Two-step differentiation of AML-193 leukemic line: terminal maturation is induced by positive interaction of retinoic acid with granulocyte colony-stimulating factor (CSF) and vitamin D3 with monocyte CSF.
The human AML-193 cell line requires exogenous granulocyte-monocyte colony-stimulating factor (GM-CSF) or interleukin-3 (IL-3) for growth in liquid or semisolid medium. However, these CSFs do not stimulate the differentiation of the cell line. We show that addition of all-trans retinoic acid (RA) or 1,25 dihydroxyvitamin D3 (D3) induces AML-193 cells to differentiate into the granulocytic or mo...
متن کاملRecombinant human macrophage colony-stimulating factor (M-CSF) requires subliminal concentrations of granulocyte/macrophage (GM)-CSF for optimal stimulation of human macrophage colony formation in vitro
Human macrophage colony-stimulating factor (M-CSF or CSF-1), either in purified or in recombinant form, is able to generate macrophagic colonies in a murine bone marrow colony assay, but only stimulates small macrophagic colonies of 40-50 cells in a human bone marrow colony assay. We report here that recombinant human granulocytic/macrophage colony stimulating factor (rhGM-CSF) at concentration...
متن کاملStimulation by human placental conditioned medium of hemopoietic colony formation by human marrow cells.
Medium conditioned by human placental tissue was found to stimulate granulocytic and monocytic colony formation by human marrow cells in semisolid agar cultures. The colony-stimulating activity of unfractionated conditioned medium was equivalent to the activity of standard peripheral blood underlayers. Placentas were a reliable source of active material, and one placenta provided enough materia...
متن کاملProliferative but not nonproliferative responses to granulocyte colony-stimulating factor are associated with rapid activation of the p21ras/MAP kinase signalling pathway.
Granulocyte colony-stimulating factor (G-CSF) can elicit responses that include proliferation, granulocytic differentiation, and activation of cellular functions in target cells. The biochemical pathways responsible for transduction of these signals from the G-CSF receptor (G-CSFR) have not been defined. In this report, we show that, in murine (NFS-60) and human (OCI-AML 1) myeloid leukemia cel...
متن کاملThe nature and action of granulocyte-macrophage colony stimulating factors.
Granulocyte-macrophage colony stimulating factor (GM-CSF) stimulates the in vitro proliferation and differentiation of granulocytic and macrophage cells. This regulator is now known to act at other levels of hemopoietic regulation. The heterogeneity of GM-CSFs is not only related to the tissue of origin and the in vitro production method, but also to functional subclasses of the molecule that h...
