Fig. 5. Effect of MSC on apoptosis of allogeneic lymphocytes following co-culture at ratios of 1 : 1 and 1 : 5 for 3 days. The test was conducted by Annexin-V and PI double staining and analyzed by flow cytometry. Apoptosis of MSC gated on size (A–C) and apoptosis of lymphocytes gated on size (D–F) were analyzed following MSC and activated lymphocytes were cultured alone (A and D) or cocultured at a ratio of 1 : 1 (B and E) and 1 : 5 (C and F).
