CD4⁺CD117⁺ cells from the thymus and spleen suppress T cells in vitro. T-cell proliferation was measured by flow cytometry to measure fluorescence intensity. a CD4⁺CD117⁺ cells sorted from the thymus. b CD4⁺CD117⁺ cells sorted from the spleen. Thymocyte data (c) and spleen data (d) pooled from three independent experiments. Data are mean percent of the total ± SD from three independent experiments. **p < 0.01, ***p < 0.001
