the present study aimed at investigating the beneficial effects of co-administering granulocyte colony–stimulating factor (g-csf) and stem cell factor (scf) in a model of chronic liver injury induced by thioacetamide (taa). biochemical and histopathology- cal examinations were performed on serum and liver specimens. at the end of the treatment period, the rats were anesthetized with ether, seru...

A panel of monoclonal antibodies was raised against the low-affinity human granulocyte-macrophage colony-stimulating factor (hGM-CSF) receptor a-chain expressed as recombinant protein on murine FDC-P1 cells. All the selected antibodies were of the lgG2A isotype and bound to protein A. They each recognized both native and recombinant receptors by indirect surface immunofluorescence and by immuno...

We have used a serum-free culture system for enriched human hemopoietic progenitors to analyze the developmental stages and lineage specificities of the human hemopoietic colony-stimulating factors. None of the individual factors alone efficiently supported hemopoietic colony formation. Neither interleukin 3 nor granulocyte/macrophage-colony-stimulating factor alone or in combination effectivel...

Hematopoietic stem/progenitor cells (HSPCs) which give rise to different blood cell types are present within the bone marrow microenvironment, especially in flat bones such as skull, vertebrae, pelvis and chest. Interacting factors such as stromal derived factor-1/CXCR4, very late antigen-4/vascular cell adhesion molecule-1, Lymphocyte function-associated antigen-1/ intercellular adhesion molec...

Activation of specific cytokine receptors promotes survival and proliferation of hematopoietic progenitor cells but their role in the control of differentiation is unclear. To address this issue, the effects of human interleukin-3 (hIL-3) and human granulocyte-macrophage colony-stimulating factor (hGMCSF) on hematopoietic development were investigated in hematopoietic progenitor cells. Murine m...
