Expression of REDK message in bone marrow.

Total RNA from untreated (U) human bone marrow or from cells treated with stem cell factor (S), erythropoietin (E), thrombopoietin (T), granulocyte-colony stimulating factor (G), interleukin-3 (I3), or flt3 ligand (f3L) for 3 or 7 days was blotted and hybridized to the REDK cDNA probe. Hybridization to a DNA oligonucleotide probe for 28S RNA is shown to display relative loading of the RNA.
