This union of biomacromolecules merges the extracellular matrix functionality of collagen with the designable bioactivity of nucleic acids, enabling advances in regenerative medicine, tissue engineering, gene delivery, and targeted therapy. This review traces the historical foundations and critical applications of DNA-collagen complexes and highlights their capabilities, demonstrating them as biocompatible, bioactive, and tunable platform materials. These complexes form structures across length scales, including nanoparticles, microfibers, and hydrogels, a process controlled by the relative amount of each component and the type of nucleic acid and collagen. The broad distribution of different types of collagen within the body contributes to the extensive biological relevance of DNA-collagen complexes. Functional nucleic acids can form these complexes, such as siRNA, antisense oligonucleotides, DNA origami nanostructures, and, in particular, single-stranded DNA aptamers, often distinguished by their rapid self-assembly at room temperature and formation without external stimuli and modifications. The simple and seamless integration of nucleic acids within collagenous matrices enhances biomimicry and targeted bioactivity, and provides stability against enzymatic degradation, positioning DNA-collagen complexes as an advanced biomaterial system for many applications including angiogenesis, bone tissue regeneration, wound healing, and more.","PeriodicalId":8,"journal":{"name":"ACS Biomaterials Science & Engineering","volume":" ","pages":"1253-1268"},"PeriodicalIF":5.4,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11897955/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143044854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nano-drug delivery systems can serve as drug carriers to enhance drug delivery, addressing these challenges with improved efficacy and reduced adverse effects. In this study, a microfluidic swirl mixer is used to prepare silk fibroin composite nanoparticles containing ASC-J9 and copper sulfate (CuS), and the effects of different process parameters on silk fibroin nanoparticles (SNPs) were explored and optimized. The synthesized composite ASC-J9-CuS@SNPs exhibited a mean particle diameter of 180 ± 10 nm and PDI of 0.20 ± 0.03. Two-dimensional/three-dimensional (2D/3D) cell experiments showed that the composite nanomaterials have excellent biocompatibility and antitumor activity with a noticeable cancer cell specificity. In vivo experiments showed that ASC-J9-CuS@SNPs effectively controlled tumor growth without causing damage to blood cells and vital organs.

In recent years, most studies have emphasized the crucial role of the gut-kidney axis in the pathogenesis of IgA nephropathy, and the ileal Peyer patches in the intestinal mucosal immune system are the main site for IgA production. Therefore, in this study, hydroxychloroquine (HCQ) and dexamethasone (DXM) were used as model drugs, and yeast cell wall (YCW)-coated oleic acid-grafted chitosan (CSO) was used as a carrier to construct a yeast cell wall oral drug delivery system HCQ/DXM@CSO@YCW. This delivery system achieves ileal targeted delivery through the yeast cell wall (YCW), reduces IgA production, and synergistically regulates the inflammatory pathological environment. The delivery system had good gastrointestinal stability and biocompatibility. In vitro cell experiments had shown the targeted uptake ability of dendritic cells and macrophages, and in vitro intestinal experiments showed that the YCW has ileal targeting properties. In vivo pharmacodynamic experiments showed that the HCQ/DXM@CSO@YCW delivery system could significantly reduce the serum IgA levels and IgA deposition in the renal tissue of IgAN mice, as well as the levels of IL-6, TNF-α, and TGF-β in the renal tissue, improving the pathological morphology of the renal tissue.

Despite their advantages, conventional NF membranes often encounter issues in transmigration assays due to their transparency, which leads to overlapping fluorescent signals from transmigrated and nontransmigrated cells. This overlap complicates the clear differentiation between these cell populations, making the quantitative evaluation of live-cell transmigration challenging. To address this issue, we developed a light-blocking nanofiber (LB-NF) membrane by incorporating carbon black into polycaprolactone NFs. This LB-NF membrane is designed not only to mimic the biophysical properties of the basement membrane but also to enable in situ analysis of transmigrated cells through its light-blocking properties. Our study demonstrated the effectiveness of the LB-NF membrane in a transmigration assay using human brain cerebral microvascular endothelial cells (HBEC-5i), enabling physiologically relevant cell transmigration while significantly enhancing the accuracy of in situ fluorescence detection. Furthermore, drug testing within a choroidal neovascularization model using the LB-NF membrane underscores its utility and potential impact on pharmaceutical development, particularly for diseases involving abnormal cell transmigration. Therefore, the developed LB-NF membrane represents a valuable tool for the precise assessment of in situ cellular transmigration and holds significant promise for advancing drug screening and therapeutic development.","PeriodicalId":8,"journal":{"name":"ACS Biomaterials Science & Engineering","volume":" ","pages":"1834-1846"},"PeriodicalIF":5.4,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its therapeutic outcomes have remained unsatisfactory due to severe side effects, a short elimination half-life, the emergence of drug resistance, and the induction of metastasis. Combination with other chemotherapeutic agents has been proposed as one strategy to address the drawbacks of CDDP-based therapy. Therefore, this study aimed to boost the antitumor efficacy of cisplatin (CDDP) with a PI3K/mTOR dual inhibitor, dactolisib (BEZ), via a carrier-free codelivery system based on the self-assembly of the coordinated CDDP-BEZ. The synthesized CDDP-BEZ nanoparticles (NPs) possess sensitive pH-responsiveness, facilitating the delivery of both drugs to cancer cells. CDDP-BEZ NPs specifically enhanced cytotoxicity in cancer cells due to the synergy between cisplatin and dactolisib, resulting in augmented DNA damage, activation of mitochondria-dependent apoptosis, and increased inhibition on the PI3K/mTOR signaling axis. The inhibition of tumor migration and metastasis by CDDP-BEZ NPs was observed both in vitro and in vivo. Our data suggest that CDDP-BEZ NPs could serve as a safe and effective platform to maximize the synergy between both drugs in combating cancer, presenting a strategy to promote the therapeutic efficacy of platinum-based chemotherapeutic agents by combining them with PI3K inhibitors.","PeriodicalId":8,"journal":{"name":"ACS Biomaterials Science & Engineering","volume":" ","pages":"1456-1471"},"PeriodicalIF":5.4,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11897951/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerous techniques described in the literature aim to provide diverse mechanical and topographical cues simultaneously, fostering enhanced in vitro cardiac maturation and functionality. Among these, cellulose paper-based scaffolds have gained attention owing to their inherent benefits, such as biocompatibility and ease of chemical and physical modification. This study introduces a novel approach of utilizing customized paper-based scaffolds as cell culture substrates, facilitating both the formation and manipulation of cell constructs while promoting mechanical contraction. Here, we investigated two methodologies to foster mechanical contractions of paper-based constructs: the incorporation of micropatterns on paper to dictate cell orientation and macropattern created by the origami-folded paper. Both approaches provide mechanical support and foster cardiac functionality. However, while micropatterning does not significantly improve the functional parameters, a macropattern created by origami folding proves to be essential in facilitating contraction of the paper-based cardiac constructs. Furthermore, we provide proof of principle for the combination with a layer of physiologically differentiated microvascular networks. This approach holds great promise for the development of structurally organized contractile cardiac tissues with the possibility of creating multistrata of cardiac and vascular layers to promote in vivo cell survival and function beyond what is typically achieved in conventional cell culture.","PeriodicalId":8,"journal":{"name":"ACS Biomaterials Science & Engineering","volume":" ","pages":"1583-1597"},"PeriodicalIF":5.4,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11897953/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies have focused on developing hydrogels with self-healing properties that can autonomously recover their structural integrity and mechanical properties after damage. These hydrogels, formed through dynamic covalent reactions, exhibit superior biocompatibility, mechanical strength, and responsiveness to stimuli, particularly pH changes. However, conventional hydrogels are limited by their weak and brittle nature. To address this, ionizable moieties within polyelectrolytes can be tuned to create ionically cross-linked hydrogels, leveraging natural polymers such as alginate, chitosan, hyaluronic acid, and cellulose. The integration of ionic liquids into these hydrogels enhances their mechanical properties and conductivity, positioning them as significant self-healing agents.

Here, we developed a stiffness-tunable hydrogel-based three-dimensional system that recapitulates the extracellular matrix and physiological properties of human breast cancer in vitro. Adjusting the ratio of GelMA to PEGDA in the hydrogel formulation enabled the fine-tuning of matrix stiffness across a range of 7 to 52 kPa. Utilizing this three-dimensional (3D) hydrogel platform for a breast cancer cell culture has enabled precise functional evaluations. Variations in matrix stiffness resulted in significant changes in the morphology of breast cancer cells after 2 weeks of incubation. The analysis of transcriptomic sequencing revealed that the 3D microenvironment significantly changed the expression of a wide panel of transcriptomic profiles of breast cancer cells in various matrix stiffness. Gene Ontology analysis further suggested that specific biological functions could potentially be linked to the magnitude of the matrix stiffness. According to our findings, extracellular matrix rigidity modulates the sensitivity of breast cancer cells to paclitaxel and adriamycin. Notably, the expression of ABCB1 and YAP1 genes may be upregulated in the 3D culture environment, potentially contributing to the increased drug resistance observed in breast cancer cells.

To tackle these issues, we used hydroxypropyl trimethylammonium chloride chitosan (HACC) and gallic acid-modified gelatin (GAG) to create extracellular matrix (ECM) coatings on titanium using layer-by-layer self-assembly. GAG showed better water solubility at room temperature, being over 99.0 times more soluble than regular gelatin.
