Figure 1 Proliferation of ECV304 inhibited by the supernant of BHK-21 transfected with pSecES and proliferation of spleen lymphocytes stimulated by the supernant of BHK-21 trans-fected with pmIL-12. Each bar represents A value of ECV304 or spleen lymphocytes, and mean ± SD for 5 wells. ^aP < 0.05 vs control, ^bP < 0.01 vs control.
