Representative flow cytometry dot plots of cells from bi-5 mice and littermate controls.

(A) Thymus, (B) spleen, and (C) bone marrow. Scattergram plot (D) of the percentage of normal cell number for spleen (Spl) and thymus (Thy). Each data point on the plot represents the percentage of total thymocyte number that a bi-5 mouse had to a littermate control harvested on the same day. (E) Splenic NK cell number versus mouse age. NK cells were scored by NK1.1⁺/CD3⁻staining.
