Inhibition of CD4 and CD8 T cell proliferation and intracellular IFN-γ production. MSC and αCD3CD28-stimulated and CSFE-labelled PBMCs were co-cultured at different ratios for 7 days. Thereafter proliferation of a CD4 and b CD8 T cells was measured utilizing CFSE dilution with FACS. Proliferation is expressed as the percentage of proliferating cells relative to the positive control in the absence of ucMSC. c IFN-γ production by CD4 and d CD8 T cells was measured using FACS and an intracellular labelling of IFN-γ. The IFN-γ-containing CD4 and CD8 T cells are represented as a percentage from the CD4 or CD8 T cell population. Results are shown as means ± SEM (n = 5). *Indicates significant difference (p < 0.05). IFN-γ interferon gamma, MC multiple cytokine cocktail, PBMC peripheral blood mononuclear cells, RA retinoic acid, Starv starvation, serum deprivation, TGFβ transforming growth factor beta, ucMSC umbilical cord-derived mesenchymal stromal cells, VitB 6 vitamin B6, pyridoxal hydrochloride
