Here, we developed an improved direct coculture system together with an optimized RNA extraction strategy to address these limitations. Using this platform, we characterized BHA-induced inflammatory responses at the gene, protein, and transcriptomic levels. Our results showed that the inflammatory activity of BHA is associated with its calcium-enriched surface, which activates the Toll-like receptor 4 signaling pathway. Furthermore, a calcium pre-adsorption strategy was introduced to modulate surface ion activity, which reduced calcium enrichment and attenuated inflammatory signaling.

Here, we engineered a cell-derived, decellularized extracellular matrix (cdECM) into a novel mineralized ECM scaffold by harnessing the polymer-induced liquid precursor (PILP) process, an effective strategy for generating calcium phosphate (CaP) mineralized constructs. Mineral deposition within cdECM was successfully achieved through the PILP mineralization, which stabilizes the amorphous precursor phase and promotes matrix-associated mineralization. The resulting mineralized ECM (mECM) exhibited osteoconductive properties, as evidenced by excellent cytocompatibility and enhanced cell proliferation of osteogenic cells. The mECM also demonstrated osteoinductive potential, as confirmed by enhanced alkaline phosphatase activity, increased calcification, and up-regulated osteogenic gene expression in mouse preosteoblasts and human mesenchymal stem cells. Moreover, mECM promoted M2-like macrophage polarization and enhanced tubular formation of endothelial cells. To enable localized in vivo delivery of both ECM-derived biological cues and minerals, a sheet-type mECM scaffold was fabricated using hyaluronic acid as a supporting matrix and further stabilized by glutaraldehyde vapor crosslinking. In a mouse calvarial defect model, the mECM sheet facilitated new bone formation and supported advanced bone maturation, accompanied by enhanced angiogenesis and an M2-dominant anti-inflammatory milieu at an early time point. Collectively, our findings demonstrate that PILP mineralization can be successfully applied to cdECM for generating a bioactive mECM scaffold with enhanced regenerative capacity, representing a promising biomaterial platform for bone tissue regeneration.</p>","PeriodicalId":93902,"journal":{"name":"Biomaterials research","volume":"30 ","pages":"0410"},"PeriodicalIF":9.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13530373/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148876942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multifunctional bioactive materials capable of both efficient antibacterial action and inflammation modulation represent a promising solution. However, the majority of traditional antibacterial biomaterials possess only a single antibacterial effect, and their synthesis and preparation are intricate, which might restrict their clinical transformation. Chlorogenic acid is a natural compound endowed with anti-inflammatory properties. However, it is beset by certain inherent drawbacks, including poor water solubility and limited bioavailability. To overcome these difficulties, we have fabricated multifunctional nanoparticles (chlorogenic acid-iron nanoparticles, CA-Fe NPs) through the co-assembly of chlorogenic acid and iron ions in a straightforward manner. We found that CA-Fe NPs exhibit excellent photothermal conversion performance in vitro. Upon near-infrared (NIR) irradiation, they exhibit potent broad-spectrum antimicrobial activity against <i>Staphylococcus aureus</i>, <i>Escherichia coli</i>, <i>Candida albicans</i>, <i>Klebsiella pneumoniae</i>, and <i>Pseudomonas aeruginosa</i>. The CA-Fe NPs markedly reduced H₂O₂-induced reactive oxygen species levels and apoptosis in epithelial cells and suppressed lipopolysaccharide-induced M1 macrophage polarization in RAW 264.7 cells. Transmission electron microscopy results revealed enhanced bacterial membrane disruption by CA-Fe NPs under NIR irradiation, causing pronounced protein leakage. Transcriptomic analysis indicates that CA-Fe NPs combined with NIR disrupt the tricarboxylic acid cycle, cell-wall organization, and other metabolic processes. In vivo, within a methicillin-resistant <i>Staphylococcus aureus</i>-infected skin wound model, CA-Fe NPs maintained photothermal efficacy, effectively reduced serum levels of interleukin-1 beta, interleukin-6, and tumor necrosis factor alpha, and accelerated wound healing.

The reciprocal relationship between the inflammatory joint milieu and impaired chondrocyte function drives the progressive deterioration of OA. Inspired by natural metalloenzymes that utilize metal ions as catalytic centers, stable metal-organic frameworks (MOFs) assembled from natural polyphenols and metal ions have emerged as promising candidates for mitigating inflammatory diseases. Nonetheless, numerous nanozymes are limited to restricted antioxidant capacity, failing to eliminate various kinds of reactive oxygen species (ROS). To address these limitations, we engineered the MnO₂@UiO-66(Ce) (abbreviated as MCU) system, which was fabricated through the integration of MnO₂ into nanoscale mesoporous UiO-66 MOFs for OA therapy. Within the MOF architecture, MnO₂ coupled with Ce clusters establishes a continuous superoxide dismutase/catalase cascade reaction platform that enables efficient ROS scavenging. In vitro and in vivo experiments reveal that the MCU system significantly reduces intracellular ROS accumulation and ameliorates the inflammatory microenvironment, consequently attenuating cartilage matrix destruction. Further mechanistic investigations indicates that MCU alleviates OA progression through the epigenetic activation of Wnt/β-catenin via adenosine monophosphate-activated protein kinase-disruptor of telomeric silencing 1-like-mediated H3K79 methylation.
