Collagen-based biomimetic scaffolds offer a promising avenue for corneal regeneration. However, the impact of collagen's hierarchical architecture on scaffold properties and its role in corneal healing remains incompletely understood. In this study, we systematically compared two distinct high-density collagen membranes: a fibrous collagen membrane (FCM), fabricated <i>via</i> thermally controlled vitrification to induce collagen self-assembly, and a non-fibrous collagen membrane (NFCM), prepared by chemical crosslinking followed by vitrification drying. The FCM dried at 37 °C exhibited well-aligned collagen fibrils and lamellar organization, along with thermal stability, hydration capacity, and mechanical behavior closely resembling those properties of the native cornea. In contrast, the NFCM, while mechanically brittle, possessed a smooth surface that markedly promoted epithelial cell migration. Leveraging these distinct properties, we constructed a bilayer collagen composite comprising an upper NFCM layer and a lower FCM layer, designed to synergistically facilitate rapid epithelial wound closure and robust stromal integration, respectively. Our findings underscore the pivotal role of collagen microstructure in determining the mechanical, optical, and biological performance of corneal scaffolds, and provide a rational design strategy for developing hierarchically structured collagen membrane composites with translational potential for corneal repair.</p>","PeriodicalId":65,"journal":{"name":"Biomaterials Science","volume":" ","pages":""},"PeriodicalIF":6.1,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149100924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional intravesical drug instillation requires repeated hospital visits and urethral catheterization, which may reduce patient compliance owing to discomfort, urethral trauma, and an increased risk of urinary tract infections. Therapeutic performance is further compromised by rapid drug dilution, frequent bladder emptying, and the dynamic urinary environment, resulting in a short intravesical residence time. Biological barriers, including the exceptionally tight urothelial permeability barrier (transepithelial electrical resistance >10 000 Ω cm²), comparable to the blood-brain barrier, and the hypoxic tumour microenvironment, further restrict drug penetration, leaving less than 5% of the administered dose available at the tumour site. Escalating drug concentrations to compensate for poor penetration frequently results in chemical cystitis and other local adverse effects. Among emerging biomaterials, chitosan has attracted considerable attention owing to its excellent mucoadhesive properties, transient modulation of urothelial tight junctions, favourable biocompatibility, and biodegradability, making it an attractive platform for prolonged intravesical drug retention. Genipin has emerged as the most widely investigated natural crosslinker because of its low cytotoxicity, tunable crosslinking properties, and ability to improve the mechanical stability and sustained-release behaviour of chitosan hydrogels. Integration of ultrasound as a non-invasive external stimulus, particularly through microbubble-mediated cavitation and sonoporation, further enables spatiotemporally controlled drug release and enhanced urothelial permeability. In this review, we critically discuss the biological barriers to intravesical drug delivery and highlight recent advances in ultrasound-responsive chitosan-genipin hydrogels as multifunctional platforms for NMIBC therapy. We evaluate crosslinker safety, strategies for overcoming tumour hypoxia, and preclinical evidence demonstrating prolonged bladder retention (>72 h), 2-3-fold enhanced tissue penetration, and tumour inhibition of 60-80%. Finally, we discuss key translational challenges, including scalable manufacturing, regulatory considerations, patient heterogeneity, and long-term safety, while outlining future opportunities in theranostic hydrogels, microrobots, closed-loop drug delivery, and multi-stimuli-responsive biomaterials. Collectively, ultrasound-responsive chitosan-genipin hydrogels represent a promising intravesical platform capable of enhancing therapeutic efficacy while minimizing treatment-related toxicity in NMIBC.</p>","PeriodicalId":65,"journal":{"name":"Biomaterials Science","volume":" ","pages":""},"PeriodicalIF":6.1,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149078986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the important role of TNTs and macrophages in cancer, the role of macrophage-induced TNTs in the co-delivery of metformin (MET) and the chemotherapeutic drug doxorubicin (DOX) in mediating drug resistance is not fully understood. In this study, the inhibition of TNT-mediated breast cancer progression was mechanistically explored through DOX/MET co-delivery. For cargo delivery, the co-drugs were loaded onto gelatin and gum acacia. The DOX/MET co-loaded nanohydrogel induced the most substantial reduction in cell viability in MCF-7 breast cancer cells. The combination of DOX-MET resulted in the robust activation of caspase-3, indicating the enhanced execution of apoptosis. Upon internalization and lysosomal release, MET activates AMPK signaling, which in turn suppresses the PI3K/AKT/mTOR axis and inhibits TNT formation, thereby blocking intercellular communication. Concurrently, DOX localizes to the nucleus, where it disrupts DNA replication and directly induces cytotoxicity. This combined approach not only targets proliferative capacity but also dismantles cellular networking mechanisms. Overall, the results of this study endorse that this combined therapeutic strategy might offer enhanced efficacy in limiting breast cancer progression and metastasis through the inhibition of TNTs.</p>","PeriodicalId":65,"journal":{"name":"Biomaterials Science","volume":" ","pages":"5170-5185"},"PeriodicalIF":6.1,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148756944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rise in extracellular Ca²⁺ ions by mast cells and platelets, which acts as a death signal for neuronal cells, plays a crucial role in the pathogenesis of the disease. Both cell types produce the neurotransmitters histamine and serotonin and express the <i>N</i>-methyl-D-aspartate (NMDA) receptor on their surface. Here, we show that the physiological inorganic polymer polyphosphate (Na-polyP; when administered as the sodium salt), which is stored and released by platelets, can suppress the adverse effects in atopic dermatitis due to its unique ability to bind Ca²⁺ by coacervate formation. This eliminates the Ca²⁺ burst occurring in neural tissue damage by exchanging Na⁺ for Ca²⁺ ions. It is shown that the energy-rich Na-polyP, with a physiological chain length of approximately 50 phosphate residues, enhances the serotonin-induced neurite outgrowth in neuronal PC12 cells, even in the absence of the neurotransmitter and additional Ca²⁺ ions. In rat primary neuronal cells, Na-polyP completely prevented the histamine-caused apoptotic cell death. Based on the results of experiments with the indicator Fura 2-AM, which demonstrated an abolition of the histamine- and glutamate-induced rise in intracellular Ca²⁺ levels in neurons after addition of Na-polyP, we conclude that the neuroprotective effect of Na-polyP is due to the formation of polyP coacervate through Na⁺/Ca²⁺ exchange. Furthermore, it was found that Na-polyP enhances collagen fibrillogenesis, which is impaired in atopic dermatitis, as demonstrated by immunostaining and RT-qPCR experiments using human endothelial cells (HUVEC). The role of disease-relevant metalloproteinases induced by polyP was demonstrated in experiments with the inhibitor quercetin, using CD80 as a marker for pro-inflammatory M1 macrophages.
