Fig. 5. The jejunal cell apoptosis by flow cytometry assay. (a–e) The representative scattergram of apoptotic jejunal cells obtained by flow cytometry assay in the control group (a), Se group (b), AFB₁ group (c) and AFB₁ + Se group (d) at 21 days of age; (e) apoptotic rates by flow cytometry assay. Note: Data are presented with the means ± standard deviation (n = 6). Letters A, B, C and D represent the significant difference (p < 0.01) between the group and control group, Se group, AFB₁ group, and AFB₁ + Se group, respectively. Letters a, b, c, and d represent the difference (p < 0.05) between the group and control group, Se group, AFB₁ group, and AFB₁ + Se group, respectively.
