Abstract Background Magnesium ions play crucial roles in maintaining cellular functions. Research has shown that Mg2+ can promote angiogenesis, indicating its potential for treating cardiovascular ischemic diseases. However, conventional intravenous or oral administration of presents several challenges, including the risk systemic side effects, diminished bioavailability, and a lack targeted delivery mechanisms. In this study, we designed Mg2+-releasing adhesive tissue patch (MgAP) enables dural release ions. Methods A novel was developed on basis ionic crosslinking. Fourier transform infrared spectroscopy confirmed chemical structure, whereas rheological analysis demonstrated stable mechanical properties adaptability to dynamic loads. Sustained quantified over 7 days by inductively coupled plasma–mass spectrometry. rat acute myocardial infarction model, performed echocardiography strain assess cardiac function histological staining evaluate adverse remodeling. We also verified proangiogenic effect through vitro tube formation vivo immunofluorescence assays. Furthermore, transcriptomics Western blotting were explore underlying mechanism. Additional assessments carried out model lower limb ischemia. Results Compared with magnesium chloride, MgAP application effectively improved reduced remodeling model. The left ventricular ejection fraction increased 20.3 ± 6.6%, radial 27.4 4.1%. fibrosis area cell apoptosis rate decreased 10.9 1.2% 32.1 5.5%, respectively. RNA sequencing highlighted upregulation genes related electrophysiological properties, structural functional intercellular connections, revascularization. gap junction protein expression restored local blood supply could contribute repair process posttreatment. observed ischemia Conclusions above results revealed convincing vascular regeneration an ion therapy-based hydrogel, which enabled tissue, aiding repair.

This study developed an alginate, gelatin, and chondroitin sulfate hydrogel incorporating silicon oxide nanoparticles to assess morphology, cell proliferation, viability. The effectiveness of these hydrogels for cartilage repair was evaluated in vivo using male albino rabbits, divided into three groups: a control group without hydrogels, observer with lacking nanoparticles, treatment nanoparticle-enhanced post-injury repair. At 15, 30, 60 days post-surgery, the rabbits were humanely euthanized, excised tissue samples fixed 10% formalin histopathological analysis, then processed embedded paraffin microscopic evaluation. Statistical analysis performed SPSS software ANOVA Tukey's post hoc test. Results indicated that supported viability encouraged differentiation chondrocyte-like phenotypes. Scanning Electron Microscopy (SEM) confirmed hydrogels' porosity showed significant differences survival rates compared group, underscoring potential engineering regenerative strategies.

We herein demonstrate the utility of gelatin methacryloyl (GelMA)/poly(ethylene glycol) diacrylate (PEGDA)-cerium oxide (CeO2) hydrogel inks for manufacturing scaffolds with antimicrobial efficacy by vat photopolymerization. For uniform blending GelMA/PEGDA hydrogels, CeO2 nanoparticles a round shape were synthesized precipitation method coupled calculation at 600 °C. In addition, they had highly crystalline phases and desired chemical structures (oxidation states Ce3+ Ce4+) required outstanding efficacy. A range GelMA/PEGDA-CeO2 different contents (0% w/v, 0.1% 0.5% 1% 5% w/v respect to distilled water content) manufactured. The photopolymerization behavior, mechanical properties, biological properties (swelling biodegradation behaviors) characterized optimize content. produced highest content (5% w/v) showed reasonable (compressive strength = 0.56 ± 0.09 MPa compressive modulus 0.19 0.03 MPa), high swelling ratio (1063.3 10.9%), rate (remaining weight after 28 days 39.6 2.3%). Furthermore, (the number colony-forming units 76 44.6 (×103)). macroporous tightly controlled porous could be manufactured

Pancreatitis is a prominent and severe type of inflammatory disorder that has grabbed lot scientific clinical interest to prevent its onset. It should be detected early avoid the development serious complications, which occur due long-term damage pancreas. The accurate measurement biomarkers are released from pancreas during inflammation essential for detection treatment patients with acute chronic pancreatitis, but this sub-optimally performed in clinically relevant practices, mainly complexity procedure cost treatment. Clinically available tests pancreatitis often time-consuming. also relates disorders exocrine pancreas, such as cystic fibrosis hereditary form fibrosis-like syndrome acquired genetic symptoms can correlated overexpression specific markers creatinine biological fluids like urine. In review, we studied how develop minimally invasive system using hydrogel-based biosensors, highly absorbent biocompatible polymers respond stimuli enzymes, pH, temperature, or presence biomarkers. These biosensors helpful real-time health monitoring medical diagnostics since they translate reactions into quantifiable data. This paper sheds light on possible use Ayurvedic formulations along hydrogels strategy. analytical devices used enhance real time.

The prevalence of heart valve disease (HVD) has escalated worldwide, because population aging. Currently, artificial replacement is considered the most effective treatment for HVD. complexity and risk have been markedly reduced with development minimally invasive interventional techniques, which resulted in more widespread implantation bioprosthetic valves (BHVs); however, they still present defects including thrombosis, poor cytocompatibility, immune responses, calcification, reduces their service life. We developed a microenvironment-responsive zwitterionic glycocalyx-mimetic hydrogel-engineered BHV (Hes@HS-PP) profile on-demand drug release. Inspired by structure function glycocalyx on inner wall blood vessels, hydrogel coating was covalently constructed photoinduced polymerization. This significantly resisted fouling components thrombosis improved endothelialization potential biocompatibility BHVs shielding interactions between xenogeneic collagenous matrix. Following introduction dynamic borate ester bonds into hydrogel, anti-inflammatory hesperidin (Hes) loaded onto BHVs. Excess reactive oxygen species were scavenged, Hes released inflammatory region demand to achieve regulation ameliorate reactions Moreover, Hes@HS-PP exhibited lower degree calcification rat subcutaneous model. In summary, construction hydrogels enhanced antithrombotic, anti-inflammatory, endothelialization, anticalcification properties mitigated structural valvular degradation, offering new perspectives functional modification

Abstract Skin aging, trauma, and congenital diseases lead to tissue defects functional loss. Effective regeneration remains challenging due limited material bioactivity inadequate consideration of mechanical cues. This study develops a hydrogel integrating human extracellular matrix‐like collagen (hCol) derived from induced adipose mesenchymal stem cells (hASCs) with hyaluronic acid (HA) polyethylene glycol diamine (PEGDA), engineered achieve modulus (≈1 kPa) representative subcutaneous soft tissue. The hCol, produced at scale, provides essential biochemical signals, which, in conjunction the properties, synergistically modulate immune responses, cellular differentiation, anti‐aging processes. Both animal experiments clinical trials validate regenerative efficacy hydrogels. Clinical therapy for mandibular retrognathia shows rapid sustained improvements, repair rates 95.2% 3 months 76.2% 6 months. These findings underscore hydrogel's ability reshape microenvironment, supporting immediate regeneration, while offering promising platform future biomaterial development engineering.

Osteoarthritis (OA), a chronic joint disease affecting over 500 million individuals globally, is characterized by the destruction of articular cartilage and inflammation. Conventional treatments are insufficient for repairing damaged tissue, necessitating novel therapeutic approaches. Mesenchymal stem cells (MSCs), with their potential differentiation self-renewal, hold great promise as treatment OA. However, challenges such MSC viability apoptosis in ischemic environment hinder effectiveness. Hydrogels biocompatibility degradability offer three-dimensional scaffold that support cell differentiation, making them ideal delivery OA treatment. This review discusses pathological features OA, properties MSCs, associated therapy, methods hydrogel preparation functionalization. Furthermore, it highlights advantages hydrogel-based systems while providing insights into future research directions clinical this approach.
