Hematological parameters of Tfr2^BMKO mice. The hematological parameters of mice were analyzed 2 and 4 months after transplantation with a WT (controls) or a Tfr2^−/− (Tfr2^BMKO) BM. Mice were fed as in legend to Figure 1 (see text for details). In the figure are graphed: (A) RBC; (B) Hb; (C) mean corpuscular volume (MCV) and (D) mean corpuscular hemoglobin (MCH). Mean values of 6 to 15 animals for genotype (controls, Tfr2^BMKO), time after BMT (2 or 4 months), and treatment (IB, ID) are graphed. Error bars indicate standard error. Asterisks refer to a statistically significant difference. *P < .05; **P < .01; ***P < .005.
