hAD-MSCs induce CD4⁺ T cells apoptosis via FAS/FASL pathway A Representative flow cytometry cytograms of CD4⁺ T cells apoptosis after 5 days cocultured with hMSCs. B Flow cytometric quantitation of CD4⁺ T cells apoptosis cocultured with hMSCs in the absence or presence of anti-FASL antibody (1 μg/ml). Apoptosis rate was calculated by the sum of early apoptosis and late apoptosis. The bars represent mean ± SD of triplicate biological replicates. *P < 0.05; ns not significant; P values were calculated by unpaired t-test
