چکیده

The genetically anemic W/W° mice are characterized by the inability of their bone marrow cells to form macroscopic pluripotent hematopoietic colonies in the spleen ofirradiated recipients upon transfer (colony-forming units) . Furthermore, they almost totally lack mast cells, notably in the skin . In the present study, we have tested the effect of recombinant murine interleukin 3 (rmIIr3) on W/W° mice hematopoiesis . Transfer of W/W° bone marrow cells into lethally irradiated recipients perfused with rmIlr3 is followed by the appearance of macroscopic spleen colonies. Moreover, perfusion of rmIL3 in W/W° mice: (a) restores almost normal total numbers ofhematopoietic precursors (colony-forming cells), but without modification of anemia; and (b) leads to the appearance of a normal number of mastocytes in the skin .

Interleukin 3 perfusion in W/Wv mice allows the development of macroscopic hematopoietic spleen colonies and restores cutaneous mast cell number

The genetically anemic W/Wv mice are characterized by the inability of their bone marrow cells to form macroscopic pluripotent hematopoietic colonies in the spleen of irradiated recipients upon transfer (colony-forming units). Furthermore, they almost totally lack mast cells, notably in the skin. In the present study, we have tested the effect of recombinant murine interleukin 3 (rmIL-3) on W/W...

Effect of daunorubicin drug with and without cimetidine on the nucleated cells of bone marrow of balb/c mouse

Introduction: Hematopoiesis is an on going process mammalian marrow system. A few cells from the nucleated cells of bone marrow are hematopoietic cells which include primary stem cells, precursor cells and progenitor cells. Primary stem cells and progenitor cells are able to produce colonies in culture medium (CFU-C) and irradiated mouse spleen (CFU-S). A hematopoietic cell is alive and act...

Declining sensitivity to interleukin 3 of murine multipotential hemopoietic progenitors during their development. Application to a culture system that favors blast cell colony formation.

When spleen cells of 5-fluorouracil (5-FU)-treated mice were cultured in the presence of interleukin 3 (IL-3), most colonies revealed IL-3 concentration-dependent colony formation except for mast cell colonies and blast cell colonies. While most colonies were smaller in lower concentrations of IL-3, the size of the blast cell colonies were similar between high and low IL-3 groups. These data su...

Enhancement of murine blast cell colony formation in culture by recombinant rat stem cell factor, ligand for c-kit.

Mice with W mutations characterized by hypopigmentation, sterility, anemia, and mast cell deficiency have abnormalities in c-kit, a receptor with tyrosine kinase activity. Recently, the ligand for c-kit was cloned by investigators in several laboratories. Zsebo et al identified and cloned a gene for a cytokine termed stem cell factor (SCF) in the medium conditioned by buffalo rat liver cells, a...

Human granulocyte colony-stimulating factor (G-CSF) stimulates the in vitro and in vivo development but not commitment of primitive multipotential progenitors from transgenic mice expressing the human G-CSF receptor.

Granulocyte colony-stimulating factor (G-CSF) stimulates the proliferation and restricted differentiation of hematopoietic progenitors into neutrophils. To clarify the effects of G-CSF on hematopoietic progenitors, we generated transgenic (Tg) mice that had ubiquitous expression of the human G-CSF receptor (hG-CSFR). In clonal cultures of bone marrow and spleen cells obtained from these mice, h...
