Effective tissue regeneration and immune responses are essential for the success of biomaterial implantation. Although interaction between synthetic materials biological systems is well-recognized, role surface topographical cues in regulating local osteoimmune microenvironment─specifically, their impact on host cells, dynamic interactions─remains underexplored. This study addresses this gap by investigating topography osteogenesis immunomodulation. We fabricated MXene/hydroxyapatite (HAP)-coated surfaces with controlled 2.5D nano-, submicro-, microscale patterns using our custom bottom-up patterning method. These engineered were employed to assess behavior osteoblast precursor cells macrophage polarization. Our results demonstrate that MXene/HAP-coated crumpled significantly influence osteogenic activity polarization: these notably enhanced cell spreading, proliferation, differentiation facilitated a shift macrophages toward an anti-inflammatory, prohealing M2 phenotype. The observed indicate physical from topographies, combined chemical MXene/HAP coatings, synergistically create favorable microenvironment. presents first evidence employing MXene/HAP-multilayer coated finely concurrently facilitate immunomodulation improved implant-to-tissue integration. tunable topographic coatings coupled facile scalable fabrication process make them widely applicable various biomedical purposes. highlight potential multilayer improve vivo performance fate implants modulating response at material interface.

Osteoarthritis (OA), a disabling joint inflammatory disease, is characterized by the progressive destruction of cartilage, subchondral bone remodeling, and chronic synovitis. Due to prolongation human lifespan, OA has become serious public health problem that deserves wide attention. The development related numerous factors. Among factors, nitric oxide (NO) plays key role in mediating this process. NO small gaseous molecule widely distributed body, its synthesis dependent on synthase (NOS). an important various physiological processes such as regulation blood volume nerve conduction. Notably, acts double-edged sword diseases. Recent studies have shown redox derivatives might be closely both normal pathophysiological conditions. They can play vital roles cell-conditioning agents for osteoclasts, osteoblasts, chondrocytes. Moreover, they also induce cartilage catabolism cell apoptosis. Based different conditions, NO/NOS system act anti-inflammatory or pro-inflammatory agent OA. This review summarizes effects all joints well possible new treatment strategies targeting system.
