Adipose-Derived Stromal Cells within a Gelatin Matrix Acquire Enhanced Regenerative and Angiogenic Properties: A Pre-Clinical Study for Application to Chronic Wounds. Biomedicines 2023; 11:biomedicines11030987. [PMID: 36979966 PMCID: PMC10046849 DOI: 10.3390/biomedicines11030987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 03/13/2023] [Accepted: 03/15/2023] [Indexed: 03/30/2023] Open
Abstract
This study evaluates the influence of a gelatin sponge on adipose-derived stromal cells (ASC). Transcriptomic data revealed that, compared to ASC in a monolayer, a cross-linked porcine gelatin sponge strongly influences the transcriptome of ASC. Wound healing genes were massively regulated, notably with the inflammatory and angiogenic factors. Proteomics on conditioned media showed that gelatin also acted as a concentrator and reservoir of the regenerative ASC secretome. This secretome promoted fibroblast survival and epithelialization, and significantly increased the migration and tubular assembly of endothelial cells within fibronectin. ASC in gelatin on a chick chorioallantoic membrane were more connected to vessels than an empty sponge, confirming an increased angiogenesis in vivo. No tumor formation was observed in immunodeficient nude mice to which an ASC gelatin sponge was transplanted subcutaneously. Finally, ASC in a gelatin sponge prepared from outbred rats accelerated closure and re-vascularization of ischemic wounds in the footpads of rats. In conclusion, we provide here preclinical evidence that a cross-linked porcine gelatin sponge is an optimal carrier to concentrate and increase the regenerative activity of ASC, notably angiogenic. This formulation of ASC represents an optimal, convenient and clinically compliant option for the delivery of ASC on ischemic wounds.

Abstract
The conversion of liquid resin into solid structures upon exposure to light of a specific wavelength is known as photopolymerization. In recent years, photopolymerization-based 3D printing has gained enormous attention for constructing complex tissue-specific constructs. Due to the economic and environmental benefits of the biopolymers employed, photo-curable 3D printing is considered an alternative method for replacing damaged tissues. However, the lack of suitable bio-based photopolymers, their characterization, effective crosslinking strategies, and optimal printing conditions are hindering the extensive application of 3D printed materials in the global market. This review highlights the present status of various photopolymers, their synthesis, and their optimization parameters for biomedical applications. Moreover, a glimpse of various photopolymerization techniques currently employed for 3D printing is also discussed. Furthermore, various naturally derived nanomaterials reinforced polymerization and their influence on printability and shape fidelity are also reviewed. Finally, the ultimate use of those photopolymerized hydrogel scaffolds in tissue engineering is also discussed. Taken together, it is believed that photopolymerized 3D printing has a great future, whereas conventional 3D printing requires considerable sophistication, and this review can provide readers with a comprehensive approach to developing light-mediated 3D printing for tissue-engineering applications.

Pullulan-Collagen Hydrogel Wound Dressing Promotes Dermal Remodeling and Wound Healing Compared to Commercially Available Collagen Dressings. Wound Repair Regen 2022; 30:397-408. [PMID: 35384131 PMCID: PMC9321852 DOI: 10.1111/wrr.13012] [Citation(s) in RCA: 23] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 03/09/2022] [Accepted: 03/31/2022] [Indexed: 12/03/2022]
Abstract
Biological scaffolds such as hydrogels provide an ideal, physio‐mimetic of native extracellular matrix (ECM) that can improve wound healing outcomes after cutaneous injury. While most studies have focused on the benefits of hydrogels in accelerating wound healing, there are minimal data directly comparing different hydrogel material compositions. In this study, we utilized a splinted excisional wound model that recapitulates human‐like wound healing in mice and treated wounds with three different collagen hydrogel dressings. We assessed the feasibility of applying each dressing and performed histologic and histopathologic analysis on the explanted scar tissues to assess variations in collagen architecture and alignment, as well as the tissue response. Our data indicate that the material properties of hydrogel dressings can significantly influence healing time, cellular response, and resulting architecture of healed scars. Specifically, our pullulan‐collagen hydrogel dressing accelerated wound closure and promoted healed tissue with less dense, more randomly aligned, and shorter collagen fibres. Further understanding of how hydrogel properties affect the healing and resulting scar architecture of wounds may lead to novel insights and further optimization of the material properties of wound dressings.

Abstract
A variety of wound matrix materials that are designed to help heal both acute and chronic wounds are currently available. Because wounds often encounter opportunistic microbes that can delay healing, the effectiveness of these materials is often suboptimal, resulting in delayed or compromised wound healing. The importance of reducing and controlling wound microbes is well recognised and there are several antimicrobial options available to address this unmet clinical need. This study compares the antimicrobial and wound healing capabilities, both in vivo and in vitro against methicillin-resistant Staphylococcus aureus (MRSA) USA 300, for the following compounds: Collagen Wound Matrix-Anti Microbial (CWM-AM); Collagen Wound Matrix-Anti Microbial XT (CWM-AM XT); Antimicrobial Hydrofiber Wound Dressing (AHWD); Dermal Scaffold with Silver (DRSAg); Collagen Extracellular Matrix (CEM); Collagen Wound Matrix (CWM); Matrix Wound Dressing with Silver (MWDAg); Cadexomer Iodine Gel (CIG); Triple Antibiotic Ointment (TAO); and Antimicrobial Wound Gel (AWG). For the in vitro zone of inhibition assay, AWG and CIG had the largest diffused areas, followed by CWM-AM and CWM-AM XT. Furthermore, CWM-AM, CWM-AM XT, AWG, and CIG exhibited a persistent antimicrobial activity for up to 10 days after incubation. However, in the cytotoxicity studies performed using human fibroblasts, CWM-AM and CWM-AM XT had no detrimental effects in cell proliferation and viability, while AWG and CIG were cytotoxic and prohibitive for cell proliferation. Treatments were then assessed for microbiology and wound healing efficacy using an in vivo porcine deep reticular dermal wound model. CWM-AM XT displayed the greatest in vivo antimicrobial activity against MRSA USA300 and expedited the reepithelialisation at a faster rate than other treatment groups. This study shows that a novel collagen matrix containing an antimicrobial agent can reduce the bacterial load and support healing.

Safety and Efficacy of Collagen-Based Biological Dressings in the Management of Chronic Superficial Skin Wounds in Non-Complex Trauma: A Post-Marketing Surveillance Study. TRAUMA CARE 2021.

Abstract
Biological dressings such as collagen and hyaluronic acid represent the main advanced tools that plastic surgeons, dermatologists and vulnologists use today to treat chronic wounds or ulcers that do not tend to heal. These types of dressings are important because they create a moist and physiological interface at the wound level, are of natural origin, easy to use, hypo-allergenic, economical and do not create discomfort for the patient during dressing changes. We treated 128 patients (divided into four groups based on type of dressing) with non-complex superficial chronic wounds in comparison with a traditional dressing (fitostimoline gauze or polyurethane foam). We analyzed wound characteristics, healing time, and operator and patient satisfaction. A significantly higher recovery rate was observed in the “Collagen-coated plates” treatment group compared to Standard Treatment. Additionally, a significantly higher probability of recovery was observed compared to the alternative two experimental devices (Collagen-coated plates + HA and Collagen-based spray). However, the main limitation of the randomization of this study is the presence in the “Collagen-based spray” group of localized wounds, mainly in the fingers and hand. No side effects were reported in relation to the procedures or the experimental products. Collagen may be considered as a valuable therapeutic tool in non-complex chronic wounds by virtue of its low immunogenicity, flexibility and applicability in biocompatible scaffolds, and represents driving force toward enhanced wound care.

Abstract
Collagen (Col) and gelatin are most extensively used in various fields, particularly in pharmaceuticals and therapeutics. Numerous researchers have proven that they are highly biocompatible to human tissues, exhibit low antigenicity and are easy to degrade. Despite their different sources both Col and gelatin have almost the same effects when it comes to wound healing mechanisms. Considering this, the bioactivity and biological effects of both Col and gelatin have been, and are being, constantly investigated through in vitro and in vivo assays to obtain maximum outcomes in the future. With regard to their proven nutritional values as sources of protein, Col and gelatin products exert various possible biological activities on cells in the extracellular matrix (ECM). In addition, a vast number of novel Col and gelatin applications have been discovered. This review compared Col and gelatin in terms of their structures, sources of derivatives, physicochemical properties, results of in vitro and in vivo studies, their roles in wound healing and the current challenges in wound healing. Thus, this review provides the current insights and the latest discoveries on both Col and gelatin in their wound healing mechanisms.

Abstract
Infection is one of several factors that can delay normal wound healing. Antibacterial wound dressings can therefore promote normal wound healing. In this study, we prepared an antibacterial wound dressing, consisting of visible light-cured methacrylated collagen (ColMA) hydrogel and a 2-hydroxypropyl-beta-cyclodextrin (HP-β-CD)/triclosan (TCS) complex (CD-ic-TCS), and evaluated its wound healing effects in vivo. The 1H NMR spectra of ColMA and CD-ic-TCS revealed characteristic peaks at 1.73, 5.55, 5.94, 6.43, 6.64, 6.84, 6.95, 7.31, and 7.55 ppm, indicating successful preparation of the two material types. In addition, ultraviolet-visible (UV-vis) spectroscopy proved an inclusion complex formation between HP-β-CD and TCS, judging by a unique peak observed at 280 cm-1. Furthermore, ColMA/CD-ic-TCS exhibited an interconnected porous structure, controlled release of TCS, good biocompatibility, and antibacterial activity. By in vivo animal testing, we found that ColMA/CD-ic-TCS had a superior wound healing capacity, compared to the other hydrocolloids evaluated, due to synergistic interaction between ColMA and CD-ic-TCS. Together, our findings indicate that ColMA/CD-ic-TCS has a clinical potential as an antibacterial wound dressing.

Abstract
BACKGROUND Our objective was to explore a synthetic alginate hydrogel delivery system for the delivery of demineralized bone matrix (DBM) particles for bone graft substitutes. MATERIAL AND METHODS The physiochemical properties of surface morphology, porosity measurements, in vitro degradation, equilibrium swelling, and mechanical testing of combined DBM powder and alginate in amounts of 0 mg/1 mL, 25 mg/1 mL, 50 mg/1 mL, and 100 mg/1 mL were detected. In vitro cell culture and in vivo studies using Sprague-Dawley rats were performed to evaluate the biocompatibility and osteoinductivity of DBM-alginate (ADBM) composites. RESULTS DBM particles were uniformly scattered in all composites, and macro-scale pores were omnipresent. All composites showed a similar low degradation rate, with approximately 85% of weight remaining after 15 days. As the concentration of DBM particles in composites increased, degradation in collagenase and elastic modulus increased and the pore area and swelling ratio significantly decreased. No cytotoxicity of ADBM or alginate on mesenchymal stem cells (MSCs) was observed. Cell cultivation with ADBM showed greater osteogenic potential, evidenced by the upregulation of alkaline phosphatase and alizarin red staining activity and the mRNA expression level of marker genes RUNX2, OCN, OPN, and collagen I compared with the cells grown in alginate. Evaluation of ectopic bone formation revealed the osteoinductivity of the ADBM composites was significantly greater than that of DBM particles. Osteoinduction of the composites was demonstrated by a cranial defect model study. CONCLUSIONS The delivery of DBM particles using a synthetic alginate hydrogel carrier may be a promising approach in bone tissue engineering for bone defects.

Abstract
Active collagen type I successfully used in regenerative medicine. However, despite the large amount of material of cellular and molecular mechanisms underlying skin repair, the molecular mechanisms of wound healing with use collagen type I, not studied enough. PURPOSE OF THE STUDY To study the mechanism of the native collagen type I wound-healing action of native type I collagen on the example of the medical device Collost (7% gel) in a model of the rats difficult-to-heal skin wounds. MATERIAL AND METHODS Male rats in population SD (72 individuals) surgically formed an ischemic dorsal skin flap (3×10 cm) with two full-thickness skin wounds 6 mm in diameter.The trained animals divided into 2 groups: in the experimental group, medical device Collost (gel) applied once after the operation, in the control group - a standard medical device for comparison. The dynamics of wound healing assessed, the number of M2 macrophages, myofibroblasts, vascularization and expression of the main markers of the repair process in the wound tissues and time points for assessment were: after 3, 7 and 14 days after operation using macroscopic, immunohistochemical, and molecular methods. RESULTS It has been established that the mechanism of action of native collagen type I is associated with the acceleration of the appearance of «progenitorous» M2-macrophages in the wound tissues, decrease in the severity of inflammation or reduction in the duration of the inflammatory stage of the repair process, change in the expression spectrum of number of growth factors, an acceleration of neovasculogenesis. CONCLUSION In this work, on the modern experimental model shown regenerative efficiency of a medical device based on collagen type I and described the molecular and cellular processes of wound healing when using it It has been shown that the acceleration of wound healing processes occurs when using a medical device based on native collagen type 1, it is also accompanied by a better aesthetic closure of the damaged skin area.

Abstract
Abstract
The treatment of chronic wounds is a continuously developing research focus. The problems of excessive mechanical forces, infection, inflammation, reduced production of growth factors, and lack of collagen will affect the results of treatment. The purpose of this study was to analysse the elements that lead to long-term non-healing of chronic wounds and trophic ulcers, including diabetic foot syndrome, by determining the optimal treatment algorithm. The paper presents an analysis of the world literature on the etiopathogenesis and principles of chronic wound treatment in diabetic foot syndrome. The epidemiology of chronic wounds of different genesis is presented. The issues of physiological and metabolic disorders in chronic ulcers affecting the process of wound healing are discussed. Particular attention is paid to collagen, which is a protein that forms the basis of connective tissue; collagen ensures the strength and elasticity of the skin, which confirms the importance of its role not only in aesthetics but also in the process of wound healing. Different types of collagen and their roles in the mechanisms of chronic wound healing in diabetic foot syndrome are described. The results of clinical studies evaluating the effectiveness of medical products and preparations, consisting of collagen with preserved (native collagen) and fractionated structures, in treating chronic wounds of diabetic foot syndrome are analysed. It has been shown that the use of native collagen preparations is a promising treatment for chronic ulcers and wounds, including diabetic foot syndrome, which makes it possible to increase the effectiveness of treatment and reduce the economic costs of managing these patients.

Abstract
The pharmacological modulation of collagen turnover is a strategy potentially useful in different skin conditions. The serine protease inhibitor Serpin A1 and portions of its C-terminal region have been investigated as collagen modulators. To clarify the mechanisms by which the C-terminal 409-418 peptide SA1-III increases extracellular type I collagen levels, to compare its activities range with that of the originator molecule Serpin A1, and to evaluate its efficacy in primary cultures from adult and aged human subjects. The different forms of type I collagen were analyzed by means of western blot in cell lysates and cell-conditioned media of primary human dermal fibroblasts obtained from subjects of different ages. Gelatin zymography was used to investigate the degrading enzymes. Cell viability and in vitro wound healing tests were used to evaluate cell proliferation. The SA1-III peptide increased extracellular collagen levels by reducing degradation, with no effect on cellular biosynthesis or cell proliferation mechanisms. A reduced level of MMP-2 and MMP-9 was also found in cell media upon peptide treatment. No peptide effect was detected on inflammatory mediators gene expression in resting and LPS-stimulated fibroblasts, or in the wound healing test. The SA1-III peptide is a good collagen modulator candidate, protecting collagen against degradation without detectable actions on biosynthesis, acting at reasonably low concentrations, and non-interfering with cell proliferation. It is effective in primary fibroblasts from young and aged subjects. These effects can prove useful in pathological and physiological skin conditions in which collagen degradation is excessive compared to the synthetic capacity.

Abstract
Microbial infection has been considered as one of the most critical challenges in bioengineering applications especially in tissue regeneration, which engenders severe threat to public health. Herein, a hydrogel performing properties of rapid self-healing, on-demand antibiosis and controlled cargo release was fabricated by a simple assembly of Fe complex as the cross-linker and hyaluronic acid as the gel network. This hydrogel is able to locally degrade and release Fe3+ to kill bacteria as needed because of hyaluronidase excreted by surrounding bacteria, resulting in efficient antibacterial activity against different types of bacteria. The sustained release property of certain types of growth factors was also observed from this hydrogel owing to its dense network. Moreover, this hydrogel could repeatedly heal itself in minutes because of the coordination interaction between Fe3+ and COOH, exhibiting good potential in bioengineering applications on the exposed tissue, where the materials are easily damaged during daily life. When topically applied onto damaged mouse skin with infection of Staphylococcus aureus, the hydrogel is able to inhibit microbial infections, meanwhile promoting cutaneous regeneration, which formed new skin with no inflammation within a 10 day treatment. These results demonstrate the potential application of this self-healing hydrogel for the integrated therapy of antibiosis and tissue regeneration.

Abstract
AIM To evaluate the efficacy and safety of collagen biomaterial application during the 4-week follow-up of patients with diabetic foot syndrome. MATERIAL AND METHODS 75 patients with diabetic foot (Wagner II (69.3%) and III (30.7%)) aged 30-80 years were included in the multicenter study, among them were 50.7% with the wound unhealed for 1.5-6 months and 49.3% over 6-48 months. Patients were randomized into 2 groups: 1) standard therapy (n=37), 2) the additional use of the collagen material Collost (n=38). Observation period was at least 4 weeks for each patient. The size of ulcers, results of general and biochemical blood tests, oximetry, microbiological testing, ultrasound of lower extremities vessels as well as a detailed medical history, social and functional status, level of cardiovascular comorbidity and ongoing therapy were estimated. RESULTS Additional use of a collagen biomaterial has led to a significant reduction ulcers of all sizes from 13.5 to 2.1 cm2 (in the comparison group - from 12.5 to 7 cm2). The best dynamics have been registered in Wagner II (4.4-fold average wound area regress in Collost group, from 8.8 to 2.0 cm2; average wound area regress by 1.8 times, from 10 to 5.6 cm2 in the comparison group) than in Wagner III group (in the main group from 55 to 21.3 cm2; in the control group from 36 to 32.4 cm2) and in ulcers existing less than 6 months. Treatment with biological material Collost within standard therapy after 4 weeks led to increase of complete epithelialization by 2.6% (21.1% as compared to 14.7%), while decreasing the frequency of ineffective treatment by 4.1 (7.9% in primary and 32.4% in the comparison group). CONCLUSION We have proved the efficacy and safety of collagen biomaterial topical application in a diabetic foot syndrome treatment.
