A mouse spleen stromal cell line, MSS62, can create an in vitro erythropoietic microenvironment in which development of erythropoietin-responsive progentor cells is stimulated by cell-cell contact via stem cell factor (SCF)/c-Kit and vascular cell adhesion molecule-1 (VCAM-1)/very late activation antigen-4 (VLA-4) interactions between stromal and erythroid cells. To find out the effect of src on the erythropoietic microenvironment, MSS62 cells were transfected with v-src oncogene, and its effect on erythropoietic stimulatory activity was measured. Transfectants with high v-Src activity showed reduction in erythropoietic stimulatory activity. A decrease in cell-surface VCAM-1 and SCF mRNA was accompanied by high v-Src activity. These results suggest that v-Src interferes with the erythropoietic stimulatory activity of the stromal cells through repression of VCAM-1 and SCF.
