Abstract (original English)

To characterize different tissue MSCs as sources of cell immunomodulatory therapy. Examined the effects of IFN-γ on WJ-MSC and their immunomodulatory function characteristics. We compared human fetal bone marrow (F-BM), adipose tissue (AT), and Warton's Jelly-derived MSCs (WJ-MSCs) for surface antigen expression, differentiation ability, proliferation capacity, clonality, tolerance for aging, gene expression, and whether IFN-γ affected WJ-MSC gene expression, as determined by real time quantitative PCR. Fifteen geneswere examined. We further assess WJ-MSCs-mediated immunomodulatory on peripheral blood mononuclear, stimulated by PHA, IL-2 and CD3Ab after 5 days of co-cultured in a 5:1 ratio (PBMC:MSCs). Examined the effect of WJ-MSCs on the Th1, Th2, Th17 cytokines production and Treg augument. MSCs from different tissues have similar levels of cell surface antigen expression and differentiation ability, while F-BM-MSCs and WJ-MSC had higher rates of cell proliferation and clonality than AD-MSCs. All 15 genes were expressed at similar levels in WJ-MSCs and AD-MSCs (P > 0.05). 9 genes were upregulated in WJ-MSCFor F-MSC, including IL-6, CXCL9, CXCL10, CXCL11, ICAM-1, IDO1, HLA-G5, SDF1A, and NOTCH were down expression, but VCAM-1 was lower expressionin WJ-MSCS. After IFN-γ treatment, 7 genes were upregulated in WJ-MSC, including chemokine ligands CXCL9, CXCL10 and CXCL11, and the
