IFN-γ stimulation methods. P3 untreated [−/− transforming growth factor-β2 (TGF-β2)], pretreated (+/− TGF-β2), and continuously treated (+/+ TGF-β2) mesenchymal stem cells (MSCs) were stimulated with 1 ng/ml equine IFN-γ over a 72-h period. Untreated and pretreated MSCs not stimulated with IFN-γ were used as controls. Major histocompatibility complex (MHC) I and MHC II expression was measured via FACS following stimulation. Baseline MHC expression was obtained by freezing cells from each treatment group just prior to IFN-γ stimulation.
