IL-7Rα-expressing cells in the donor-derived cells from bone marrow of recipients of transplanted WT SCL- and DN SCL-transduced HSCs. (A) Results of representative FACS analysis 10 weeks after transplantation. Numbers in quadrants represent the ratio of cells in the respective quadrants. (B) Mean of IL-7α-expressing cells in GFP⁺-gated or nongated subpopulations in lineage-depleted bone marrow cells from recipients. Data show the mean ± SD of 2 to 4 mice from 2 independent experiments.
