Fig 9. Expression of IFN-γ, IL-4 and GAL-7 in the spleen of SF and WL.

Lower expression levels of IFN-γ (a) and IL-4 (b) were detected in SF at 10 and 6 weeks of age, respectively, but higher expression levels were detected in SF at 23 weeks of age. High expression level of GAL-7 was detected in SF before 6 weeks of age, but low expression levels were detected at 10 and 23 weeks of age. (c). *P < 0.05, **P < 0.01.
