Hematopoietic defects of SHIP1^el20/el20 mice. Representative dot plots of (A) bone marrow B220^loCD25⁺ pre-B cells, (B) bone marrow Mac-1⁺Gr-1⁺ myeloid cells, and (C) thymic T-cell subsets from 5-week-old mice. The mean proportion for each subset was gated on live hematopoietic cells and calculated from at least 3 mice of each genotype.
