| abstractText | Erythroid myeloid lymphoid (EML) cells are an established multipotent hematopoietic precursor cell line that can be maintained in medium including stem cell factor (SCF). EML cultures contain a heterogeneous mixture of cells, including a lineage-negative, CD34+ subset of cells that propagate rapidly in SCF and can clonally regenerate the mixed population. A second major subset of EML cells consists of lineage-negative. CD34- cells that can be propagated in IL-3 but grow slowly, if at all, in SCF, although they express the SCF receptor (c-kit). The response of these cells to IL-3 is stimulated synergistically by SCF, and we present evidence that both the synergy and the inhibition of c-kit responses may be mediated by direct interaction with IL-3 receptor. Further, the relative level of tyrosine phosphorylation of various substrates by either cytokine alone differs from that produced by the combination of the two cytokines, suggesting that cell signaling by the combination of the two cytokines differs from that produced by either alone. |
