Lin− cells were stained, gated, and sorted as shown in Fig 1. Bone marrow frequencies of Lin−c-kit+, Lin− c-kitLo, and Lin− c-kit− cells reflect means from three or four independent experiments with marrow pooled from 9 or 10 mice. Frequencies of TdT+ populations within bone marrow were calculated from percentages of TdT+ cells within the indicated subsets. Fold enrichment of Lin−TdT+ cells within each subset is relative to the frequency among bone marrow mononuclear cells (0.304%).
