FL stimulates/costimulates proliferation of myeloid progenitor cells from marrows of Stat5b+/+ and Stat5b−/− mice to the same extent. Results are shown as the average percentage of control of cells incubated with 50 ng/ml SLF plus 10 ng/ml GM-CSF for a total of two experiments each. The control colony numbers upon which the percentage of control are based were 66 ± 2 and 93 ± 1 for Stat5b−/− cells, and 93 ± 2 and 74 ± 3 for Stat5b+/+ cells.
