The effects of bone marrow-conditioned medium obtained from colony-stimulating factor-producing tumor-bearing nude mice (G-BM-CM) on mouse and human granulocyte-macrophage colony formation and mouse erythroid colony and burst formation were studied. Addition of G-BM-CM into the mouse granulocyte-macrophage colony-forming system containing colony-stimulating activity more strongly inhibited gran...

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...

Objectives Use of point-of-care testing is increasing, however many haematology analysers can only determine granulocyte count without further differentiation into neutrophils, eosinophils and basophils. Since the diagnosis of life-threatening neutropenia in cancer patients requires a distinct neutrophil count, this study aimed to determine the comparative performance between the neutrophil and...

Recent studies have demonstrated that systemic Corynebacterium parvum increases serum granulocyte-macrophage colony-stimulating factor and stimulates the proliferation of granulocyte-macrophage progenitor cells. It was hypothesized that more rapid cycling of granulocyte-macrophage progenitor cells would render the cells more sensitive to a cell cycle-specific chemotherapeutic agent. The colony-...

BACKGROUND Following the release of the initial presentation of filgrastim (granulocyte colony-stimulating factor), several biosimilars have been developed worldwide. OBJECTIVE To study the efficacy of a Mexican biosimilar granulocyte colony-stimulating factor in a single transplant center. METHODS In a group of 19 consecutive patients with multiple sclerosis given autografts, we employed g...

BACKGROUND We report on the efficacy and side effects of granulocyte collection, which is comparatively infrequently performed in Germany. METHODS Data from 378 healthy donors who underwent 914 granulocyte collections between 1999 and 2007 were retrospectively analyzed. Donors received G-CSF (lenograstim) at a median dose of 5.58 (3.25-7.36) μg/kg body weight with (n = 243) or without (n = 57...

bakground: granulocyte colony-stimulating factor (g-csf) is a cytokine that stimulates hematopoiesis and induces proliferation and differentiation of granulocyte progenitor cells as well as production of bone marrow neutrophilic granulocyte colonies.  nowadays, human recombinant g-csf(hr g-csf) is used for the treatment of chemotherapy- and radiotherapy-induced neutropenia, and also in patients...
