Mesenchymal stem cells (MSCs) have been derived from multiple sources of the horse including umbilical cord blood (UCB) and amnion. This work aimed to identify and characterize stem cells from equine amniotic fluid (AF), CB and Wharton's Jelly (WJ). Samples were obtained from 13 mares at labour. AF and CB cells were isolated by centrifugation, while WJ was prepared by incubating with an enzymatic solution for 2 h. All cell lines were cultured in DMEM/TCM199 plus fetal bovine serum. Fibroblast-like cells were observed in 7/10 (70%) AF, 6/8 (75%) CB and 8/12 (66.7%) WJ samples. Statistically significant differences were found between cell-doubling times (DTs): cells isolated from WJ expanded more rapidly (2.0±0.6 days) than those isolated from CB (2.6±1.3 days) and AF (2.3±1.0 days) (P<0.05). Positive von Kossa and Alizarin Red S staining confirmed osteogenesis. Alcian Blue staining of matrix glycosaminoglycans illustrated chondrogenesis and positive Oil Red O lipid droplets staining suggested adipogenesis. All cell lines isolated were positive for CD90, CD44, CD105; and negative for CD34, CD14 and CD45. These findings suggest that equine MSCs from AF, UCB and WJ appeared to be a readily obtainable and highly proliferative cell lines from a uninvasive source that may represent a good model system for stem cell biology and cellular therapy applications in horses. However, to assess their use as an allogenic cell source, further studies are needed for evaluating the expression of markers related to cell immunogenicity.

Osteoarthritis is a significant and costly cause of pain for both humans and horses. The horse has been identified as a suitable model for human osteoarthritis. Regenerative therapy with allogeneic mesenchymal stem cells (MSCs) is a promising treatment, but the safety of this procedure continues to be debated. The aim of this study is to evaluate the safety of intra-articular injections of allogeneic MSCs on healthy joints by comparing two different dosages and two different tissue sources, namely, bone marrow and umbilical cord blood, with a placebo treatment on the same individuals. We also assessed the influence of autologous versus allogeneic cells for bone marrow-derived MSC treatment. Twelve clinically sound horses were subjected to injections in their 4 fetlock joints. Each of the three fetlocks was administered a different MSC type, and the remaining fetlock was injected with phosphate-buffered saline as a control. Six horses received 10 million cells per joint, and the 6 other horses received 20 million cells per joint. Clinical and ultrasound monitoring revealed that allogeneic bone marrow-derived MSCs induced significantly more synovial effusion compared to umbilical cord blood-derived MSCs but no significant difference was noted within the synovial fluid parameters. The administration of 10 million cells in horses triggered significantly more inflammatory signs than the administration of 20 million cells. Mesenchymal stem cell injections induced mild to moderate local inflammatory signs compared to the placebo, with individual variability in the sensitivity to the same line of MSCs. Understanding the behavior of stem cells when injected alone is a step towards the safer use of new strategies in stem cell therapy, where the use of either MSC secretome or MSCs combined with biomaterials could enhance their viability and metabolic activity.

Abstract Background: Iron overload aggravates the difficulty of umbilical cord blood stem cell engraftment and reduces the survival of patients undergoing hematopoietic stem cells (HSC) transplantation. Mesenchymal stem cells (MSC) have been implicated in playing a significant role in HSC engraftment. This study aimed to determine the effect of intra-bone marrow (IBM) co-transplantation of umbilical cord blood mononuclear cells (UCB-MNC) and mesenchymal stem cells (UC-MSC) on the engraftment and hematopoietic recovery in an iron overload hematopoietic microenvironment. Methods: The iron overload model was established by dose-escalation intraperitoneal injection of iron dextran in NOD/SCID mice. Iron deposition in the bone marrow, heart, and liver was examined using H&E staining. Serum levels of ferritin and iron status in the liver were measured. The iron overload NOD/SCID mice were sublethally irradiated and divided into four groups for transplantation: (1) control group, (2) IBM MSC+ group: IBM injection of combined UCB-MNC/UC-MSC, (3) IBM group: IBM injection of only UCB-MNC, and (4) IV group: intravenous injection of UCB-MNC. Six weeks after transplantation, the human CD45 + cells in the bone marrow were analyzed by flow cytometry. The semi-quantitative analysis of vascular endothelial growth factor (VEGF-a), osteopontin (OPN), and stromal cell-derived factor-1a (SDF-1a) were examined by immunohistochemistry staining (IHC). Results: The survival rate and the percentages of human CD45 + cells in bone marrow were highest in the IBM MSC+ group with statistical significance. In addition, the levels of VEGF-a, OPN, and SDF-1a in bone marrow were all significantly higher in the IBM MSC+ group than the other groups. Conclusion: IBM co-transplantation of UC-MSC might improve the engraftment of UCB-MNC in iron overload NOD/SCID mice. The increased expression of VEGF-a, OPN, and SDF-1a in the bone marrow may be involved in improving the hematopoietic microenvironment and promoting the implantation of human umbilical cord blood stem cells in the bone marrow with iron overload.
