Fig. 4.
Group responses of recipient Fischer rat LNCs to control stimuli. Groups are described in Figure 2 and the Figure 2 legend. LNCs (3×105 cells/well) obtained from individual rats at 4 or 8 weeks were cultured in medium alone (A) or with syngeneic Fischer strain spleen cells (2×105 cells/well, B). The cultures were harvested at 3 or 7 days as indicated. Proliferative responses are designated as CPM because background responses were not subtracted. The mean group response ± standard error of the mean is shown. Significant differences from the No Trt background response are denoted with an asterisk (p < 0.05).
