FIG. 5.

Colony assay of bone marrow derived from wild-type and Syk^−/− fetal liver repopulated recipients. Single-cell bone marrow suspensions were seeded into semisolid medium in the presence of IL-1α, IL-3, IL-11, Kit ligand, and erythropoietin. After 10 days, colonies were typed and counted. CFU-E, erythrocyte burst-forming unit; CFU-G, granulocyte CFU; CFU-M, macrophage CFU; CFU-GM, granulocyte-macrophage CFU; CFU-Mix, multilineage CFU (colonies consist of erythrocytes and at least two additional myeloid lineages).
