title: A murine cell line (2E10.4.13) produces five hemopoietic stimulators, and interleukin-2 and interleukin-3.
abstract: An interleukin-2 (IL-2)-independent murine lymphocyte clone (2E10.4.13) with the Thy1+Lyt1+2-T200+ phenotype was separated from the original IL-2-dependent natural killer (NK) cell line (PEC-1). Erythroid burst-promoting activity (BPA), erythropoietin (Ep), granulocyte/macrophage, megakaryocyte and eosinophil colony-stimulating factors (GM-, MK- and Eo-CSF), IL-2 and Interleukin-3 (IL-3) were produced when these cells were stimulated with phorbol myristate acetate (PMA). When the conditioned medium was run through ion-exchange high-performance liquid chromatography, BPA, Ep, GM-CSF, MK-CSF and Eo-CSF were eluted in the same region as IL-3. In contrast, MK-CSF, much of the GM-CSF and half of the Eo-CSF were eluted in a distinct region where no IL-3 was detected. Chemical analyses of the hemopoietic factors derived from a single T inducer clone indicated that all the hemopoietic activities were associated with IL-3 activity. Some CSF activities (GM-, MK- and Eo-CSF) also could be mediated by the distinct molecules from IL-3, evidence that heterogeneous molecules are responsible for CSF activity.
