Colony-forming units from WT and SK-1-KO BM cells cultured in soft agar for 14 days with growth factors and cytokines known to promote myeloid, hematopoietic, and erythroid colony growth

Cytokine/GF cocktail	WT	SK-1-KO
Nil	0 ± 0	0 ± 0
GM-CSF + G-CSF	22 ± 6	28 ± 10
IL-3 + SCF	144 ± 26	135 ± 26
IL-6 + SCF	117 ± 30	100 ± 26
IL-6 + SCF + G-CSF + EPO	123 ± 30	99 ± 23
IL-6 + SCF + IL-3 + EPO	83 ± 5	85 ± 3

Data are mean CFU plus or minus SEM from 9 mice per group.

WT indicates wild-type; and BM, bone marrow.
