ABSTRACT Allogeneic hematopoietic cell transplantation (allo-HCT) is an effective therapy for hematological malignancies and inherited diseases. However, acute graft-versus-host-disease (aGVHD) is a major life-threatening complication after allo-HCT and there are few therapeutic options for severe steroid-refractory aGVHD. Preliminary studies on co-transplantation of mesenchymal stem cells (MSCs) have shown an improvement in or resolution of severe aGVHD. However, the mechanism underlying this immunosuppressive effect has not been elucidated. Most of the data suggest that the immunosuppressive effect involves soluble factors such as IL-6 or TGF-beta as well as cell-cell contact dependence. MSCs interact either directly with T cells or indirectly via other immune cells such as dendritic cells and NK cells. Here we review the immunomodulatory function of MSCs in allo-HCT and their potential usefulness in the treatment or prevention of severe acute GVHD.

    ABSTRACT: Mesenchymal stromal cells (MSC) are fibroblast-like cells present in different types of tissues. Their immunomodulatory potential represents a promising method for post-transplant immunotherapy in the treatment of GVHD (graft-versus-host disease) with suboptimal response to standard immunosuppression. In this study we tested influence of 1–8 month-long cryopreservation on ability of MSC to suppress activation of non-specifically stimulated lymphocytes. We did not observe any changes in proliferation capacity of MSC after thawing. Lymphocytes metabolic activity was inhibited by 30% and number of dividing cells was three times smaller in the presence of MSC. Two activation markers were studied (CD25 and CD69) to confirm preservation of functional cell integrity. Expression of CD25 antigen on CD3+CD4+ and CD3+CD4− cells was decreased in all co-cultivated samples. Level of CD69 expression on CD3+CD4+ cells was lower in samples with added MSC (10–15% on day +2) but without reaching statistical significance. The lower expression (approximately 5%) was observed also on CD4-cells. The study confirms the preservation of immunomodulatory properties of cryopreserved and re-expanded MSC. Aliquots with cryopreserved cells can represent an optimal source for a quick preparation of MSC cell product with the possibility to apply the same cells repeatedly.

    ABSTRACT: In the present study, we compared mesenchymal stem cells (MSCs) derived from 4 different sources, human bone marrow (BM), adipose tissue (AT), umbilical cord Wharton's Jelly (WJ) and the placenta (PL), in order to determine which population of MSCs displayed the most prominent immunosuppressive effects on phytohemagglutinin-induced T cell proliferation, and which one had the highest proliferative and differentiation potential. MSC and T lymphocyte co-culture (mixed culture) was used to determine whether the MSCs inhibit T cell proliferation, as well as which population of MSCs has the strongest inhibitory ability. The expression of immune-related genes was analyzed by RT-PCR and RT-qPCR. The proliferation and differentiation potential of the MSCs were determined using standard methods. Following MSC and T cell co-culture, mitogen-induced T cell proliferation was effectively suppressed by all 4 populations of MSCs. This occurred through soluble factors rather than direct contact inhibition. Among the 4 populations of MSCs, the WJ-MSC has the strongest suppression effects. On immune related genes, WJ-MSC has the weakest expression of MHC II genes, TLR4, TLR3, JAG1, NOTCH2 and NOTCH3. To compare the proliferation potential, WJ-MSCs showed the most rapid growth rate followed by the AT-, PL- and BM-MSCs. As regards differentiation potential, the WJ-MSCs had the strongest osteogenetic ability followed by PL, AT and BM-MSC. AT-MSC has the strongest adipogenetic ability followed by the WJ-, BM- and PL-MSCs. These data indicated that the WJ-MSCs had the strongest immunomodulatory and immunosuppressive potential. In light of these observations, we suggest that WJ-MSCs are the most attractive cell population for use in immune cellular therapy when immunosuppressive action is required.

    ABSTRACT: Embryonic stem cells (ESCs) and mesenchymal stem cells (MSCs) have been studied for years as primary cell sources for regenerative biology and medicine. MSCs have been derived from cell and tissue sources, such as bone marrow (BM), and more recently from ESCs. This study investigated MSCs derived from BM, H1- and H9-ESC lines in terms of morphology, surface marker and growth factor receptor expression, proliferative capability, modulation of immune cell growth and multipotency, in order to evaluate ESC-MSCs as a cell source for potential regenerative applications. The results showed that ESC-MSCs exhibited spindle-shaped morphology similar to BM-MSCs but of various sizes, and flow cytometric immunophenotyping revealed expression of characteristic MSC surface markers on all tested cell lines except H9-derived MSCs. Differences in growth factor receptor expression were also shown between cell lines. In addition, ESC-MSCs showed greater capabilities for cell proliferation, and suppression of leukocyte growth compared to BM-MSCs. Using standard protocols, induction of ESC-MSC differentiation along the adipogenic, osteogenic, or chondrogenic lineages was less effective compared to that of BM-MSCs. By adding bone morphogenetic protein 7 (BMP7) into transforming growth factor beta 1 (TGFβ1)-supplemented induction medium, chondrogenesis of ESC-MSCs was significantly enhanced. Our findings suggest that ESC-MSCs and BM-MSCs show differences in their surface marker profiles and the capacities of proliferation, immunomodulation, and most importantly multi-lineage differentiation. Using modified chondrogenic medium with BMP7 and TGFβ1, H1-MSCs can be effectively induced as BM-MSCs for chondrogenesis.
