Effect of I2 supplement on circulating immune leucocytes. Six-week-old hetero- and homozygous nude mice (with and without MDA-MB231 xenografts) were supplemented with or without 0.025% I2 (in drinking water for 6 weeks. a, The number of leukocytes in peripheral blood was determined by direct counting after dilution with Turk’s solution. b, Peripheral blood populations of leukocytes were separated and quantified by FACS (cytometric images). Differential quantification (lower panel). Data are expressed as the mean ± SD (n = 8–10 animals per group). Different letters denote statistical differences (one-way ANOVA, Tukey’s test; P < 0.05)
