(C) Comparison of the femoral bone marrow, thymus, and spleen cellularities of Desrt +/+ andDesrt −/−mice at 3-wk of age (solid bars) and at 6 wk (open bars). The cellularities of Desrt −/−animals were compared with the cellularity of age matchedDesrt +/+ animals and significant differences are indicated (*, p <0.05; **, p <0.01; ***,p <0.001).
