Extracellular Vesicles Derived From Canine Mesenchymal Stromal Cells in Serum Free Culture Medium Have Anti-inflammatory Effect on Microglial Cells. Front Vet Sci 2021; 8:633426. [PMID: 33996963 PMCID: PMC8113404 DOI: 10.3389/fvets.2021.633426] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Accepted: 03/24/2021] [Indexed: 12/13/2022] Open
Abstract
Mesenchymal stem/stromal cells (MSCs) have been used as cell sources for treating dogs with naturally-occurring diseases. Extracellular vesicles (EVs) derived from MSCs are now recognized as pivotal to modulating the immune response and supporting tissue repair. Manufacture of MSC-EVs for clinical application mandates removal of the xeno-proteins, including fetal bovine serum. The objective of this study was to examine whether canine MSCs survived and secreted EVs in serum-free medium (SFM) conditions and to assess the immunomodulatory effect of EVs in vitro. Canine MSCs were found to survive and secrete EVs under SFM conditions. The surface markers of MSCs in the SFM were similar to MSCs in complete culture medium. Canine MSC-EVs had a diameter of ~300 nm and were positive for EV markers. MSC-derived EVs from the serum-free condition reduced the levels of IL-1β by BV-2 cells in response to LPS stimulation. These results warrant further studies of the use of SFM for producing EVs derived from canine MSCs.

Abstract
We examined the paracrine action of canine mesenchymal stromal cells (MSCs) derived from bone marrow on the survival and differentiation of neural stem cells (NSCs) in
vitro. MSCs were collected from the proximal end of the diaphysis of femur of healthy beagle dogs. The 70–80% confluent MSCs were re-fed with serum-free DMEM. The MSCs were
incubated for 48 hr and the supernatant was collected as the conditioned medium (MSC-CM). The survival rate of NSCs in MSC-CM was significantly greater than in the medium without MSC-CM. The
percentage of differentiated neurons and neurite length in MSC-CM was also significantly higher than in the medium without MSC-CM. These results suggested that canine MSC-CM promotes stem
cell survival and neural differentiation of NSCs.

Abstract
Gene-directed tissue repair offers the clinician, human or veterinary, the chance to enhance cartilage regeneration and repair at a molecular level. Non-viral plasmid vectors have key biosafety advantages over viral vector systems for regenerative therapies due to their episomal integration however, conventional non-viral vectors can suffer from low transfection efficiency. Our objective was to identify and validate in vitro a novel non-viral gene expression vector that could be utilized for ex vivo and in vivo delivery to stromal-derived mesenchymal stem cells (MSCs). Minicircle plasmid DNA vector containing green fluorescent protein (GFP) was generated and transfected into adipose-derived MSCs from three species: canine, equine and rodent and transfection efficiency was determined. Both canine and rat cells showed transfection efficiencies of approximately 40% using minicircle vectors with equine cells exhibiting lower transfection efficiency. A Sox9-expressing minicircle vector was generated and transfected into canine MSCs. Successful transfection of the minicircle-Sox9 vector was confirmed in canine cells by Sox9 immunostaining. This study demonstrate the application and efficacy of a novel non-viral expression vector in canine and equine MSCs. Minicircle vectors have potential use in gene-directed regenerative therapies in non-rodent animal models for treatment of cartilage injury and repair.

Abstract
Canine induced pluripotent stem cells (ciPSCs) are an attractive source for regenerative veterinary medicine, and may also serve as a disease model for human regenerative medicine. Extending the application of ciPSCs from bench to bedside, however, requires resolving many issues. We generated ciPSCs expressing doxycycline-inducible murine Oct3/4 (Pou5f1), Sox2, Klf4, and c-Myc, which were introduced using lentiviral vectors. The resultant ciPSCs required doxycycline to proliferate in the undifferentiated state. Those ciPSC colonies exhibiting basic fibroblast growth factor (bFGF)-dependent proliferation were dissociated into single cells for passaging, and were maintained on a Matrigel-coated dish without feeder cells in a serum-free medium. The established ciPSCs had the ability to differentiate into three germ layers, via formation of embryoid bodies, as well as into cells expressing the same markers as mesenchymal stem cells. These ciPSCs may thus serve as a suitable source of pluripotent stem cell lines for regenerative veterinary medicine, with fewer concerns of contamination from unknown animal components.

Abstract
OBJECTIVES Mesenchymal stem cells (MSCs) represent a powerful tool in regenerative medicine because of their differentiation and migration capacities. Moreover, the immunomodulatory ability of MSCs may be used to develop therapies for the treatment of autoimmune diseases. METHODS In this study, we isolated Flk-1Sca-1 MSCs from bone marrow (bMSCs). Next, we studied their biological characteristics and immunologic functions. We also investigated their effects on graft-versus-host disease (GVHD) associated with allogeneic bone marrow transplantation in mice. RESULTS Flk-1Sca-1 bMSCs were able to differentiate into fat and cartilage cells, indicating that the isolated cells had stem cell properties. They could also suppress alloantigen-induced T cell proliferation in vitro in a dose-dependent manner. Infusion of bMSCs into allogeneic bone marrow-transplanted mice alleviated the lethal GVHD that occurred in control recipient mice. There was significantly lower mortality among the recipients of the Flk-1Sca-1 bMSCs that also ameliorated the clinical symptoms and GVHD histopathology. Beneficial effects on GVHD by Flk-1Sca-1 bMSCs were also observed when MSCs were engineered to express anti-inflammatory cytokines IL-4 and IL-10 and decrease expression of proinflammatory cytokines IFN-γ, TNF-α, and IL-2. CONCLUSION Flk-1Sca-1 bMSCs have stem cell properties and can efficiently ameliorate the GVHD associated with allogeneic bone marrow transplantation in mice.

Abstract
Adipose-derived mesenchymal stem cells (AD-MSCs) are abundant in adipose tissue from animals of all ages, are easily isolated, can differentiate into multi-lineage cells, and have a clinical application. This promising potential may only be achieved if the cells are expanding in a large number while maintaining their stemness in sequential passages. In this study, canine AD-MSCs (cAD-MSCs) were individually isolated from five dogs and subjected to proliferative culture with seven sub-passages. The cells at each sub-passage were characterized for properties associated with multipotent MSCs such as proliferation kinetics, expression of MSCs-specific surface markers, expression of molecules associated with self-renewal and differentiation capabilities into mesodermal lineage cells. Proliferation of the cells plateaued at passage 5 by cumulative population doubling level, while cell doubling time gradually increased with passage. MSCs surface markers (CD44, CD90, and CD105) and molecules (Oct 3/4, Sox-2, Nanog and HMGA2) associated with self-renewal were all expressed in the cells between passages 1 to 6 by RT-PCR. In addition, the cells at passage 1, 3 or 6 underwent adipogenic and chondrogenic differentiation under specific induction conditions. However, the level of adipogenic and chondrogenic differentiation was negatively correlated with the number of sub-passage. The present study suggests that sequential sub-passages affect multipotent properties of cAD-MSCs, which should be considered in their therapeutic application in regenerative medicine.
