Recombinant human interleukin-11 directly promotes megakaryocytopoiesis in vitro.
We have investigated the mechanism of action of the thrombopoietic cytokine, recombinant human interleukin-11 (rhIL-11), on megakaryocytopoiesis in vitro. We have shown that rhIL-11-induced murine and human megakaryocytopoiesis are not mediated by thrombopoietin (Tpo). Murine megakaryocytes (MKs) were produced from bone marrow (BM) mononuclear cells cultured with rhIL-11, IL-3, and a combinatio...
متن کاملInterleukin-11 enhances human megakaryocytopoiesis in vitro.
We investigated the effect of recombinant human interleukin-11 (rhIL-11) on human megakaryocytopoiesis. Nonadherent and T-cell-depleted human bone marrow (BM) mononuclear cells were cultured in a serum-free agar culture system. rhIL-11 alone did not stimulate the growth of human megakaryocyte colonies. However, when rhIL-11 was combined with optimal or suboptimal doses of rhIL-3, the number and...
متن کاملRecombinant gibbon interleukin-3 acts synergistically with recombinant human G-CSF and GM-CSF in vitro.
Recombinant gibbon interleukin-3 (IL-3) is a multilineage hematopoietic colony-stimulating factor (CSF) that recently was cloned and found to be highly homologous with human IL-3. Gibbon IL-3, as well as human granulocyte-CSF (G-CSF) and human granulocyte-macrophage CSF (GM-CSF), stimulated normal human bone marrow cells to form myeloid colonies in soft agar in a sigmoidal dose-response manner....
متن کاملCloning and Expression of Recombinant Human Interleukin-7 in Chinese Hamster Ovary (CHO) Cells
Background: The critical role of interleukin-7 (IL-7) in homeostatic proliferation and T cell survival has made it a promising cytokine for the treatment of various clinical conditions, especially those associated with lymphopenia. Methods: In the present study we expressed recombinant human interleukin-7 (rhIL-7) in Chinese hamster ovary (CHO)-K1 cells. CHO-K1 cells were stably transfected ...
متن کاملRecombinant human interleukin-11 stimulates megakaryocytopoiesis and increases peripheral platelets in normal and splenectomized mice.
The effects of recombinant human interleukin-11 (rhIL-11) on in vivo mouse megakaryocytopoeisis were examined. Normal C57Bl/6 mice and splenectomized C57Bl/6 mice were treated for 7 days with 150 micrograms/kg rhIL-11 administered subcutaneously. In normal mice, peripheral platelet counts were elevated compared with vehicle-treated controls after 3 days of rhIL-11 treatment and remained elevate...
