Acquisition of IL-7R corresponds with rapid B-lineage differentiation in culture.
Cultures were initiated with Lin− c-kitLoFlk-2/Flt-3+ IL-7Rα+ (♦) or Lin− c-kitLo Flk-2/Flt-3+IL-7RαLo/− (■) cells and evaluated at the indicated intervals. Numbers of CD19+ lymphocytes recovered per input precursor are shown from one of 3 independent experiments that gave very similar results.
