Mesenchymal stem cells (MSCs) represent a promising means to promote tissue regeneration. However, the heterogeneity of MSCs impedes their use for regenerative medicine. Further investigation of this phenotype is required to develop cell therapies with improved clinical efficacy. Here, a small-sized population of human umbilical cord blood-derived MSCs (UCB-MSCs) was isolated using a filter and centrifuge system to analyze its stem cell characteristics. Consequently, this population showed higher cell growth and lower senescence. Additionally, it exhibited diverse stem cell properties including differentiation, stemness, and adhesion, as compared to those of the population before isolation. Using cell surface protein array or sorting analysis, both EGFR and CD49f were identified as markers associated with the small-sized population. Accordingly, suppression of these surface proteins abolished the superior characteristics of this population. Moreover, compared to that with large or nonisolated populations, the small-sized population showed greater therapeutic efficacy by promoting the engraftment potential of infused cells and reducing lung damage in an emphysema mouse model. Therefore, the isolation of this small-sized population of UCB-MSCs could be a simple and effective way to enhance the efficacy of cell therapy.

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.

Introduction: Establishing a reproducible adult stem cell culture system, such as mesenchymal stem cells (MSCs), is critical for elucidating the function of molecular markers associated with these cells' undifferentiated state. In this study, we describe some important parameters to be considered for a successful isolation, culture, and characterization of MSCs from human umbilical cord blood (hUCB). Methods: Five hUCB samples were collected from healthy female subjects who were free from infectious diseases and genetic disorders. Mononuclear cells (MNCs) were counted, and viability was determined using MTT assay. MNCs were cultured in DMEM supplemented with 10% fetal bovine serum and enriched through culture and characterized using morphometric, and molecular analysis. Results: The minimum number of cells was 12.5 million and highest number of cells was 20.6 million from all ve samples. In initial culture of MSCs from hUCB, various morphologic phenotypes were seen, although the cells eventually developed a homogeneous broblast-like shape at day 14 showing >80% conuency. Spindle-shaped clonogenic MSCs expressed a high level of CD90, CD105, and CD73, while negative expression of CD34. Our study provided evidence of expansion of enriched MSCs in culture from day 1 to day 21 as supported by data of CD90, CD105 and CD73 expression levels in a time-dependent manner. Conclusion: Our results suggest that the expanded hUCB harbor an enriched source of MSCs that express pluripotent stem cell markers and lack hematopoietic markers after culture and forms the basis for using hUCB as eminent source of MSCs, which can be used for different therapeutic applications.
