Abstract
Mesenchymal stem cells (MSCs) have the potential to differentiate into multi-lineage cells, suggesting their future applicability in regenerative medicine and biotechnology. The immunomodulatory properties of MSCs make them a promising replacement therapy in various fields of animal research including in canine atopic dermatitis (AD), a skin disease with 10-15% prevalence. We investigated the immunomodulatory effects of MSCs in an experimental canine AD model induced by Dermatophagoides farinae extract ointment. Canine adipose tissue-derived MSCs (cAT-MSCs) were differentiated into mesodermal cell lineages at the third passage. Alterations in immunomodulatory factors in control, AD, and MSC-treated AD groups were evaluated using flow cytometric analysis, enzyme-linked immunosorbent assay, and quantitative reverse transcription PCR. In the MSC-treated AD group, the number of eosinophils decreased, and the number of regulatory T cells (Tregs) increased compared to those in the AD group. In addition, the immunoglobulin E (IgE) and prostaglandin E2 levels were reduced in the MSC-treated AD group compared to those in the AD group. Furthermore, the filaggrin, vascular endothelial growth factor, and interleukin-5 gene expression levels were relatively higher in the MSC-treated AD group than in the AD group, however, not significantly. cAT-MSCs exerted immunomodulatory effects in an AD canine model via a rebalancing of type-1 and -2 T helper cells that correlated with increased levels of Tregs, IgE, and various cytokines.

BIOENGINEERING (BASEL, SWITZERLAND) 2023; 10:bioengineering10010102. [PMID: 36671674 PMCID: PMC9855129 DOI: 10.3390/bioengineering10010102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 12/29/2022] [Accepted: 01/06/2023] [Indexed: 01/15/2023]
Abstract
Mesenchymal stem cells (MSCs) hold considerable promise for regenerative medicine. Optimization of the seeding density of mononuclear cells (MNCs) improves the proliferative and differentiation potential of isolated MSCs. However, the underlying mechanism is unclear. We cultured human bone marrow MNCs at various seeding densities (4.0 × 104, 1.25 × 105, 2.5 × 105, 6.0 × 105, 1.25 × 106 cells/cm2) and examined MSC colony formation. At lower seeding densities (4.0 × 104, 1.25 × 105 cells/cm2), colonies varied in diameter and density, from dense to sparse. In these colonies, the proportion of highly proliferative MSCs increased over time. In contrast, lower proliferative MSCs enlarged more rapidly. Senescent cells were removed using a short detachment treatment. We found that these mechanisms increase the purity of highly proliferative MSCs. Thereafter, we compared MSCs isolated under optimized conditions with a higher density (1.25 × 106 cells/cm2). MSCs under optimized conditions exhibited significantly higher proliferative and differentiation potential into adipocytes and chondrocytes, except for osteocytes. We propose the following conditions to improve MSC quality: (1) optimizing MNC seeding density to form single-cell colonies; (2) adjusting incubation times to increase highly proliferative MSCs; and (3) establishing a detachment processing time that excludes senescent cells.

Abstract
The introduction of new regenerative therapeutic modalities in the veterinary practice has recently picked up a lot of interest. Stem cells are undifferentiated cells with a high capacity to self-renew and develop into tissue cells with specific roles. Hence, they are an effective therapeutic option to ameliorate the ability of the body to repair and engineer damaged tissues. Currently, based on their facile isolation and culture procedures and the absence of ethical concerns with their use, mesenchymal stem cells (MSCs) are the most promising stem cell type for therapeutic applications. They are becoming more and more well-known in veterinary medicine because of their exceptional immunomodulatory capabilities. However, their implementation on the clinical scale is still challenging. These limitations to their use in diverse affections in different animals drive the advancement of these therapies. In the present article, we discuss the ability of MSCs as a potent therapeutic modality for the engineering of different animals' tissues including the heart, skin, digestive system (mouth, teeth, gastrointestinal tract, and liver), musculoskeletal system (tendons, ligaments, joints, muscles, and nerves), kidneys, respiratory system, and eyes based on the existing knowledge. Moreover, we highlighted the promises of the implementation of MSCs in clinical use in veterinary practice.

How to maintain and transport equine adipose tissue for isolating mesenchymal stem cells? BMC Vet Res 2022; 18:284. [PMID: 35864533 PMCID: PMC9306088 DOI: 10.1186/s12917-022-03379-1] [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: 01/17/2022] [Accepted: 07/11/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Adipose tissue (AT) is one of the most important mesenchymal stem cell (MSC) sources because of its high quantities, availability and ease of collection. After being collected samples, they should be transported to a laboratory for stem cell (SC) isolation, culture and expansion for future clinical application. Usually, laboratories are distant from animal husbandry centers; therefore, it is necessary to provide suitable conditions for adipose tissue transportation, such that adipose-derived MSCs are minimally affected. In the current study, the impact of tissue maintenance under different conditions on MSCs derived from these tissues was evaluated. We aimed at finding suitable and practical transportation methods in which ASCs go through the slightest changes. RESULTS In the current study, after being collected, equine AT was randomized into eight groups: four samples were maintained in stem cell culture media at 25 οC and 4 οC for 6 and 12 hrs. as transportation via SC media groups. Three samples were frozen at three different temperatures (- 20, - 75 and - 196 οC) as cryopreserved groups; these samples were defrosted 1 week after cryopreservation. Fresh and unfrozen AT was evaluated as a control group. The tissue samples were then initiated into enzymatic digestion, isolation and the culturing of SCs. Cells at passage three were used to evaluate the ability to form colonies, proliferation rate, plotting of the cell growth curve, and viability rate. All experiments were performed in triplicate. Stem cell isolation was successful in all groups, although purification of SCs from the first series of cryopreservation at - 196 οC and two series of - 20 οC was unsuccessful. There was no significant difference between the surface area of colonies in all groups except for - 20 οC. The growth rate of transportation via stem cell media at 25 οC for 6 hrs. was similar to that of the control group. MTT analysis revealed a significant difference between 25 οC 12 hrs. Group and other experimental groups except for control, 4 οC 12 hrs. and - 196 οC group. CONCLUSION Data have shown freezing at - 75 οC, transportation via stem cell media at 4 οC for 12 hrs. and 25 οC for 6 hrs. are acceptable tissue preservation and transportation methods due to minor effects on MSCs features.

Abstract
The incidence of nonalcoholic steatohepatitis-related liver cirrhosis is increasing. We used a steatohepatitis murine model fed a choline-deficient, l-amino acid-defined (CDAA) diet with a single injection of carbon tetrachloride (CCl4) to evaluate the efficacy of trans-portal hepatic infusion of bone marrow-derived mesenchymal stem cells (BMSCs) for liver fibrosis, liver steatosis, and oxidative stress. Mice were fed a CDAA diet and injected with a single intraperitoneal dose of CCl4 (0.5 ml/kg) after 4 weeks of CDAA diet. After 12 weeks of CDAA diet, 1 × 106 luciferase-positive syngeneic BMSCs (Luc-BMSCs) were infused into the animal spleen. An in vivo imaging system was used to confirm Luc-BMSC accumulation in the liver via the portal vein, and at 4 weeks after infusion, we compared liver fibrosis, liver steatosis, and oxidative stress. After the BMSC-infusion, serum albumin and serum total bilirubin were significantly improved. Liver fibrosis assessed by Sirius red staining, α-smooth muscle actin protein, and collagen 1A1 mRNA expression was significantly suppressed. Furthermore, liver steatosis area was significantly lower, the 8-hydroxy-2'-deoxyguanosine-positive cells were significantly fewer, and superoxide dismutase 2 protein expression of the liver was significantly increased. In conclusion, our data confirmed the efficacy of trans-portal hepatic infusion of BMSCs in a steatohepatitis murine model.

Abstract
Liver transplantation is the only radical treatment for decompensated cirrhosis, but its use is limited owing to a shortage of donors; hence, there is an urgent need for new treatments. Previously, we developed a liver-regeneration therapy using autologous bone marrow-derived mesenchymal stem cells (BMSCs), which is under clinical investigation. Cell-cell interactions between BMSCs and macrophages (Mφs) participate in the improvement of liver function and alleviation of liver fibrosis, although the associated mechanisms have not been elucidated. Therefore, in this study, we investigated phenotypic changes in Mφs caused by interactions with BMSCs, as well as the underlying mechanisms. Co-culturing lipopolysaccharide (LPS)-stimulated murine bone marrow-derived Mφs (BMDMs) with BMSCs substantially upregulated matrix metalloproteinase 9 (Mmp9), Mmp12, and Mmp13 expression, and downregulated tumor necrosis factor alpha (Tnfα) expression. To identify humoral factors involved in phenotypic changes occurring in Mφs, microarray analysis was performed with microRNAs (miRNAs) derived from extracellular vesicles in the supernatant of co-cultured BMSCs and LPS-stimulated BMDMs. We found that miR-6769b-5p was highly expressed and that transfecting miR-6769b-5p mimic upregulated MMP9 in LPS-stimulated BMDMs and downregulated Tnfα and interleukin-1 beta (Il-1β). MiR-6769b-5p expression in BMDMs was decreased by LPS stimulation but was increased by co-culture with BMSCs. Microarray and pathway analyses of gene expression in LPS-stimulated, miR-6769b-5p-transfected BMDMs revealed changes in the eukaryotic initiation factor 2-signaling pathway and decreased the expression of activating transcription factor 4 (Atf4). LPS-stimulated BMDMs exhibited increased MMP9 expression and decreased the expression of Tnfα and Il-1β by ATF4 knockdown. These findings indicate that upregulating miR-6769b-5p in BMDMs induced a fibrolytic phenotype, where MMP9 was highly expressed and inflammatory cytokine expression was decreased by the suppression of ATF4 expression. These findings imply that regulating miR-6769b-5p or ATF4 expression in BMDMs may be helpful for treating chronic liver disease.

Abstract
Regenerative medicine is a branch of medicine that develops methods to grow, repair, or replace damaged or diseased cells, organs or tissues. It has gained significant momentum in recent years. Stem cells are undifferentiated cells with the capability to self—renew and differentiate into tissue cells with specialized functions. Stem cell therapies are therefore used to overcome the body's inability to regenerate damaged tissues and metabolic processes after acute or chronic insult. The concept of stem cell therapy was first introduced in 1991 by Caplan, who proposed that massive differentiation of cells into the desired tissue could be achieved by isolation, cultivation, and expansion of stem cells in in vitro conditions. Among different stem cell types, mesenchymal stem cells (MSC) currently seem to be the most suitable for therapeutic purposes, based on their simple isolation and culturing techniques, and lack of ethical issues regarding their usage. Because of their remarkable immunomodulatory abilities, MSCs are increasingly gaining recognition in veterinary medicine. Developments are primarily driven by the limitations of current treatment options for various medical problems in different animal species. MSCs represent a possible therapeutic option for many animal diseases, such as orthopedic, orodental and digestive tract diseases, liver, renal, cardiac, respiratory, neuromuscular, dermal, olfactory, and reproductive system diseases. Although we are progressively gaining an understanding of MSC behavior and their mechanisms of action, some of the issues considering their use for therapy are yet to be resolved. The aim of this review is first to summarize the current knowledge and stress out major issues in stem cell based therapies in veterinary medicine and, secondly, to present results of clinical usage of stem cells in veterinary patients.

Abstract
Cell adhesion is essential for survival, it plays important roles in physiological cell functions, and it is an innovative target in regenerative medicine. Among the molecular interactions and the pathways triggered during cell adhesion, the binding of cluster of differentiation 44 (CD44), a cell-surface glycoprotein involved in cell-cell interactions, to hyaluronic acid (HA), a major component of the extracellular matrix, is a crucial step. Cell therapy has emerged as a promising treatment for advanced liver diseases; however, so far, it has led to low cell engraftment and limited cell repopulation of the target tissue. Currently, different strategies are under investigation to improve cell grafting in the liver, including the use of organic and inorganic biomatrices that mimic the microenvironment of the extracellular matrix. Hyaluronans, major components of stem cell niches, are attractive candidates for coating stem cells since they improve viability, proliferation, and engraftment in damaged livers. In this review, we will discuss the new strategies that have been adopted to improve cell grafting and track cells after transplantation.
