We have identified and characterized the lymphohematopoietic progenitors in the bone marrow of normal mice using a single-step methylcellulose culture assay. Lineage-negative Ly-6A/E (Sca-1)+ progenitors isolated from normal mice were plated in methylcellulose culture containing steel factor (SF), interleukin-7 (IL-7), erythropoietin (Ep), and IL-11. After(More)
We recently reported that interleukin-3 (IL-3) inhibits B lymphoid lineage expression in methylcellulose culture in a dose-dependent manner. We subsequently used flow cytometric analysis of individual colonies in timed exposure to IL-3 to define more precisely the negative regulatory role of IL-3 in early B lymphopoiesis. When lymphohematopoietic(More)
