Numbers of NK cells in liver (a) and spleen (b) of normal weight [Co] and obese [DIO] rats treated with NaCl or azoxymethane (AOM). Data are expressed as mean ± SEM of animals per group. , two-way-ANOVA, normal weight control groups compared to DIO groups. (c–f) Representative immunohistological detection of NK cells in liver tissue (red colored (c), (d)) and splenic tissue (blue colored; (e), (f)) in normal weight and obese rats treated with AOM (scale bar, 100 μm).
