Stem cells from human exfoliated deciduous teeth ameliorate concanavalin A-induced autoimmune hepatitis by protecting hepatocytes from apoptosis

Figure 2 Pretreatment with stem cells from human exfoliated deciduous teeth reduces inflammation in concanavalin A-induced hepatitis. A: CD3⁺ and CD4⁺ T cell expression in liver tissues; B: Quantitative analysis of the number of CD3⁺ T cells; C: Quantitative analysis of the number of CD4⁺ T cells; D: Tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ) expression in liver tissues; E: Quantitative analysis of the number of TNF-α⁺ cells; F: Quantitative analysis of the number of IFN-γ⁺ cells; G: Serum TNF-α levels; H: Serum IFN-γ levels. Arrows indicate positive cells in the liver section; I: Th1 cells detected by flow cytometry; J: Quantitative analysis of the percentage of CD4⁺ IFN-γ⁺ T cells; Scale bars = 100 μm. ^aP < 0.05; ^bP < 0.01; n ≥ 3.
