Purified preparations of recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte CSF (G-CSF), and interleukin 3 (IL-3 or multi-CSF) alone and in combination, have been compared for their stimulatory effects on human granulocyte-macrophage colony forming cells (GM-CFC). In cultures of unseparated normal human bone marrow, the combinations of G-CSF plus IL-3 and G...

Supernatants of COS-1 cells transfected with gibbon cDNA encoding interleukin 3 (IL-3) with homology to sequences for human IL-3 were tested for ability to promote growth of various human hemopoietic progenitors. The effect of these supernatants as a source of recombinant IL-3 was compared to that of recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) and granulocyte col...

We have previously reported on stimulation of clonal growth of cell lines from human solid tumors by recombinant human interleukin 3, recombinant human granulocyte-macrophage colony-stimulating factor, and recombinant human granulocyte colony-stimulating factor (W. E. Berdel et al.. Blood, 73: 80-83, 1989; Exp. Hematol., 16: 510, 1988). Within an extensive screening program of hematopoietic gro...

The endometrium is an important part of the uterus. human a complex and dynamic tissue that goes through phases growth regression during any menstrual cycle. A thin might be relevant to lower rate implantation as well higher miscarriage. Several treatments have been developed for endometrium, such granulocyte colony-stimulating factor, stem cell therapy, acupuncture physical among others. These...

Growth and differentiation signals mediated by different regions in the cytoplasmic domain of granulocyte-stimulating factor receptor. Touw IP: Distinct cytoplasmic regions of the human granulocyte colony-stimulating factor receptor involved in induction of proliferation and maturation.: The clonal proliferation of normal mouse hematopoietic cells: Enhancement and suppression by colony-stimulat...

Human recombinant granulocyte-macrophage colony-stimulating factor (hrGM-CSF) stimulated granulocyte-macrophage (GM) colony formation from human marrow mononuclear cells (MMCs) in a dose-dependent manner in methylcellulose culture. When phagocytes were depleted from MMCs, GM colony formation from the phagocyte-depleted (PD) MMCs by hrGM-CSF markedly decreased. Experiments in which PD-MMCs were ...

Normal hematopoiesis is a well-regulated process in which the generation of mature blood elements occurs from a primitive pluripotent stem cell in an ordered sequence of maturation and proliferation. Regulation occurs at the level of the structured microenvironment (stroma), via cell-cell interactions and by way of the generation of specific hormones and cytokines: erythropoietin, interleukin 3...

Current treatments for Crohn's disease are aimed at suppressing excessive immune activation in the bowel walls. However, alternative strategies can be drawn. These involve the augmentation of the innate immune response, in the hypothesis that patients affected with Crohn's disease are characterized by a relative immunodeficiency, with failure of the defensive barrier to luminal microbes and mic...

Highly purified murine granulocyte-macrophage progenitor cells (CFU-GM) were used as target cells to assess the possible direct effects of purified preparations of recombinant murine 7-intcrferon, prostaglandin E, recombinant human heavy chain (acidic) ferritin, and recombinant human tumor necrosis factor a (TNF-a) on progenitor cells in vitro. Target CFU-GM, with cloning efficiencies of up to ...
