Characteristics of Human Turbinate-Derived Mesenchymal Stem Cells Are Not Affected by Allergic Condition of Donor.

ABSTRACT: The characteristics of mesenchymal stem cells (MSCs) derived from human turbinates (hTMSCs) have not been investigated in allergic rhinitis. We evaluated the influence of allergic state of the donor on the characteristics, proliferation, and differentiation potential of hTMSCs, compared with hTMSCs derived from non-allergic patients. hTMSCs were isolated from five non-allergic and five allergic patients. The expression of toll-like receptors (TLRs) in hTMSCs was measured by FACS, and cell proliferation was measured using a cell counting kit. Cytokine secretion was analyzed using multiplex immunoassays. The osteogenic, chondrogenic, and adipogenic differentiation potentials of hTMSCs were evaluated by histology and gene expression analysis. In allergic patients, FACS analysis showed that TLR3 and TLR4 were more highly expressed on the surface of hTMSCs than TLR2 and TLR5. The proliferation of hTMSCs was not influenced by the presence of TLR priming. The expression of IL-6, IL-8, IL-12, IP-10, and RANTES was upregulated after the TLR4 priming. The differentiation potential of hTMSCs was not influenced by TLR priming. These characteristics of hTMSCs were similar to those of hTMSCs from non-allergic patients. We conclude that the allergic condition of the donor does not influence TLR expression, proliferation, or immunomodulatory potential of hTMSCs.

Project description:Mesenchymal stem cell (MSC) has great potential for both regenerative medicine and immunotherapy due to its multipotency and immunomodulatory property. The derivation of MSCs from human tissues involves an invasive procedure and the obtained MSCs often suffer from inconsistent quality. To overcome these issues, the approaches of deriving a highly potent and replenishable population of MSCs from human embryonic stem cells (hESCs) were established. However, few studies compared the immunological characteristics of MSCs derived from hESCs with tissue-derived MSCs or demonstrated differences and the underlying mechanisms. Here, we differentiated H9 hESCs into MSC-like cells (H9-MSCs) through an embryoid body outgrowth method and compared the immunological characteristics of H9-MSCs with bone marrow-derived MSCs (BMSCs). Both sources of derived cells exhibited typical MSC morphologies and surface marker expressions, as well as multipotency to differentiate into osteogenic and adipogenic lineages. A immunological characterization study showed that H9-MSCs and BMSCs had similar immunoprivileged properties without triggering allogeneic lymphocyte proliferation as well as equivalent immunosuppressive effects on T-cell proliferation induced by either cellular or mitogenic stimuli. Flow cytometry analysis revealed a lower expression of human major histocompatability complex class II molecule human lymphocyte antigen (HLA)-DR and a higher expression of coinhibitory molecule B7-H1 in H9-MSCs than in BMSCs. Interferon gamma (IFN-γ) is a proinflammatory cytokine that can induce the expression of HLA class II molecules in many cell types. Our results showed that pretreatment of H9-MSCs and BMSCs with IFN-γ did not change their immunogenicity and immunosuppressive abilities, but increased the difference between H9-MSCs and BMSCs for their expression of HLA-DR. Further detection of expression of molecules involved in IFN-γ signaling pathways suggested that the lower expression of HLA-DR in H9-MSCs could be partially attributed to the lower expression and the less nuclear translocation of its transcriptional factor CIITA. The present study provides evidence that the hESC-derived MSCs share similar immunogenicity and immunosuppressive abilities with BMSCs, but differ in the expression profile of immunological markers and the responsiveness to certain inflammatory cytokines, which suggests that H9-MSCs could be a safe and efficient candidate for MSC treatment in patients with inflammatory disorders.
