Abstract
Inflammatory bowel disease (IBD) is a collective term for a group of chronic inflammatory enteropathies which are characterized by intestinal inflammation and persistent or frequent gastrointestinal signs. This disease affects more than 3.5 million humans worldwide and presents some similarities between animal species, in particular, dogs and cats. Although the underlying mechanism that triggers the disease is not yet well understood, the evidence suggests a multifactorial etiology implicating genetic causes, environmental factors, microbiota imbalance, and mucosa immune defects, both in humans and in dogs and cats. Conventional immunomodulatory drug therapies, such as glucocorticoids or immunosuppressants, are related with numerous adverse effects that limit its long-term use, creating the need to develop new therapeutic strategies. Mesenchymal stromal cells (MSCs) emerge as a promising alternative that attenuates intestinal inflammation by modulating inflammatory cytokines in inflamed tissues, and also due to their pro-angiogenic, anti-apoptotic, anti-fibrotic, regenerative, anti-tumor, and anti-microbial potential. However, this therapeutic approach may have important limitations regarding the lack of studies, namely in veterinary medicine, lack of standardized protocols, and high economic cost. This review summarizes the main differences and similarities between human, canine, and feline IBD, as well as the potential treatment and future prospects of MSCs.

Abstract
Intrauterine adhesion (IUA), also referred to as Asherman Syndrome (AS), results from uterine trauma in both pregnant and nonpregnant women. The IUA damages the endometrial bottom layer, causing partial or complete occlusion of the uterine cavity. This leads to irregular menstruation, infertility, or repeated abortions. Transcervical adhesion electroreception (TCRA) is frequently used to treat IUA, which greatly lowers the prevalence of adhesions and increases pregnancy rates. Although surgery aims to disentangle the adhesive tissue, it can exacerbate the development of IUA when the degree of adhesion is severer. Therefore, it is critical to develop innovative therapeutic approaches for the prevention of IUA. Endometrial fibrosis is the essence of IUA, and studies have found that the use of different types of mesenchymal stem cells (MSCs) can reduce the risk of endometrial fibrosis and increase the possibility of pregnancy. Recent research has suggested that exosomes derived from MSCs can overcome the limitations of MSCs, such as immunogenicity and tumorigenicity risks, thereby providing new directions for IUA treatment. Moreover, the hydrogel drug delivery system can significantly ameliorate the recurrence rate of adhesions and the intrauterine pregnancy rate of patients, and its potential mechanism in the treatment of IUA has also been studied. It has been shown that the combination of two or more therapeutic schemes has broader application prospects; therefore, this article reviews the pathophysiology of IUA and current treatment strategies, focusing on exosomes combined with hydrogels in the treatment of IUA. Although the use of exosomes and hydrogels has certain challenges in treating IUA, they still provide new promising directions in this field.

Abstract
The occurrence of chronic wounds is a major global health issue. These wounds are difficult to heal as a result of disordered healing mechanisms. The most common types of chronic wounds are diabetic ulcers, pressure ulcers, arterial/venous ulcers and nonhealing surgical wounds. Although bacteria are an important cause of chronic nonhealing wounds, fungi also play a substantial role in them. The fungal infection rate varies with different chronic wound types, but overall, the prevalence of fungi is extremely underestimated in the clinical treatment and management of chronic wounds. Wounds and ulcers can be colonized by host cutaneous, commensal or environmental fungi and evolve into local infections, causing fungemia as well as invasive fungal disease. Furthermore, the fungi involved in nonhealing wound-related infections help commensal bacteria resist antibiotics and the host immune response, forcing wounds to become reservoirs for multiresistant species, which are considered a potential key factor in the microbial bioburden of wounds and ulcers. Fungi can be recalcitrant to the healing process. Biofilm establishment is the predominant mechanism of fungal resistance or tolerance to antimicrobials in chronic nonhealing wounds. Candida albicans yeast and Trichophyton rubrum filamentous fungi are the main fungi involved in chronic wound infection. Fungal species diversity and drug resistance phenotypes in different chronic nonhealing wound types will be emphasized. In this review, we outline the latest research on fungi in chronic wounds and discuss challenges and future perspectives related to diagnosing and managing chronic wounds.

Comparative Study Between the Mini-Open (≤2.5 Cm) Approach and Conventional Open Lateral Approach in the Surgical Treatment of Radial Head Fractures. J Pain Res 2022; 15:3413-3422. [PMID: 36320225 PMCID: PMC9618242 DOI: 10.2147/jpr.s374599] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Accepted: 10/18/2022] [Indexed: 11/07/2022] Open
Abstract
Purpose The conventional lateral approach is widely used to treat radial head fractures with screws. However, the traditional incision may have shortcomings, including excessive exposure and significant scarring. We propose an innovative method – a mini-open lateral approach of less than 2.5 cm for surgical treatment of radial head fractures with screws. Methods From Jan 2017 to Dec 2020, 34 patients diagnosed with closed radial head fracture were treated with open reduction and internal fixation (ORIF) in this study. The novel group (mini-open group) included 15 patients, and the other 19 patients were in the traditional group. The time of operation and the blood loss during operation were recorded. Postoperative clinical outcomes and radiographic results were recorded and compared between the two groups. The range of motion (ROM) in the elbow, the Visual Analogue Scale (VAS), the Mayo Elbow Performance Score (MEPS), Rating Scale of the American Shoulder and Elbow Surgeons (ASES), and the Shortened Disabilities of the Arm, Shoulder and Hand Questionnaire (Q-DASH) score and complications, such as wound infection, vascular and nerve damage, and fragment redisplacement were observed in the two groups. Results In the comparison between the two groups, there was no significant difference in age, sex, cause of radial head fracture, or other basic information. The operation time, intraoperative blood loss, and VAS score at 3 days postoperation were significantly reduced in the novel group (p < 0.05). The follow-up results showed that there was no significant difference in MEPS, ASES, or Q-DASH scores between the two groups. Conclusion The mini-open approach reduced intraoperative blood loss, shortened operation time, relieved patient pain, and achieved a satisfactory postoperative clinical result, which demonstrates that the novel approach is a safe and effective option for treating radial head fractures.

Effect of Allogeneic Oral Mucosa Mesenchymal Stromal Cells on Equine Wound Repair. Vet Med Int 2021; 2021:5024905. [PMID: 34950446 PMCID: PMC8692048 DOI: 10.1155/2021/5024905] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Revised: 10/14/2021] [Accepted: 11/25/2021] [Indexed: 11/17/2022] Open
Abstract
Objective To assess the clinical value and safety of the application of allogeneic equine oral mucosa mesenchymal stromal cells (OM-MSCs) to wounds. Animals. 8 healthy adult horses without front limb skin lesions or musculoskeletal disease. Procedures. Stem cells were isolated from the oral mucosa of a donor horse. Horses were subjected to the creation of eight full-thickness cutaneous wounds, two on each distal forelimb (FL) and two on both sides of the thorax (TH). Each wound was subjected to one out of four treatments: no medication (T1), hyaluronic acid- (HA-) gel containing OM-MSC (T2), HA-gel containing OM-MSC secretome (T3), and HA-gel alone (T4). Gross macroscopic evaluation and laser digital photographic documentation were regularly performed to allow wound assessment including wound surface area. Full-thickness skin punch biopsy was performed at each site before wound induction (D0, normal skin) and after complete wound healing (D62, repaired skin). Results All wounds healed without adverse effect at D62. Distal limb wounds are slower to heal than body wounds. OM-MSC and its secretome have a positive impact on TH wound contraction. OM-MSC has a positive impact on the contraction and epithelialization of FL wounds. No significant difference between wound sites before and after treatment was noted at histological examination. Conclusion and Clinical Relevance. Using horse cells harvested from oral mucosa is a feasible technique to produce OM-MSC or its secretome. The gel produced by the combination of these biologic components with HA shows a positive impact when applied during the early stage of wound healing.

Abstract
Wound management poses a considerable economic burden on the global healthcare system, considering the impacts of wound infection, delayed healing and scar formation. To this end, multifunctional dressings based on hydrogels have been developed to stimulate skin healing. Herein, we describe the design, fabrication, and characterization of a sprayable hydrogel-based wound dressing loaded with cerium oxide nanoparticles (CeONs) and an antimicrobial peptide (AMP), for combined reactive oxygen species (ROS)-scavenging and antibacterial properties. We adopted a mussel-inspired strategy to chemically conjugate gelatin with dopamine motifs and prepared a hydrogel dressing with improved binding affinity to wet skin surfaces. Additionally, the release of AMP from the hydrogel demonstrated rapid release ablation and contact ablation against four representative bacterial strains, confirming the desired antimicrobial activities. Moreover, the CeONs-loaded hydrogel dressing exhibited favorable ROS-scavenging abilities. The biocompatibility of the multifunctional hydrogel dressing was further proven in vitro by culturing with HaCaT cells. Overall, the benefits of the developed hydrogel wound dressing, including sprayability, adhesiveness, antimicrobial activity, as well as ROS-scavenging and skin-remodeling ability, highlight its promissing translational potentials in wound management. STATEMENT OF SIGNIFICANCE: Various hydrogel-based wound-dressing materials have been developed to stimulate wound healing. However, from the clinical perspective, few of the current wound dressings meet all the intended multifunctional requirements of preventing infection, promoting rapid wound closure, and minimizing scar formation, while simultaneously offering the convenience of application. In the current study, we adopted a mussel-inspired strategy to functionalize the GelMA hydrogels with DOPA to fabricate GelMA-DOPA hydrogel which exhibited an enhanced binding affinity for wound surfaces, AMP HHC-36 and CeONs are further encapsulated into the GelMA-DOPA hydrogel to confer the hydrogel wound dressing with antimicrobial and ROS-scavenging abilities. The GelMA-DOPA-AMP-CeONs dressing offered the benefits of sprayability, adhesiveness, antimicrobial activity, as well as ROS-scavenging and skin-remodeling ability, which might address the therapeutic and economic burdens associated with chronic wound treatment and management.

Abstract
Mesenchymal stem cells are multipotent cells, with capacity for self-renewal and differentiation into tissues of mesodermal origin. These cells are possible therapeutic agents for autoimmune disorders, since they present remarkable immunomodulatory ability.The increase of immune-mediated diseases in veterinary medicine has led to a growing interest in the research of these disorders and their medical treatment. Conventional immunomodulatory drug therapy such as glucocorticoids or other novel therapies such as cyclosporine or monoclonal antibodies are associated with numerous side effects that limit its long-term use, leading to the need for developing new therapeutic strategies that can be more effective and safe.The aim of this review is to provide a critical overview about the therapeutic potential of these cells in the treatment of some autoimmune disorders (canine atopic dermatitis, feline chronic gingivostomatitis, inflammatory bowel disease and feline asthma) compared with their conventional treatment.Mesenchymal stem cell-based therapy in autoimmune diseases has been showing that this approach can ameliorate clinical signs or even cause remission in most animals, with the exception of canine atopic dermatitis in which little to no improvement was observed.Although mesenchymal stem cells present a promising future in the treatment of most of these disorders, the variability in the outcomes of some clinical trials has led to the current controversy among authors regarding their efficacy. Mesenchymal stem cell-based therapy is currently requiring a deeper and detailed analysis that allows its standardization and better adaptation to the intended therapeutic results, in order to overcome current limitations in future trials.

Abstract
BACKGROUND A major global health issue is the existence of chronic wounds. Appropriate diagnosis and treatment is essential to promote wound healing and prevent further complications. Traditional methods for treatment and diagnosis of chronic wounds have shown to be of limited effectiveness. Therefore, there is a need for the development of diagnostic and therapeutic innovations in chronic wound care. OBJECTIVE This mini-review aims to provide insight in the current knowledge of the wound healing process and the deficiencies encountered in chronic wounds, which provides a basis for the development of innovations in chronic wound care. Furthermore, promising diagnostic and therapeutic innovations will be highlighted. METHODS Literature was searched for recent articles (=<10 years) describing the current knowledge about the wound healing process and chronic wounds. The most promising diagnostic and therapeutic innovations were gathered from articles published in the past 5 years. RESULTS/CONCLUSION Wound healing is a well-organized process consisting of four phases: coagulation, inflammation, proliferation and wound remodelling. Chronic wounds often stagnate in the inflammatory phase and/or experience an impaired proliferative phase. This mini-review has demonstrated that increased knowledge about the processes involved in wound healing has paved the way for the development of new diagnostic tools and treatments for chronic wounds. Increased knowledge about bacterial invasion and infection in has encouraged researchers to develop diagnostic tools to help clinicians detect these phenomena appropriately and in time. Other researchers have shown that they are able to design/extract biochemical compounds that intervene in the disrupted healing processes in chronic wounds.

Abstract
Scarring is a result of the wound healing response and causes tissue dysfunction after injury. This process is readily evident in the skin, but also occurs internally across organ systems in the form of fibrosis. Stem cells are crucial to the innate tissue healing response and, as such, present a possible modality to therapeutically promote regenerative healing while minimizing scaring. In this review, the cellular basis of scaring and fibrosis is examined. Current stem cell therapies under exploration for skin wound healing and internal organ fibrosis are discussed. While most therapeutic approaches rely on the direct application of progenitor-type cells to injured tissue to promote healing, novel strategies to manipulate the scarring response are also presented. As our understanding of developmental and stem cell biology continues to increase, therapies to encourage regeneration of healthy functional tissue after damage secondary to injury or disease will continue to expand.

Abstract
Jellyfish grow rapidly and have a strong regenerative ability, indicating that they may express high levels of growth factors. Therefore, the aim of this research was to isolate the growth-promoting components from the jellyfish Cyanea capillata (C. capillata) and to further explore the underlying mechanisms. In this study, we first isolated and identified a novel polypeptide from C. capillata tentacles using size-exclusion chromatography followed by reverse-phase HPLC. This peptide, consisting of 58 amino acids (MW 5782.9 Da), belonged to the granulin (GRN) family of growth factors; thus, we named it Cyanea capillata granulin-1 (CcGRN-1). Second, using CCK-8 assay and flow cytometry, we verified that CcGRN-1 at the 0.5 μg/ml concentration could promote cell proliferation and increase the expression of cell-cycle proteins (CyclinB1 and CyclinD1). Third, signaling pathways studies showed that CcGRN-1 could activate the PI3K/Akt- and ERK1/2 MAPK-signaling pathways but not the JNK MAPK- or NF-κB-signaling pathways. Subsequently, we further confirmed that the CcGRN-1-induced cell proliferation and migration were associated only with the ERK1/2 MAPK-signaling pathway. Considering all of these factors, CcGRN-1, as the first jellyfish-derived GRN homologue, possesses growth-promoting properties and may be a candidate for novel therapeutics to promote human wound healing in unfavorable conditions.

Abstract
The molecular and cellular level reaches of the metabolic dysregulations that characterize diabetes are yet to be fully discovered. As mechanisms underlying management of reactive oxygen species (ROS) gain interest as crucial factors in cell integrity, questions arise about the role of redox cues in the regulation and maintenance of bone marrow-derived multipotent stromal cells (BMSCs) that contribute to wound healing, particularly in diabetes. Through comparison of BMSCs from wild-type and diabetic mice, with a known redox and metabolic disorder, we found that the cytoprotective nuclear factor erythroid-related factor 2 (Nrf2)/kelch-like erythroid cell-derived protein 1 (Keap1) pathway is dysregulated and functionally insufficient in diabetic BMSCs (dBMSCs). Nrf2 is basally active, but in chronic ROS, we found irregular inhibition of Nrf2 by Keap1, altered metabolism, and limited BMSC multipotency. Forced upregulation of Nrf2-directed transcription, through knockdown of Keap1, restores redox homeostasis. Normalized Nrf2/Keap1 signaling restores multipotent cell properties in dBMSCs through Sox2 expression. These restored BMSCs can resume their role in regenerative tissue repair and promote healing of diabetic wounds. Knowledge of diabetes and hyperglycemia-induced deficits in BMSC regulation, and strategies to reverse them, offers translational promise. Our study establishes Nrf2/Keap1 as a cytoprotective pathway, as well as a metabolic rheostat, that affects cell maintenance and differentiation switches in BMSCs.

Abstract
Cell transplantation strategies represent a potential therapeutic approach towards repair of congenital vaginal agenesis. In this study, the efficacy and mechanisms of action of treatment with human umbilical cord-derived mesenchymal stem cells (UC-MSCs) on vaginal regeneration was explored. UC-MSC transplantation alone, small intestinal submucosal (SIS) grafting alone, and a combination of UC-MSC transplantation/SIS grafting were performed with a vaginal defect rat model. Histological analyses of tissue sections were subsequently performed. UC-MSCs promoted the recovery of keratinizing squamous epithelium and papillae to nearly the same levels as in normal tissue. Of the treatments tested, UC-MSC transplantation showed optimal performance in inhibiting collagen deposition and accelerating the synthesis of elastin to maintain tissue elasticity. UC-MSC treatment also increased Cyclin D1, Ki67, and CD31 expression as assessed by immunohistochemistry. We also investigated the effects of UC-MSC secretions on keratinocytes in a co-culture model. UC-MSCs significantly stimulated vaginal tissue repair by promoting vaginal epithelium regeneration via paracrine factors but not by exploiting their keratinocyte differentiation potential. Further, UC-MSCs facilitated epithelial cell viability and promoted cell cycle progression via the AKT/GSK3β/Cyclin D1 pathway. These results indicate that UC-MSC transplantation is a feasible approach for vaginal tissue regeneration.

Abstract
The osteogenic differentiation of mesenchymal stem cells (MSCs) is governed by multiple mechanisms. Growing evidence indicates that ubiquitin-dependent protein degradation is critical for the differentiation of MSCs and bone formation; however, the function of ubiquitin-specific proteases, the largest subfamily of deubiquitylases, remains unclear. Here, we identify USP34 as a previously unknown regulator of osteogenesis. The expression of USP34 in human MSCs increases after osteogenic induction while depletion of USP34 inhibits osteogenic differentiation. Conditional knockout of Usp34 from MSCs or pre-osteoblasts leads to low bone mass in mice. Deletion of Usp34 also blunts BMP2-induced responses and impairs bone regeneration. Mechanically, we demonstrate that USP34 stabilizes both Smad1 and RUNX2 and that depletion of Smurf1 restores the osteogenic potential of Usp34-deficient MSCs in vitro Taken together, our data indicate that USP34 is required for osteogenic differentiation and bone formation.

Abstract
![]()
Introduction:
Diabetic burn wounds and ulcers are significant complications of diabetic patients. The aim of this study is to investigate the use of platelet rich-plasma (PRP) and/or keratinocyte-like cells (KLCs) in diabetic thermal wound rat model and to evaluate EGF, FGF-2, TGF-β1, COL1α2, MCP-1 and VEGF-α as wound healing markers at gene expression level.
Method:
In this study, we used adipose tissue as the source of mesenchymal stem cells (MSCs) and differentiated MSCs into KLCs. KLCs were characterized and transferred to the burn areas on the dorsum of streptozotocine (STZ)-induced diabetic rats. We prepared PRP from rat blood and evaluated its effect alone or in combination with KLCs. On 3rd, 7th, 10th and 14th days after treatment, wound areas were measured and biopsy samples were excised from the wound areas of the KLCs and/or PRP-treated and untreated diabetic rats to analyze gene expression levels of wound healing markers by qPCR.
Results:
We observed that, wound contraction started earlier in the PRP and/or KLCs-treated groups in comparison to the control group. However, PRP and KLCs when applied in combination showed additive affect in wound healing. In all groups treated with KLCs and/or PRP, the gene expression levels of evaluated growth factors and COL1α2 increased, while MCP-1 levels decreased when compared to the untreated diabetic rats. In addition, the most prominent difference in qPCR results belongs to combined PRP and KLCs-treated group.
Conclusion:
We demonstrated that applying PRP and KLCs in combination has a greater potential for treatment of diabetic burn wounds.

Abstract
Adipose-derived mesenchymal stem cells (ADSCs) possess a liver regeneration capacity and immunosuppressive activity and hold promise in autologous cell-based technology. This study aimed to determine whether autologous ADSCs can improve outcomes in the rat reduced size liver transplantation model. Allogeneic 50% orthotopic liver transplantation followed by administration of autologous ADSCs delivered into the portal vein system was conducted in LEW donor rats and BN recipient rats with phosphate buffered solution (PBS) infusion used as the control. Liver grafts and recipient serum were obtained. We assessed histopathology, regeneration, apoptosis, serum liver enzymes, serum cytokines, and circulating regulatory T cells (Tregs) on postoperative day (POD) 7 and 14. It was found that ADSCs significantly reduced acute rejection and improved the allograft's survival times (median, 24days). Liver function, as assessed by the levels of alanine aminotransferase, aspartate aminotransferase, total bilirubin, as well as liver apoptosis was significantly alleviated in the ADSC group compared with the control group. In addition, ADSC therapy markedly promoted the expression of PCNA in the allograft. Furthermore, levels of interleukin (IL)-10 and transforming growth factor (TGF)-β1 were significantly elevated, whereas those of IL-2 and IL-17 levels were significantly reduced in the ADSC group when compared to the control group. Moreover, flow cytometry analysis revealed that peripheral Tregs had been significantly increased by the infusion of ADSCs. These results demonstrate that implanted autologous ADSCs improve allogeneic reduced size liver allograft outcomes by attenuating acute rejection and reducing inflammatory responses, as well as enhancing liver regeneration.

Abstract
Venous leg ulcers (VLU) are a prevalent and reoccurring type of complicated wound, turning as a considerable public healthcare issue, with critical social and economic concern. There are both medical and surgical therapies to treat venous leg ulcers; however, a cure does not yet exist. Mesenchymal stem cells (MSC) are capable and proved of accelerating wound healing in vivo and their study with human chronic wounds is currently awaited. MSCs are a promising source of adult progenitor cells for cellular therapy and have been demonstrated to differentiate into various mesenchymal cell lineages. They have a crucial and integral role in native wound healing by regulating immune response and inflammation. Improved understanding of the cellular and molecular mechanisms at work in delayed wound healing compels to the development of cellular therapy in VLU. This review focuses on the current treatment option of VLU and further emphasizing the role of MSCs in accelerating the healing process. With further understanding of the mechanism of action of these cells in wound improvement and, the involvement of cytokines can also be revealed that could be used for the therapeutic purpose for VLU healing. Clinical uses of MSCs have been started already, and induced MSCs are surely a promising tool or compelling therapy for VLU.

Abstract
Amnion-derived mesenchymal stem cells (AMSC) are a promising tool in regenerative medicine. Here we evaluated the utility of Matrigel and Matriderm as carrier for the topical application of AMSC to mice skin wounds. In both application forms, AMSC promoted neovascularization of the wound area. Matrigel proved as excellent matrix for AMSC and immigrating mouse cells, but the solid Matriderm enabled a more adequate positioning of AMSC into the wound. Although AMSC did not attach to Matriderm, they reliably induced wound reduction. Thus, a combined administration of AMSC/Matriderm could be beneficial to potentiate the encouraging effects on wound healing.

Abstract
Plasmacytoid dendritic cells (pDCs) are rare central regulators of antiviral immunity and unsurpassed producers of interferon-α (IFN-α). Despite their crucial role as a link between innate and adaptive immunity, little is known about the modulation of pDC differentiation by other bone marrow (BM) cells. In this study, we investigated the modulation of pDC differentiation in Flt-3 ligand (Flt3L)-supplemented BM cultures, using highly purified mesenchymal stem cells (MSCs) that were FACS-isolated from murine BM based on surface marker expression and used after in vitro expansion. Initial analysis revealed an almost complete inhibition of BM-derived pDC expansion in the presence of >2% MSC. This inhibition was cell contact-dependent and soluble factor-independent, as indicated by trans-well experiments. The abrogation of functional pDC development by MSCs was confirmed after TLR9 stimulation, revealing a complete, contact-dependent suppression of the IFN-a producing capacity of pDCs in Flt3L MSC BM co-cultures. MSC selectively inhibited pDC development in contrast to myeloid DC development, as indicated by the significantly increased numbers of myeloid DC in Flt3L-supplemented BM cultures. The absence of significant MSC-mediated inhibitory effects on myeloid DC differentiation was confirmed by additional experiments in GM-CSF/IL-4-supplemented BM cultures. In summary, we describe a novel contact-dependent immunomodulatory mechanism of MSC that targets the BM-derived expansion of functional pDCs.
