Human Progenitors in the BM of NOD/SCID Mice Transplanted With CD34⁺CD38^−/low Cells That Were Cultured Ex Vivo for 6 Days

Cytokine Combination	Total Colonies^*	Primitive Colonies^†
SCF + FL	5 ± 1	0 ± 0
SCF + FL + IL6RIL6 chimera	80 ± 10	11 ± 4

Cytokine Combination	Total Colonies^*	Primitive Colonies^†
SCF + FL	5 ± 1	0 ± 0
SCF + FL + IL6RIL6 chimera	80 ± 10	11 ± 4

Data shown represent mean ± SE from 3 independent experiments (P = .01, 2 tails, paired t-test).

With SCF + FL, only macrophage colonies were found. When IL6RIL6 was added, mixed GEMM, BFU-E, and blast colonies were seen.
