[PMID: 33919848 PMCID: PMC8070826 DOI: 10.3390/ph14040362] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Revised: 04/09/2021] [Accepted: 04/13/2021] [Indexed: 12/14/2022] Open
Abstract
The aim of this review is to present 3D bioprinting of skin substitutes as an efficient approach of managing skin injuries. From a clinical point of view, classic treatments only provide physical protection from the environment, and existing engineered scaffolds, albeit acting as a physical support for cells, fail to overcome needs, such as neovascularisation. In the present work, the basic principles of bioprinting, together with the most popular approaches and choices of biomaterials for 3D-printed skin construct production, are explained, as well as the main advantages over other production methods. Moreover, the development of this technology is described in a chronological manner through examples of relevant experimental work in the last two decades: from the pioneers Lee et al. to the latest advances and different innovative strategies carried out lately to overcome the well-known challenges in tissue engineering of skin. In general, this technology has a huge potential to offer, although a multidisciplinary effort is required to optimise designs, biomaterials and production processes.

Abstract
PURPOSE This study aimed to elaborate a hydrogel constituted by carboxymethyl chitosan (CMC), hyaluronic acid (HA) and silver (Ag) and to evaluate its healing effect on partial-thickness burn wounds experimentally induced in rats. METHODS CMC was obtained by chitosan reacting with monochloroacetic acid. The carboxymethylation was confirmed by Fourier-transform infrared spectroscopy and hydrogen nuclear magnetic resonance (NMR). Scanning electron microscopy was used to determine the morphologicalcharacteristics of chitosan and CMC. After the experimental burn wound induction, the animals (n = 126) were treated with different CMC formulations, had their occlusive dressings changed daily and were followed through 7, 14 and 30 days. Morphometric, macroscopic and microscopic aspects and collagen quantification were evaluated. RESULTS Significative wound contraction, granulation tissue formation, inflammatory infiltration and collagen fibers deposit throughout different phases of the healing process were observed in the CMC hydrogels treated groups. CONCLUSIONS The results showed that, in the initial phase of the healing process, the most adequate product was the CMC/HA/Ag association, while in the other phases the CMC/HA association was the best one to promote the healing of burn wounds.

Abstract
Chitosan is a natural polymer that can sustain not only osteoblast adhesion and proliferation for bone regeneration purposes, but it is also claimed to exhibit antibacterial properties towards several Gram-positive and Gram-negative bacteria. In this study, chitosan was modified with sodium hyaluronate, crosslinked with polyethylene glycol diglycidyl ether (PEGDE) and both osteoblast cytotoxicity and antibacterial behavior studied. The presence of sodium hyaluronate and PEGDE on chitosan was detected by FTIR, XRD, and XPS. Chitosan (CHT) films with sodium hyaluronate crosslinked with PEGDE showed a better thermal stability than pristine hyaluronate. In addition, osteoblast cytocompatibility improved in films containing sodium hyaluronate. However, none of the films exhibit antimicrobial activity against Escherichia coli, Enterococcus faecalis, and Staphylococcus aureus while exhibiting low to mild activity against Salmonella typhimurion.

Abstract
Introduction: Years of tissue engineering research have clearly demonstrated the potential of integrating growth factors (GFs) into scaffolds for tissue regeneration, a concept that has recently been applied to wound dressings. The old concept of wound dressings that only take a passive role in wound healing has now been overtaken, and advanced dressings which can take an active part in wound healing, are of current research interest.Areas covered: In this review we will focus on the recent strategies for the delivery of GFs to wound sites with an emphasis on the different approaches used to achieve fine tuning of spatial and temporal concentrations to achieve therapeutic efficacy.Expert opinion: The use of GFs to accelerate wound healing and reduce scar formation is now considered a feasible therapeutic approach in patients with a high risk of infections and complications. The integration of micro - and nanotechnologies into wound dressings could be the key to overcome the inherent instability of GFs and offer adequate control over the release rate. Many investigations have led to encouraging outcomes in various in vitro and in vivo wound models, and it is expected that some of these technologies will satisfy clinical needs and will enter commercialization.

Abstract
Wound management remains a challenge worldwide, although there are several developed wound dressing materials for the management of acute and chronic wounds. The wound dressings that are currently used include hydrogels, films, wafers, nanofibers, foams, topical formulations, transdermal patches, sponges, and bandages. Hydrogels exhibit unique features which make them suitable wound dressings such as providing a moist environment for wound healing, exhibiting high moisture content, or creating a barrier against bacterial infections, and are suitable for the management of exuding and granulating wounds. Biopolymers have been utilized for their development due to their non-toxic, biodegradable, and biocompatible properties. Hydrogels have been prepared from biopolymers such as cellulose and chitosan by crosslinking with selected synthetic polymers resulting in improved mechanical, biological, and physicochemical properties. They were useful by accelerating wound re-epithelialization and also mimic skin structure, inducing skin regeneration. Loading antibacterial agents into them prevented bacterial invasion of wounds. This review article is focused on hydrogels formulated from two biopolymers-chitosan and cellulose-for improved wound management.

Abstract
BACKGROUND Massive bone defects after wide resection of malignant bone tumors or a serious injury require treatment using vascularized bone grafts. Although cadaveric bone allografts combined with vascularized bone autografts are currently thought to be ideal in terms of size and durability, this treatment requires the scarification of healthy bone tissue. In a previous study, we attempted to improve this situation by prefabricating a vascularized bone allograft in recipient rats. In this study, we added vascular endothelial growth factor (VEGF)-containing hydroxyapatite/collagen composite (HAp/Col) to a prefabricated vascularized bone allograft to stimulate angiogenesis, which is known to be important for bone formation. METHODS Sprague Dawley rats (n = 50) were used as donors and Wistar rats (n = 50) as recipients. All rats were 9 weeks old. The recipient rats were divided into five groups according to the use of vascular bundles, HAp/Col, and an additive substance (VEGF). The bone allografts collected from the donors were transplanted into the thigh region of the recipients, and a saphenous vein and 10 μg HAp/Col with VEGF were inserted into the bone allografts through the slit. After 4 weeks, the transplanted bone allografts were harvested, and histologic and genetic evaluations were performed in relation to bone formation and resorption. RESULTS The results showed that, compared with the control group, the implantation of the vascular bundles and VEGF-containing HAp/Col significantly stimulated angiogenesis and bone formation in the rats with the bone allografts. However, histological and genetic evaluations of bone resorption revealed that resorption was not observed in any group. CONCLUSION These results suggest that VEGF-containing HAp/Col effectively stimulates angiogenesis and bone formation, but not bone resorption, in prefabricated vascularized bone allografts. This method could therefore become a useful tool for treating large bone defects.

Abstract
Vascularization is one of the main challenges in bone tissue engineering (BTE). In this study, vascular endothelial growth factor (VEGF), known for its angiogenic effect, was delivered by our developed sponge, derived from a polyelectrolyte complexes hydrogel between chitosan (CHT) and anionic cyclodextrin polymer (PCD). This sponge, as a scaffold for growth factor delivery, was formed by freeze-drying a homogeneous CHT/PCD hydrogel, and thereafter stabilized by a thermal treatment. Microstructure, water-uptake, biodegradation, mechanical properties, and cytocompatibility of sponges were assessed. VEGF-delivery following incubation in medium was then evaluated by monitoring the VEGF-release profile and its bioactivity. CHT/PCD sponge showed a porous (open porosity of 87.5%) interconnected microstructure with pores of different sizes (an average pore size of 153 μm), a slow biodegradation (12% till 21 days), a high water-uptake capacity (~600% in 2 h), an elastic property under compression (elastic modulus of compression 256 ± 4 kPa), and a good cytocompatibility in contact with osteoblast and endothelial cells. The kinetic release of VEGF was found to exert a pro-proliferation and a pro-migration effect on endothelial cells, which are two important processes during scaffold vascularization. Hence, CHT/PCD sponges were promising vehicles for the delivery of growth factors in BTE.

Abstract
Chronic wounds represent a growing clinical problem for which limited treatment strategies exist. Defects in immune cell-mediated healing play an important role in chronic wound development, presenting an attractive clinical target in the treatment of chronic wounds. However, efforts to improve healing through the application of growth factors and cytokines have been limited by the rapid degradation and diffusion of these molecules in the wound environment. In this study we sought to overcome the challenge of rapid diffusion through the development of a hydrogel delivery system in which protein cargo can be released into the wound environment at a constant and tunable rate. This system was used to deliver the intercellular adhesion molecule-1 (ICAM-1) in order to target endogenous cells upstream of growth factor and cytokine production and circumvent the issue of their rapid degradation. We demonstrated that our delivery system was able to release cargo at different and highly controllable rates and thereby improved cargo retention in the wound environment. Additionally, treatment with ICAM-1 in the delivery system improved healing in both ICAM-1-deficient mice and an aged mouse model of delayed healing, highlighting a potential clinical benefit for this protein in the treatment of chronic wounds.

Abstract
Hyaluronic acid (HA), a non-sulfated glycosaminoglycan (GAG), is a major component of skin extracellular matrix (ECM) and it is involved in the inflammatory response, angiogenesis, and tissue regeneration process. Due to the intrinsic properties of HA (such as biocompatibility, biodegradability and hydrophilic character), it has been used to produce different wound dressings, namely sponges, films, hydrogels, and electrospun membranes. Herein, an overview of the different HA-based wound dressings that have been produced so far is provided as well as the future directions regarding the strategies aimed to improve the mechanical stability of HA-based wound dressings, along with the incorporation of biomolecules intended to ameliorate their biological performance during the healing process.

Abstract
Laser has found increasingly wider applications in the medical filed, but laser is likely to cause damage to patients' skin. In this experiment, we were surprised to find that glyceryl monooleate (GMO)-based cubic liquid crystal had excellent healing effect on the skin of guinea pigs damaged by laser. Transepidermal water loss (TEWL), H.E. pathology, Masson trichrome dyeing, interleukin-6 (IL-6) levels and the percutaneous depth of fluorescein isothiocyanate (FITC) dyeing were used to evaluate the therapeutic effect of GMO-based cubic liquid crystals against laser damage of different degrees among guinea pigs. GMO-based cubic liquid crystals had an obvious effect in the treatment of slight and moderate laser damage. This finding may provide a effective medical treatment protocols for laser skin damage.

Abstract
Globally, chronic wounds impose a notable burden to patients and healthcare systems. Such skin wounds are readily subjected to bacteria that provoke inflammation and hence challenge the healing process. Furthermore, bacteria induce infection impeding re-epithelialization and collagen synthesis. With an estimated global market of $20.4 billion by 2021, appropriate wound dressing materials e.g. those composed of biopolymers originating from nature, are capable of alleviating the infection incidence and of accelerating the healing process. Particularly, biopolymeric nanofibrous dressings are biocompatible and mostly biodegradable and biomimic the extracellular matrix structure. Such nanofibrous dressings provide a high surface area and the ability to deliver antibiotics and antibacterial agents locally into the wound milieu to control infection. In this regard, with the dangerous evolution of antibiotic resistant bacteria, antibiotic delivery systems are being gradually replaced with antibacterial biohybrid nanofibrous wound dressings. This emerging class of wound dressings comprises biopolymeric nanofibers containing antibacterial nanoparticles, nature-derived compounds and biofunctional agents.

Abstract
Epidermal lipoxygenase enzyme extracted from Ambystoma mexicanum (AmbLOXe) is known to accelerate the wound-healing process. AmbLOXe as a protein suffers from inactivation and losing its activity during formulation. Therefore, a delivery system that protects AmbLOXe from inactivation and preserves its activity is needed. We prepared AmbLOXe-loaded pectin nanoparticles (AmbLOXe Pec-NPs) and placed them into an alginate hydrogel. AmbLOXe Pec-NPs incorporation into the alginate hydrogel provides a means for controlled and sustained delivery of AmbLOXe to the wound site. Furthermore, the suitable swelling behavior and mechanical properties of AmbLOXe Pec-NPs alginate hydrogel make it feasible for clinical use. AmbLOXe Pec-NPs alginate hydrogel significantly enhanced the wound-healing process on the rat full-thickness excisional wounds, increased the rate of wound closure, enhanced the re-epithelialization and decreased the incidence of abnormal scarring. AmbLOXe Pec-NPs alginate hydrogel can be proposed as an effective wound hydrogel for improving wound healing with minimal scarring.

Abstract
Aim: Diabetic wound healing is seriously interrupted, and administration of KGF for wound treatment is restricted by its inherent instability. We aim to develop an ideal way toward KGF stabilization, thus improving diabetic wound healing. Materials & methods: We conjugated KGF with gold nanoparticles (GNPs) and determined the stability and binding affinity. Biological effects of conjugates (KGF-GNPs) were evaluated in vitro and in an animal model. Results: KGF-GNPs revealed high stability under hostile circumstances because of the preserved secondary structure and possessed elevated binding affinity to KGF receptor. Moreover, application of KGF-GNPs contributed to accelerated wound recovery in diabetic rats, including re-epithelialization and contraction. Conclusion: KGF-GNPs were promising for future clinical application for diabetic wound therapy.

Abstract
The biomaterials with excellent biocompatibility and biodegradability ¬can lead to satisfactory wound healing. In this study, core-shell structured PU (polyurethane)/St (Starch) and PU/St (Hyaluronic Acid (HA)) nanofibers were fabricated with coaxial electrospinning technique. The morphology characterization of the core-shell structure of nanofibers was investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images. Contact-angle measurements were confirmed the core/shell structure of the electrospun nanofibers with shell and core feed rates of 0.675 L/min and <0.135 L/min, respectively. The average fiber diameter values were calculated for polyurethane nanofibers (836 ± 172.13 nm), PU/St nanofibers (612 ± 93.21 nm) and PU/St (HA) nanofibers (428 ± 78.32 nm). The average porosity values of scaffolds were determined for PU (1.251 ± 0.235 μm), PU/St (1.734 ± 0.284 μm) and PU/St (HA) (3.186 ± 0.401 μm). The core-shell PU/St and PU/St (HA) nanofibers were evaluated in vitro by using mouse fibroblasts (L929) cells. Cell morphology and viability results were exhibited significant enhancement in cell promoting and cell attachment. Furthermore, in vivo studies was indicated Core-shell PU/St (HA) wound dressing can be an appropriate candidate for skin tissue engineering and wound healing.

Abstract
To improve the efficacy of transdermal drug delivery systems, the physical and chemical properties of drugs need to be optimized to better penetrate into the stratum corneum and to better diffuse into the epidermis and dermis layers. Accordingly, dual-biological function ionic liquids composed of active pharmaceutical ingredients were synthesized, comprising both analgesic and anti-inflammatory properties, by combining a cation derived from lidocaine and anions derived from hydrophobic nonsteroidal anti-inflammatory drugs. Active pharmaceutical ingredient ionic liquids (API-ILs) were characterized through nuclear magnetic resonance, cytotoxicity assay, and water solubility assay. All properties were compared with those of the original drugs. By converting the analgesic and anti-inflammatory drugs into dual-function API-ILs, their water solubility increased up to 470-fold, without affecting their cytotoxic profile. These API-ILs were incorporated into a bilayer wound dressing composed of a hydrophobic polyvinylidene fluoride (PVDF) membrane to act as a drug reservoir and a biocompatible hyaluronic acid (HA) layer. The prepared bilayer wound dressing was characterized in terms of mechanical properties, membrane drug uptake and drug release behavior, and application in transdermal delivery, demonstrating to have desirable mechanical properties and improved release of API-ILs. The assessment of anti-inflammatory activity through the inhibition of LPS-induced production of nitric oxide and prostaglandin E2 by macrophages revealed that the prepared membranes containing API-ILs are as effective as those with the original drugs. Cell adhesion of fibroblasts on membrane surfaces and cell viability assay confirmed improved the viability and adhesion of fibroblasts on PVDF/HA membranes. Finally, wound healing assay performed with fibroblasts showed that the bilayer membranes containing dual-function API-ILs are not detrimental to wound healing, while displaying increased and controlled drug delivery and dual therapeutic behavior. STATEMENT OF SIGNIFICANCE: This work shows the preparation and characterization of bilayer wound dressings comprising dual-biological function active pharmaceutical ingredients based on ionic liquids with improved and controlled drug release and dual therapeutic efficiency. By converting analgesic and anti-inflammatory drugs into ionic liquids, their water solubility increases up to 470-fold. The prepared bilayer wound dressing membranes have desirable mechanical properties and improved release of drugs. The prepared membranes comprising ionic liquids display anti-inflammatory activity as effective as those with the original drugs. Cell adhesion of fibroblasts on membrane surfaces and cell viability assays show improved viability and adhesion of fibroblasts on PVDF/HA membranes, being thus of high relevance as effective transdermal drug delivery systems.

Abstract
In the repair of large segmental bone defects, bone tissue is often unable to heal due to the destruction of the vascular network near the wound site. An ideal bone repair material should have both angiogenic and osteogenic capabilities. To achieve this goal, we used biodegradable mesoporous silica nanoparticles (MSNs) as a delivery vehicle for dexamethasone (DEX), a small-molecule drug that induces osteogenic differentiation. Subsequently, chitosan was covalently modified onto the surface of the nanoparticles by glycidoxypropyltrimethoxysilane (GPTMS) to construct nanoparticulate delivery systems (DEX@chi-MSNs) that induce osteoblast formation. The QK peptide, which mimics the α-helical structure of vascular endothelial growth factor (VEGF) binding to the receptor, was adsorbed to the surface of chitosan-modified MSNs nanoparticles (QK@chi-MSNs) to render them with angiogenic ability. The QK@chi-MSNs can promote the formation of the tubular structure of human umbilical vein endothelial cells (HUVECs) and angiogenesis in vivo, as demonstrated by a chicken embryo chorioallantoic test (CAM) and subcutaneous embedding test. The DEX@chi-MSNs can improve alkaline phosphatase (ALP) activity, mineralized nodule formation, and the expression of osteogenic-related genes and proteins by BMSCs. Furthermore, the ability of bone repair and angiogenesis was evaluated in a critical size skull defect model in rats by using nanocarriers loaded with both DEX and QK (QK/DEX@chi-MSNs). The results of computed tomography (CT) scan, histological examination, and immunofluorescence staining indicated that QK/DEX@chi-MSNs can promote bone formation and angiogenesis in vivo, which has broad application prospects in bone tissue engineering.

Abstract
The delivery of growth factors is often challenging due to their short half-life, low stability, and rapid deactivation. In native tissues, the sulfated residual of glycosaminoglycan (GAG) polymer chains of proteoglycans immobilizes growth factors through the proteoglycans'/proteins' complexation with nanoscale organization. These biological assemblies can influence growth factor-cell surface receptor interactions, cell differentiation, cell-cell signaling, and mechanical properties of the tissues. Here, we introduce a facile procedure to prepare novel biomimetic proteoglycan nanocarriers, based on naturally derived polymers, for the immobilization and controlled release of growth factors. We developed polyelectrolyte complex nanoparticles (PCNs) as growth factor nanocarriers, which mimic the dimensions, chemical composition, and growth factor immobilization of proteoglycans in native tissues. PCNs were prepared by a polymer-polymer pair reaction method and characterized for physicochemical properties. Fourier transform infrared spectroscopy (FTIR) analysis indicated that complexation occurred through electrostatic interactions. Transmission electron microscopy (TEM) results showed that the nanocarriers had a diameter of 60 ± 11 nm and 91 ± 33 nm for dermatan sulfate sodium salt-poly-l-lysine (DS-PLL) and gum tragacanth-poly-l-lysine (GT-PLL) complexes, respectively. The colloidal nanoparticles were stable due to their negative zeta potential, i.e.-25 ± 4 mV for DS-PLL and -18 ± 3.5 mV for GT-PLL. Cytocompatibility of PCNs in contact with human bone marrow stromal cells (HS-5) was confirmed through a live/dead assay and metabolic activity measurement. In addition, vascular endothelial growth factor (VEGF) was used to evaluate the ability of PCNs to stabilize growth factors. The capability of PCNs to preserve VEGF activity for up to 21 days was confirmed by analyzing the metabolic and mitogenic characteristics of human umbilical vein endothelial cells (HUVECs). Our results demonstrated the potential applications of these nanoparticles in therapeutic delivery for tissue regeneration applications.

Abstract
In general, the systems intended for the treatment and recovery of wounds, seek to act as a coating for the damaged area, maintaining an adequate level of humidity, reducing pain, and preventing the invasion and proliferation of microorganisms. Although many of the systems that are currently on the market meet the purposes mentioned above, with the arrival of nanotechnology, it has sought to improve the performance of these coatings. The variety of nano-systems that have been proposed is very extensive, including the use of very different materials (natural or synthetic) ranging from polymers or lipids to systems derived from microorganisms. With the objective of improving the performance of the systems, seeking to combat several of the problems that arise in a wound, especially when it is chronic, these materials have been combined, giving rise to nanocomposites or scaffolds. In recent years, the interest in the development of systems for the treatment of wounds is notable, which is reflected in the increase in publications related to the subject. Therefore, this document presents generalities of systems involving nanocarriers, mentioning some examples of representative systems of each case.

Abstract
Chronic skin wounds are the leading cause of nontraumatic foot amputations worldwide and present a significant risk of morbidity and mortality due to the lack of efficient therapies. The intrinsic characteristics of hydrogels allow them to benefit cutaneous healing essentially by supporting a moist environment. This property has long been explored in wound management to aid in autolytic debridement. However, chronic wounds require additional therapeutic features that can be provided by a combination of hydrogels with biochemical mediators or cells, promoting faster and better healing. We survey hydrogel-based approaches with potential to improve the healing of chronic wounds by reviewing their effects as observed in preclinical models. Topics covered include strategies to ablate infection and resolve inflammation, the delivery of bioactive agents to accelerate healing, and tissue engineering approaches for skin regeneration. The article concludes by considering the relevance of treating chronic skin wounds using hydrogel-based strategies.

Abstract
Advances in nanoparticle (NP) production and demand for control over nanoscale systems have had significant impact on tissue engineering and regenerative medicine (TERM). NPs with low toxicity, contrasting agent properties, tailorable characteristics, targeted/stimuli-response delivery potential, and precise control over behavior (via external stimuli such as magnetic fields) have made it possible their use for improving engineered tissues and overcoming obstacles in TERM. Functional tissue and organ replacements require a high degree of spatial and temporal control over the biological events and also their real-time monitoring. Presentation and local delivery of bioactive (growth factors, chemokines, inhibitors, cytokines, genes etc.) and contrast agents in a controlled manner are important implements to exert control over and monitor the engineered tissues. This need resulted in utilization of NP based systems in tissue engineering scaffolds for delivery of multiple growth factors, for providing contrast for imaging and also for controlling properties of the scaffolds. Depending on the application, materials, as polymers, metals, ceramics and their different composites can be utilized for production of NPs. In this review, we will cover the use of NP systems in TERM and also provide an outlook for future potential use of such systems.

Abstract
In recent years, applications of biopolymers such as hyaluronic acid (HA) for wound dressing have attracted more attention. However, the poor mechanical properties of HA-based wound dressings limit their clinical applications. Incorporation of reinforcing agents such as nanocrystalline cellulose (CNC) in HA-based wound dressings can improve their mechanical properties. In addition, controlled delivery of growth factors to the wound site using nanoparticles can significantly improve the healing process. In this study, we focus on development and characterization of a novel CNC reinforced HA-based composite containing chitosan nanoparticles loaded with GM-CSF (CNC-HA/GM-CSF-Chi-NPs composite) as an effective wound dressing. CNC-HA/GM-CSF-Chi-NPs composite showed some physicochemical characteristics such as appropriate mechanical properties, high swelling capacity (swelling ratio: 2622.1% ± 35.2%) and controlled release of GM-CSF up to 48 h which make it an excellent candidate for wound dressing. In vivo investigation showed that, after 13 d, the wounds covered with CNC-HA/GM-CSF-Chi-NPs composite could reach to nearly full wound closure and complete re-epithelialization compared to the normal saline treated wounds which exhibited nearly 70% of wound size reduction. Furthermore, the CNC-HA/GM-CSF-Chi-NPs composite treated wounds exhibited significantly lower inflammatory reaction, enhanced re-epithelialization and improved granulation tissue formation compared with CNC-HA/Chi-NPs composite treated wound; it might be due to positive effects of GM-CSF on the wound healing process. Our results suggest that CNC-HA/GM-CSF-Chi-NPs composite can be potentially applied in clinical practice for wound treatment.

Abstract
Wound management in diabetic patient is of an extreme clinical and social concern. The delayed and impaired healing makes it more critical for research focus. The research on impaired healing process is proceeding hastily evident by new therapeutic approaches other than conventional such as single growth factor, dual growth factor, skin substitutes, cytokine stimulators, cytokine inhibitors, matrix metalloproteinase inhibitors, gene and stem cell therapy, extracellular matrix and angiogenesis stimulators. Although numerous studies are available that support delayed wound healing in diabetes but detailed mechanistic insight including factors involved and their role still needs to be revealed. This review mainly focuses on the molecular cascades of cytokines (with growth factors) and erstwhile factors responsible for delayed wound healing, molecular targets and recent advancements in complete healing and its cure. Present article briefed recent pioneering information on possible molecular targets and treatment strategies including clinical trials to clinicians and researchers working in similar area.

Abstract
High mortality rate in potentially survivable casualties due to severe hemorrhage is a major challenge in today's battlefield because technological advancements have revolutionized the combat tactics and complicated the type and severity associated with wound grades. Quality of pre-hospital care prior to patient evacuation is crucial in determining the survival rate in injured patients. To deal with this challenge, considerable improvements in the hemostatic dressings have been introduced and pre-hospital care has been upgraded in many tactical combat casually care guidelines. Combat Gauze has been widely used bandage which is now been replaced by different chitosan based hemostatic dressings. It not only exhibits anti-bacterial activity but also induces hemostasis via direct interaction with erythrocytes and platelets. Its hemostasis mechanism is not dependent on host coagulation pathway which makes it an ideal dressing to stop bleeding in coagulopathic patients. Different generations of chitosan bandages have been developed to overcome the limitations of previous ones. This review provides performance analysis of chitosan bandage generations and discusses the progress made in its fabrication methods during the recent years.

Abstract
Due to the syringeability of precursor solution and convenience of open surgical treatment, injectable hydrogels have gained growing attention in drug delivery application. For load-bearing tissue, the excellent mechanical property is an important requirement for delivery vehicles to resist external stress and loads. Herein, we prepared mechanically robust injectable hydrogels (HA/γ-PGA hydrogels for short) using methacrylate-functionalized hyaluronic acid and poly (γ-glutamic acid) via photopolymerization. The HA/γ-PGA hydrogels showed outstanding anti-compression ability and could suffer a more than 80% strain. Meanwhile, after 5 cycles of compression, HA/γ-PGA hydrogels could still recover quickly against external stress, showing excellent shape recovery capability. Moreover, the mechanical properties could be modulated easily by changing the molar ratio of HA to γ-PGA. The drug release behavior was also evaluated and the drug-loaded HA/γ-PGA hydrogels showed a weak burst release and sustained release behavior. Additionally, HA/γ-PGA hydrogels also exhibited superior biocompatibility. Therefore, HA/γ-PGA hydrogels have great potential as injectable drug carriers for load-bearing tissue application.

Abstract
Dressings are commonly used to treat skin wounds. In this study, we aimed to develop a new scaffold composed of a polyvinyl alcohol (PVA) hydrogel containing granule-lyophilised platelet-rich fibrin (G-L-PRF) as a dressing. G-L-PRF was prepared by freeze-drying and was then incorporated into PVA hydrogel by freezing-thawing. Notably, the mechanical strength and degradation rate of the scaffold were found to be related to G-L-PRF concentrations, reaching 6.451 × 10−2 MPa and 17–22%, respectively, at a concentration of 1%. However, the strength decreased and the degradation was accelerated when the G-L-PRF concentration was over 1%. The elastic properties and biocompatibility of the scaffold were independent of G-L-PRF concentration, and both showed excellent elasticity and biocompatibility. The release of vascular endothelial growth factor and platelet-derived growth factor-AB was no significant time dependent. Additionally, application of 1% G-L-PRF/PVA to acute full-thickness dorsal skin wounds accelerated wound closure at days 7 and 9. Healing also increased on day 11. Histological and immunohistochemical analyses showed that the scaffold enhanced granulation tissue, maturity, collagen deposition, and new vessel formation. These results demonstrated that the prepared G-L-PRF/PVA scaffolds accelerated wound healing in acute full-thickness skin wounds, suggesting potential applications as an ideal wound dressing.

Abstract
New membranes based on chitosan and chitosan-hyaluronic acid containing new arginine derivatives with thiazolidine-4-one scaffold have been prepared using the ionic cross-linking method. The presence of the arginine derivatives with thiazolidine-4-one scaffold into the polymer matrix was proved by Fourier-transform infrared spectroscopy (FT-IR). The scanning electron microscopy (SEM) revealed a micro-porous structure that is an important characteristic for the treatment of burns, favoring the exudate absorption, the rate of colonization, the cell structure, and the angiogenesis process. The developed polymeric membranes also showed good swelling degree, improved hydrophilicity, and biocompatibility in terms of surface free energy components, which supports their application for tissue regeneration. Moreover, the chitosan-arginine derivatives (CS-6h, CS-6i) and chitosan-hyaluronic acid-arginine derivative (CS-HA-6h) membranes showed good healing effects on the burn wound model induced to rats. For these membranes a complete reepithelialization was observed after 15 days of the experiment, which supports a faster healing process.

Abstract
Chitosan composite material has been used as an efficient drug carrier for potential drug delivery systems in specific cases of wound dressing management. In the present study, 0.5 g/L of the antibiotic tetracycline hydrochloride (TCH) was loaded into 1% fungal chitosan (FCS) incorporated with 0.2% of Aloe vera extract (AVE). Two types of sponges were prepared, with and without AVE, such as FCS-AVE-TCH and FCS-TCH, respectively. They were characterized by UV–Visible spectrophotometer, attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), and scanning electron microscopy (SEM). A constant amount of cumulative TCH release was observed from FCS-AVE-TCH composite sponges at the phosphate buffer saline (pH 7.4), they exhibited good antibacterial activity against both Gram-positive and Gram-negative bacteria. Furthermore, the Vero cells (African green monkey kidney cell line) treated by the composites showed augmented cell viability, which suggests that it could be used as a cost-effective, potential wound dressing material.

Abstract
Polysaccharides or polymeric carbohydrate molecules are long chains of monosaccharides that are linked by glycosidic bonds. The naturally based structural materials are widely applied in biomedical applications. This article covers four different types of polysaccharides (i.e., alginate, chitosan, hyaluronic acid, and dextran) and emphasizes their chemical modification, preparation approaches, preclinical studies, and clinical translations. Different cargo fabrication techniques are also presented in the third section. Recent progresses in preclinical applications are then discussed, including tissue engineering and treatment of diseases in both therapeutic and monitoring aspects. Finally, clinical translational studies with ongoing clinical trials are summarized and reviewed. The promise of new development in nanotechnology and polysaccharide chemistry helps clinical translation of polysaccharide-based drug delivery systems.

Abstract
Skin wound healing aims to repair and restore tissue through a multistage process that involves different cells and signalling molecules that regulate the cellular response and the dynamic remodelling of the extracellular matrix. Nowadays, several therapies that combine biomolecule signals (growth factors and cytokines) and cells are being proposed. However, a lack of reliable evidence of their efficacy, together with associated issues such as high costs, a lack of standardization, no scalable processes, and storage and regulatory issues, are hampering their application. In situ tissue regeneration appears to be a feasible strategy that uses the body's own capacity for regeneration by mobilizing host endogenous stem cells or tissue-specific progenitor cells to the wound site to promote repair and regeneration. The aim is to engineer instructive systems to regulate the spatio-temporal delivery of proper signalling based on the biological mechanisms of the different events that occur in the host microenvironment. This review describes the current state of the different signal cues used in wound healing and skin regeneration, and their combination with biomaterial supports to create instructive microenvironments for wound healing.

Abstract
Produced through electrospinning, poly(l-lactide-co-caprolactone) (PLCL) membranes, which have a porous structure and are biodegradable, are of interest in various medical fields. The porous-structured electrospun membrane is particularly interesting because of several favorable properties as follows: it exudes fluid from the wound, does not build up under the wound covering, and does not cause wound desiccation. Moreover, extracellular matrix (ECM)-based structures derived by tissue decellularization have application as engineered tissue scaffolds and as supports for cellular regeneration. In particular, heart decellularized ECM (hdECM) has various pro-angiogenic factors that can induce angiogenesis for wound healing. In this regard, a nanofibrous electrospun hdECM-based hybrid scaffold (NEhdHS), which is a PLCL membrane, including hdECM as an active agent, was tested as a wound dressing to assess its fundamental biochemical and physical features in wound healing. Use of NEhdHS with its porous structure and pro-angiogenic factors is expected to provide an effective wound dressing and reduced scarring. We first demonstrate the effectiveness of a proposed decellularization protocol through analysis of dECM components and describe the mechanical properties of the fabricated NEhdHS. Next, we present an in vitro angiogenesis analysis of the NEhdHS, using a coculture system with human dermal fibroblasts and human umbilical vein endothelial cells; the results of which confirm its biocompatibility and show that the NEhdHS can significantly enhance angiogenesis over that obtained from PLCL or gelatin-containing PLCL scaffolds. We also studied the effectiveness of the NEhdHS in vivo. Using a rat excisional wound-splinting model, we show that covering the upper part of the wound with NEhdHS significantly reduces scarring in the wound healing process compared to that with PLCL or gelatin-containing PLCL scaffolds. Based upon its properties, we conclude that the NEhdHS has potential for application in wound dressing.

Abstract
Abdominal wall defect caused by open abdomen (OA) or abdominal trauma is a serious issue since it induces several clinical problems. Although a variety of prosthetic materials are commonly employed, complications occur including host soft tissue response, fistula formation and chronic patient discomfort. Recently, abundant natural polymers have been used for injectable hydrogel synthesis in tissue regeneration. In this study, we produced the chitosan - hyaluronic acid (CS/HA) hydrogel and investigated its effects on abdominal tissue regeneration. The physical and biological properties of the hydrogel were demonstrated to be suitable for application in abdominal wounds. In a rat model simulating open abdomen and large abdominal wall defect, rapid cellular response, sufficient ECM deposition and marked neovascularization were found after the application of the hydrogel, compared to the control group and fibrin gel group. Further, the possible mechanism of these findings was studied. Cytokines involved in angiogenesis and cellular response were increased and the skew toward M2 macrophages credited with the functions of anti-inflammation and tissue repair was showed in CS/HA hydrogel group. These findings suggested that CS/HA hydrogel could prevent the complications and was promising for abdominal tissue regeneration.

Abstract
The porous structured and cell proliferative biodegradable fungal chitosan (FCS) based composites with potential antibacterial property was prepared with Aloe vera extract (ALE) and the plant Cuscuta reflexa mediated biosynthesized silver nanoparticles (CUS-AgNPS) were developed for wound dressing applications by freeze drying method. Fungal chitosan was derived from Cunninghamella elegans a species belongs the family of Zygomycetes. The CUS-AgNPS were characterized by the UV-vis spectrum, XRD and SEM. CUS-AgNPS were loaded into the FCS-ALE sponges and were characterized by UV-vis spectrum, FT-IR and SEM. The nanocomposite sponges (FCS-ALE/CUS-AgNPS) showed prominent results against the different pathogenic bacteria and did not affect the cells were tested in vitro cell viability against human dermal fibroblast cell (HDF cells) which revealed significant cell viability. Based on these observations our composite formulation (FCS/ALE/CUS-AgNPS) could be suggested potential for wound dressing applications.

Spongy bilayer dressing composed of chitosan-Ag nanoparticles and chitosan-Bletilla striata polysaccharide for wound healing applications. Carbohydr Polym 2016; 157:1538-1547.

Abstract
The purpose of this study was to develop a promising wound dressing. Though chitosan cross-linked with genipin has been widely used as biomaterials, with the addition of partially oxidized Bletilla striata polysaccharide, the newly developed material in this study (coded as CSGB) showed less gelling time, more uniform aperture distribution, higher water retention, demanded mechanical strength and more L929 cell proliferation compared to the chitosan cross-linked only with genipin. Owning to partial blocking of free amino groups of chitosan, CSGB revealed almost no antibacterial activities, thus the bilayer composite of chitosan-silver nanoparticles (CS-AgG) on CSGB was designed to inhibit microbial invasion. The in vivo studies indicated that both CSGB and bilayer wound dressing significantly accelerated the healing rate of cutaneous wounds in mice, and the bilayer exhibited better mature epidermization with less inflammatory cells on Day 7. Therefore, this novel bilayer composite has great potential in wound dressing applications.
