A study of scarless wound healing through programmed inflammation, proliferation and maturation using a redox balancing nanogel. J Biomed Mater Res A 2024; 112:1594-1611. [PMID: 38545912 DOI: 10.1002/jbm.a.37712] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 03/15/2024] [Accepted: 03/19/2024] [Indexed: 07/12/2024]
Abstract
In the study, we have shown the efficacy of an indigenously developed redox balancing chitosan gel with impregnated citrate capped Mn3O4 nanoparticles (nanogel). Application of the nanogel on a wound of preclinical mice model shows role of various signaling molecules and growth factors, and involvement of reactive oxygen species (ROS) at every stage, namely hemostasis, inflammation, and proliferation leading to complete maturation for the scarless wound healing. While in vitro characterization of nanogel using SEM, EDAX, and optical spectroscopy reveals pH regulated redox buffering capacity, in vivo preclinical studies on Swiss albino involving IL-12, IFN-γ, and α-SMA signaling molecules and detailed histopathological investigation and angiogenesis on every stage elucidate role of redox buffering for the complete wound healing process.

Abstract
Bioactive hydrogels are currently receiving significant attention. In this study, silk fibroin tyramine-modified gelatin hydrogels (SF-TG) with varying degrees of tyramine root substitution were explored. The physicochemical property and biocompatibility of low degree of substitution tyramine-modified gelatin hydrogel (SF-LTG) and high degree of substitution tyramine-modified gelatin hydrogel (SF-HTG) were compared. The results showed that SF-LTG possessed better mechanical property and higher biocompatibility. Thus, SF-LTG was selected as a bioactive matrix and loaded with basic fibroblast growth factor (bFGF); subsequently, curcumin-coupled chitosan rods (CCCRs-EGF) enriched with epidermal growth factor (EGF) were added to obtain SF-LTG-bFGF@CCCRs-EGF hydrogels. The results showed that SF-LTG-bFGF@CCCRs-EGF retained the basic structural and mechanical properties of the SF-LTG matrix gel material and underwent multiple loading and orderly release with different activities while displaying antioxidant, anti-inflammatory, antimicrobial, and pro-cellular proliferation activities and orderly regulation of activity during wound healing. Therefore, the SF-LTG-bFGF@CCCRs-EGF hydrogel is of great value in healing complex wounds.

Abstract
Nanostructured silica-based materials have great potential as drug delivery vehicles for precise and personalized medical applications. As natural nanostructured silica, diatomite biosilica (DB) is recognized as a novel carrier to construct oral/parenteral smart drug delivery systems due to high surface area, biocompatibility, and applicability at low cost, yet the related studies on its use in local delivery routes are still scarce. Herein, we proposed a novel strategy to develop multifunctional nasal drug delivery vehicles based on DB, and demonstrated their versatile performance for enhanced treatment of allergic rhinitis (AR). As a proof of concept, the purified DB microparticles were loaded with budesonide as an anti-inflammatory model drug, and further processed via surface modification to graft polydopamine and carboxymethyl chitosan layers. The synthesized microcapsules exhibited remarkable mucin binding capacity and antibacterial activity against Staphylococcus aureus. Besides, toxicity evaluation with human skin fibroblast cells and hemolysis tests indicated their high biocompatibility. Moreover, in vitro drug release results demonstrated pH-responsive release performance of the microcapsules under simulated AR environment (pH 5.0, 35 °C). Hence, this study provides a facile and reliable approach to construct DB-based mucoadhesive nasal drug delivery vehicles, showing great potential for treatment of allergic airway inflammatory diseases.

Abstract
Electrostatic spinning as a technique for producing nanoscale fibers has recently attracted increasing attention due to its simplicity, versatility, and loadability. Nanofibers prepared by electrostatic spinning have been widely studied, especially in biomedical applications, because of their high specific surface area, high porosity, easy size control, and easy surface functionalization. Wound healing is a highly complex and dynamic process that is a crucial step in the body's healing process to recover from tissue injury or other forms of damage. Single-component nanofibers are more or less limited in terms of structural properties and do not fully satisfy various needs of the materials. This review aims to provide an in-depth analysis of the literature on the use of electrostatically spun nanofibers to promote wound healing, to overview the infinite possibilities for researchers to tap into their biomedical applications through functional composite modification of nanofibers for advanced and multifunctional materials, and to propose directions and perspectives for future research.

Abstract
Multifunctional dressing materials are highly required to combat multidrug resistant bacteria in wound infections. Here an alginate-based aerogel dressing is reported that combines photothermal bactericidal activity, hemostatic property, and free radical scavenging for skin wound disinfection and accelerated wound healing. The aerogel dressing is facilely constructed by immersing a clean nail (Fe) in a mixed solution of sodium alginate (Alg) and tannic acid (TA), followed by freezing, solvent replacement, and air drying. The Alg matrix plays an essential role in modulating the continuous assembly process between TA and Fe to allow the homogenous distribution of TA-Fe metal-phenolic networks (MPN) in the resulting composite, without forming aggregates. The photothermally responsive Nail-TA/Alg aerogel dressing is successfully applied in a murine skin wound model infected with Methicillin-resistant Staphylococcus aureus (MRSA). This work provides a facile strategy to integrate MPN with the hydrogel/aerogel matrix through in situ chemistry, which is promising for developing multifunctional biomaterials and biomedicine.

Abstract
The rapid healing and repair of skin wounds has been receiving much clinical attention. Covering the wound with wound dressing to promote wound healing is currently the main treatment for skin wound repair. However, the performance of wound dressing prepared by a single material is limited and cannot meet the requirements of complex conditions for wound healing. MXene is a new two-dimensional material with electrical conductivity, antibacterial and photothermal properties and other physical and biological properties, which has a wide range of applications in the field of biomedicine. Based on the pathophysiological process of wound healing and the properties of ideal wound dressing, this review will introduce the preparation and modification methods of MXene, systematically summarize and review the application status and mechanism of MXene in skin wound healing, and provide guidance for subsequent researchers to further apply MXene in the design of skin wound dressing.

Abstract
A structurally stable and antibacterial biomaterial used for temporary cranioplasty with guided bone regeneration (GBR) effects is an urgent clinical requirement. Herein, we reported the design of a biomimetic Ag/bacterial cellulose/hydroxyapatite (Ag/BC@HAp) hydrogel mesh with a double-sided functionalized structure, in which one layer was dense and covered with Ag nanoparticles and the other layer was porous and anchored with hydroxyapatite (HAp) via mineralization for different durations. Such a double-sided functionalized design endowed the hydrogel with distinguished antibacterial activities for inhibiting potential infections and GBR effects that could prevent endothelial cells and fibroblasts from migrating to a defected area and meanwhile show biocompatibility to MC3T3-E1 preosteoblasts. Furthermore, it was found from in vivo experimental results that the Ag/BC@HAp hydrogel with 7-day mineralization achieved optimal GBR effects by improving barrier functions toward these undesired cells. Moreover, this BC-based hydrogel mesh showed an extremely low swelling ratio and strong mechanical strength, which facilitated the protection of soft brain tissues without gaining the risk of intracranial pressure increase. In a word, this study offers a new approach to double-sided functionalized hydrogels and provides effective and safe biomaterials used for temporary cranioplasty with antibacterial abilities and GBR effects.

Abstract
As novel wound dressings, cryogels with rapid hemostatic property and good sterilization effect are urgently desirable for wound healing. To reduce the use of antibiotics, antibacterial photothermal therapy with broad-spectrum bactericidal capacity and non-obvious bacterial resistance has been widely researched. However, photothermal agents usually suffer from poor hemostatic ability. In this research, sodium alginate (SA) and epigallocatechin gallate (EGCG) were non-covalently cross-linked in suit by ferric ions to obtain SA/EGCG/Fe (SEF) cryogels after lyophilization as an antibacterial wound dressing. Next, its photothermal performance was intensively assessed. Moreover, its hemostasis and bactericidal effect were evaluated. First, it displayed extraordinary photothermal ability owing to the formation of Fe3+/EGCG-based metal phenolic networks (MPNs) inside the SEF cryogel. Furthermore, in vitro and in vivo assays illustrated that it exhibits rapid hemostatic capacity owing to its high porosity and MPN-mediated cell adhesion capacity. In conclusion, the SEF cryogel manifests satisfactory hemostatic and bactericidal properties. Therefore, it is a promising wound-dressing candidate for clinical applications.

Abstract
Development of rapid and effective hemostatic materials has always been the focus of research in the healthcare field. Nanofibrous materials which recapitulate the delicate nano-topography feature of fibrin fibers produced during natural hemostatic process, offer large length-to-diameter ratio and surface area, tunable porous structure, and precise control in architecture, showing great potential for staunching bleeding. Here we present a comprehensive review of advances in nanofibrous hemostatic materials, focusing on the following three important parts: structural design, fabrication methods, and hemostatic mechanisms. This review begins with an introduction to the physiological hemostatic mechanism and current commercial hemostatic agents. Then, it focuses on recent progress in electrospun nanofibrous hemostatic materials in terms of composition and structure control, surface modification, and in-situ deposition. The article emphasizes the development of three-dimensional (3D) electrospun nanofibrous materials and their emerging evolution for improving hemostatic function. Next, it discusses the fabrication of self-assembling peptide or protein-mimetic peptide nanofibers, co-assembling supramolecular nanofibers, as well as other nanofibrous hemostatic agents. Further, the article highlights the external and intracavitary hemostatic management based on various nanofiber aggregates. In the end, this review concludes with the current challenges and future perspectives of nanofibrous hemostatic materials. STATEMENT OF SIGNIFICANCE: This article reviews recent advances in nanofibrous hemostatic materials including fabrication methods, composition and structural control, performance improvement, and hemostatic mechanisms. A variety of methods including electrospinning, self-assembly, grinding and refining, template synthesis, and chemical vapor deposition, have been developed to prepare nanofibrous materials. These methods provide robustness in control of the nanofiber architecture in the forms of hydrogels, two-dimensional (2D) membranes, 3D sponges, or composites, showing promising potential in the external and intracavitary hemostasis and wound healing applications. This review will be of great interest to the broad readers in the field of hemostatic materials and multifunctional biomaterials.

Abstract
Infection is a huge obstacle to wound healing. Thus, to enhance the healing of infected wounds, wound dressings that permit the dual delivery of antimicrobials and antioxidants are highly desirable. In this study, a series of gelatin-based nanofiber membranes with different curcumin contents were fabricated via solution electrospinning. The obtained membranes were characterized in terms of their morphologies, in addition to their physical, mechanical, and in vitro properties. The results showed that the membranes maintained an integrated morphology, excellent water absorption capability, satisfactory mechanical properties, and a high dissolution rate of curcumin. The addition of curcumin and borneol conferred the membranes the ability to inhibit Staphylococcus aureus and eliminate free radicals. Furthermore, cytocompatibility testing using the L929 cell line confirmed the excellent biocompatibility of the membranes. These gelatin-based nanofiber membranes loaded with curcumin and borneol can therefore be considered as promising materials for dressing wounds. Moreover, the use of biodegradable polymers and environmentally sustainable production techniques in this system render it suitable for the commercial manufacture of composite membranes.

Abstract
Bacteria-related infections are one of the main causes of human skin infections, which are associated with the delay of wound healing and secondary complications. In this work, a series of novel biodegradable films based on thermosensitive carboxymethyl chitin were prepared without using any crosslinkers. All the carboxymethyl chitin films had good flexibility, high transparency, and appropriate water absorption capacity, and could provide a moist environment for wound healing. The silver ions (Ag+) were incorporated on the LTCF-5 film, which had the best mechanical strength (56.39 MPa in the dry state and 0.66 MPa in the wet state) among the carboxymethyl chitin films and was higher than those of the reported biodegradable dressings and commercially available dressings. Compared with the commercial hydrofiber dressing with silver (AQUACEL®), the composite film could provide slow and sustained release of Ag+ with good strength and biodegradability, and displayed excellent long-lasting antibacterial activity in vitro against both S. aureus and E. coli without obvious cytotoxicity, which still possessed good antibacterial activity with almost 100% bacteriostatic rates after soaking in phosphate buffered saline for 7 days. More importantly, the Ag+ loaded carboxymethyl chitin film could promote infected cutaneous wound healing in a S. aureus infected full-thickness cutaneous defect in vivo model because of its long-lasting antibacterial activity, good biocompatibility, exudate absorption and ability to maintain a moist environment. Thus Ag+ loaded carboxymethyl chitin films are excellent candidates for infected wound healing.

Abstract
Excellent mechanical and tissue adhesive properties, long-lasting environmental suitability and reliable biocompatibility are essential factors for the hydrogels to be applied as wound dressing in the clinical fields. Based on the self-assembly micelle structures, a new type of casein micelles (CEs)/polyvinyl alcohol (PVA) GW (glycerol-water) organohydrogel was designed and synthesized by a simple one-pot method. Through a unique "load sharing" effect, the CEs which own suitable adhesion abilities and drug loading capacities simultaneously were embedded into the PVA networks by rich hydrogen bonds, so that to obtain the composite organ hydrogel with not only excellent adhesive abilities, but also enhanced mechanical properties. Benefited from the unique GW binary solvent system, the organohydrogel showed long-lasting moisture lock-in capacity and extreme temperature tolerance (in the range of --20 °C ~ 60 °C). Particularly, after loading the model antibacterial drugs (allicin) within the CEs, the as-developed CEs/PVA GW gel exhibited a prominent long-lasting (>100 h) antibacterial properties (>90%). Furthermore, the organohydrogel was confirmed with prominent biocompatibility to support fibroblast cell proliferation and migration. This work proposed a new strategy to build CEs-based gel system, which have a great potential application in terms of prevent bacterial infection, accelerate tissue proliferation and wound healing.

Abstract
The healing mechanism of diabetic foot wounds is very complicated, and it is difficult for a single-function medical dressing to achieve good therapeutic effects. We propose a simple coaxial biological 3D printing technology, which uses one-step 3D deposition to continuously produce multifunctional medical dressings on the basis of core-shell hydrogel fibers. These dressings have good biocompatibility, controlled drug-release performance, excellent water absorption and retention, and antibacterial and anti-inflammatory functions. In vivo experiments with type 2 diabetic rats were performed over a 14-day period to compare the performance of the multifunctional 3D dressing with a gauze control; the multifunctional 3D dressing reduced inflammation, effectively increased the post-healing thickness of granulation tissue, and promoted the formation of blood vessels, hair follicles, and highly oriented collagen fiber networks. Therefore, the proposed multifunctional dressing is expected to be suitable for clinical applications for healing diabetic foot wounds.
