Enhanced Immune-suppression Activities of CD317⁺ MSCs. A Representative figures of spleen of IBD mice transplanted with CD317⁺ MSCs, CD317⁻ MSCs, or negative control PBS. B Spleen weight of IBD mice transplanted with CD317⁺ MSCs, CD317⁻ MSCs, or negative control PBS (n = 8). C Representative figures of CD45 staining of colon tissues after 10 days post DSS stimulation. D Serum levels of IL-6, IL-1β, TNF-α, IFN-γ, IL-10, TGF-β, TSG6, and IL-1RA were determined via ELISA (n = 8). E mRNA levels of IL-6, IL-1β, TNF-α, IFN-γ, IL-10, TGF-β, TSG6, and IL-1RA in colon tissues were determined via qPCR (n = 8). *Indicates P < 0.05
