In this procedure, the commonly used materials have a short retention time and a limited lifting capacity, which will prolong the duration of the ESD procedure. Furthermore, these liquids tend to diffuse after ESD surgery, failing to adequately protect the wound. Therefore, we designed and developed injectable hydrogels based on hyaluronic acid. A series of oxidized hyaluronic acid (OHA) and hydrazide hyaluronic acid (AHA) were synthesized, and 16 kinds of injectable hydrogels were fabricated to investigate the effects of molecular structures on the properties of the hydrogels. Among these, the O1A3 hydrogel exhibited a suitable injection performance, gelation time, and mechanical properties, along with good blood and cell compatibility <i>in vitro</i>. Subsequently, in a porcine model of the ESD procedure, the results demonstrated that the O1A3 hydrogel exhibited a good retention time and lifting performance while also significantly reducing the operation time from 1–2 h to ∼10 min. Furthermore, the adhesive property of the O1A3 hydrogel on small bleeding spots and wounds could be observed, which was beneficial in protecting the wound from the complex environment of the gastrointestinal tract. The present work of injectable hyaluronic acid-based hydrogels could be promising to improve the efficiency of ESD surgery.</p>","PeriodicalId":8,"journal":{"name":"ACS Biomaterials Science & Engineering","volume":"10 12","pages":"7657–7666 7657–7666"},"PeriodicalIF":5.4,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142843214","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, their efficacy is restricted by the insufficient cross-presentation of cell membrane-associated antigens. Saposins (SAs), which are vital for membrane vesicle disintegration and cell membrane-associated antigen presentation, are severely deficient in the antigen-presenting cells (APCs) within tumors. Herein, we propose a complementary strategy for increasing the efficacy of biomimetic nanovaccines via the use of SAs. Biomimetic nanovaccines were designed using cancer cell membrane shells to provide a comprehensive array of tumor-associated antigens and reactive oxygen species (ROS)-responsive nanoparticle cores that allowed the codelivery of cytosine–guanine dinucleotides (CpGs) and SAs. The biomimetic nanovaccines were ROS-responsive and highly internalized by APCs, which enabled the release of CpGs and SAs in the endo/lysosomes of APCs. Furthermore, biomimetic nanovaccines increased the activation of immunosuppressive APCs and enhanced T-cell priming by delivering SAs to the APCs. Consequently, biomimetic nanovaccines loaded with SAs not only suppressed tumor growth but also exhibited excellent therapeutic effects in combination with immune checkpoint blockade strategies. Overall, our study provides insights into the development of enhanced biomimetic nanovaccines via integrating SAs and offers a promising strategy for highly effective cancer immunotherapy.</p>","PeriodicalId":8,"journal":{"name":"ACS Biomaterials Science & Engineering","volume":"10 12","pages":"7482–7491 7482–7491"},"PeriodicalIF":5.4,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142843224","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}

Although the regulation of chemoresistance through biochemical signaling is well-documented, the influence of three-dimensional (3D) matrix stiffness is poorly understood. In this study, gelatin methacrylate (GelMA) hydrogels were reconstructed with stiffnesses spanning the range from normal to cancerous PDAC tissues, which are termed as the soft group and stiff group. The PDAC cell lines (Mia-PaCa2 and CFPAC-1) encapsulated in the stiff group displayed a chemoresistance phenotype and were prominent against gemcitabine. RNA-sequencing and bioinformatics analysis indicated that glycolysis was apparently enriched in the stiff group <i>versus</i> the soft group, which was also validated through assays of glucose uptake, lactate production, and the expression of GLUT2, HK2, and LDHA. A rescue assay with 2-deoxy-<span>d</span>-glucose and <i>N</i>-acetylcysteine demonstrated that glycolysis is involved in chemoresistance. Furthermore, the expression of Piezo1 and the content of Ca<sup>2+</sup> were elevated in the stiff group. The addition of Yoda1 (Piezo1 agonist) in the soft group promoted glycolysis, whereas in the stiff group, treatment with GsMTx4 (Piezo1 inhibitor) inhibited glycolysis, which showcased that Piezo1 participated in 3D matrix stiffness-induced glycolysis. Taken together, Piezo1-mediated glycolysis was involved in PDAC chemoresistance triggered by the 3D matrix stiffness.

However, these synthetic substrates are often costly and complex to use, leading many laboratories to continue using simpler undefined extracellular matrix (ECM) protein mixtures. In this study, we present a method using poly(norepinephrine) (pNE) for surface modification to enhance the immobilization of ECM proteins on various substrates, including polydimethylsiloxane (PDMS) and ultralow attachment (ULA) hydrogels, thereby supporting hPSC culture and maintenance of pluripotency. The pNE-mediated surface modification enables spatial patterning of ECM proteins on nonadhesive ULA surfaces, facilitating tunable macroscopic cell patterning. This approach improves hPSC attachment and growth and allows for cell patterning to study the effects of anisotropic environments on the hPSC fate.

We employed the well-developed SpyTag and SpyCatcher chemistry to engineer PhoCl-containing covalently cross-linked hydrogels. In the hydrogel network, PhoCl, which can be cleaved into two fragments upon violet irradiation, is employed as a dynamic structural motif to regulate the cross-linking density of the hydrogel network. The resultant PhoCl-containing hydrogels showed photoresponsive viscoelastic properties. Upon violet irradiation, the PhoCl hydrogels soften, leading to an irreversible reduction in the storage moduli. However, no gel–sol transition was observed. Leveraging this light-induced stiffness change, we employed this hydrogel as a cell culture substrate to investigate the mechanobiological response of NIH-3T3 fibroblast cells. Our results showed that 3T3 cells can change their morphologies in response to the stiffness change of the PhoCl hydrogel substrate dynamically, rendering PhoCl-based hydrogels a useful substrate for other mechanobiological studies.</p>","PeriodicalId":8,"journal":{"name":"ACS Biomaterials Science & Engineering","volume":"10 12","pages":"7404–7412 7404–7412"},"PeriodicalIF":5.4,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142850170","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}

Biofilms exhibit increased resistance to antimicrobials relative to single planktonic cells, emphasizing the need for effective biofilm removal during periodontal therapy for peri-implantitis treatment. To tackle this issue, our team evaluated the effectiveness of low-temperature plasma (LTP) for disinfecting titanium discs contaminated with multispecies biofilms associated with peri-implantitis, specifically focusing on biofilms matured for 14 and 21 days as well as biofilms that had formed on Straumann<sup>Ⓡ</sup> Ti-SLA implants for 21 days. The biofilms included <i>Actinomyces naeslundii</i>, <i>Porphyromonas gingivalis</i>, <i>Streptococcus oralis</i>, and <i>Veillonella dispar</i>, which were grown in anaerobic conditions. These biofilms were subjected to LTP treatment for 1, 3, and 5 min, using distances of 3 or 10 mm from the LTP nozzle to the samples. Control groups included biofilms formed on Ti discs or implants that received no treatment, exposure to argon flow at 3 or 10 mm of distance for 1, 3, or 5 min, application for 1 min of 14 μg/mL amoxicillin, 140 μg/mL metronidazole, or a blend of both, and treatment with 0.12% chlorhexidine (CHX) for 1 min. For the implants, 21-day-old biofilms were treated with 0.12% CHX 0.12% for 1 min and LTP for 1 min at a distance of 3 mm for each quadrant. Biofilm viability was assessed through bacterial counting and confocal laser scanning microscopy. The impact of LTP was investigated on reconstituted oral epithelia (ROE) contaminated with <i>P. gingivalis</i>, evaluating cytotoxicity, cell viability, and histology. The results showed that a 1 min exposure to LTP at distances of 3 or 10 mm significantly lowered bacterial counts on implants and discs compared to the untreated controls (<i>p</i> &lt; 0.017). LTP exposure yielded lower levels of cytotoxicity relative to the untreated contaminated control after 12 h of contamination (<i>p</i> = 0.038), and cell viability was not affected by LTP (<i>p</i> ≥ 0.05); thus, LTP-treated samples were shown to be safe for tissue applications, with low cytotoxicity and elevated cell viability post-treatment, and these results were validated by qualitative histological analysis. In conclusion, the study’s results support the effectiveness of 1 min LTP exposure in successfully disinfecting mature peri-implantitis multispecies biofilms on titanium discs and implants.
