efficiently accumulated in the mitochondria through competitive coordination between the metal nodes of the ZIFs and ATP, suggesting efficient intracellular delivery. With further interactions between these metal ions and ATP, the encapsulated drugs are released from the ZIF nanoparticles, thereby achieving optimal anti‐tumor activity. Through a systematic evaluation of the physicochemical properties of different ZIFs, it demonstrates that the surface charges of ZIFs have a significant impact on the cytotoxicity of cells, whereas the Lewis basicity of imidazole‐based ligands plays an essential role in the competitive coordination between the metal ions and ATP. These findings provide a potential method for screening ZIFs based nanocarriers with minimal toxicity and explain the different delivery efficiencies of these materials with similar topologies.
