Despite the correlation of calcification with plaque rupture and sudden death, there are no clinically approved therapies that treat vascular calcification. Notably, vascular smooth muscle cells (VSMCs) represent a promising target to inhibit vascular calcification, as VSMCs are the primary source of calcification deposition in the vasculature. To that end, we report a novel approach using extracellular vesicles (EVs) to deliver anti-osteogenic miR-133 to osteochondrogenic VSMCs in atherosclerosis. Traditionally, loading miRs into EVs is marred by low loading efficiency, inefficient EV modification, miR degradation, or loss of EV structural integrity. To address these challenges, VSMCs were transduced to create cell lines expressing miR-133 modified with ExoMotifs, or 4–8 nucleotide motifs which enable binding to proteins involved in miR sorting, resulting in VSMCs that secrete EVs highly loaded with miR-133. Additionally, EVs were surface functionalized with a hydroxyapatite binding peptide (HABP) to enable targeting to areas of vascular calcification. Our results show that HABP-miR-133-EVs can inhibit osteochondrogenic VSMCs, promote contractile VSMCs genes, and inhibit vascular calcification both <em>in vitro</em> and <em>in vivo</em> in murine atherosclerosis models.

Over the past few decades, even with rapid intraoperative tissue pathology assessment, the overall rate of positive surgical margins for tumors stagnated between 15 % and 60 %. The increased local recurrence rates and poor prognoses associated with various cancers, such as head and neck, brain, breast, lung, prostate, and gastrointestinal cancers, are linked to positive margins. Recently, driven by the concept of precise surgery, significant advancements have been reported in the intraoperative use of fluorescent contrast agents in the field of surgery. Molecular imaging via intraoperative fluorescence plays a guiding role in surgery, providing surgeons with visible fluorescent images. In clinical applications, fluorescent contrast agents can clearly delineate tumor boundaries, offering high recognition capacities and real-time guidance during surgery. Additionally, they can localize lymph node metastases, detect small metastatic lesions, and identify critical anatomical structures during surgery, thus reducing the risk of collateral damage. An ideal surgical guidance technology should lack radiation and display a high sensitivity and good resolution and an adjustable field of view, with rapid imaging. Enhancing the tissue penetration of fluorescence and targeting capacities of molecular probes are critical in providing more comprehensive tumor-related data. Additionally, screening and identifying other tumor biomarkers and more of their corresponding targeted molecular data are essential in enhancing the specificity of molecular imaging. Finally, the investigation and use of a wider range of near-infrared fluorescent dyes with improved biocompatibilities and imaging are critical in designing synthetic probes for application in intraoperative navigation.

Despite advancements in various assembly methods, scalability and cell viability remain challenging due to the time consuming nature of certain approaches. Acoustic assembly has emerged as a powerful technology for modular units' assembly, leveraging sound waves to achieve rapid, contactless spatial arrangement by fine-tuning parameters such as frequency, amplitude, and chamber geometry. Here we present a system that employs acoustic waves to generate spatial patterns of liquid-core microcapsules, encapsulating poly-caprolactone surface-functionalized microparticles and umbilical cord-derived mesenchymal stem cells. The microcapsules were produced using electrohydrodynamic atomization in conjugation with an aqueous two-phase system and subsequently embedded in gelatin methacrylate. Acoustic waves were then applied to assemble the liquid-core microcapsules in well-defined patterns within the hydrogel precursor followed by crosslinking for structural stability. This approach allows us to define spatial patterns with precision, aligning with simulation predictions. The liquid nature of the microcapsules’ core permits the organization of cells within the space towards the formation of microtissues decoupled from the external environment. The patterned constructs maintained cell viability for 14 days, facilitating the formation of microaggregates within liquid-core microcapsules and maintained organized microstructures. To explore the versatility of this system, we successfully patterned and stacked multiple layers of microcapsules, increasing structural complexity. Furthermore, we demonstrated its ability to support co-culture by seeding human umbilical vein endothelial cells onto the constructs as a proof of concept for promoting enhanced cellular interactions. This platform offers a scalable, versatile solution for developing tissue-mimetic multiscale constructs with tunable complexity, enabling rapid and non-contact assembly, making it a valuable tool for advancing in vitro models and studying complex cellular interactions.</div></div>","PeriodicalId":254,"journal":{"name":"Biomaterials","volume":"325 ","pages":"Article 123555"},"PeriodicalIF":12.8,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144654809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
