  • Title: Changes in granulocytic hemopoietic stem and their mechanisms during hypoxia of different genesis.
    Author: Zyuz'kov GN, Dygai AM, Gol'dberg ED.
    Journal: Bull Exp Biol Med; 2005 Mar; 139(3):279-82. PubMed ID: 16027830.
    Abstract:
    We studied reactions of the granulocytic hemopoietic stem during hypoxia of different genesis and severity. Stimulation of granulocytopoiesis was determined by an increase in functional activity of granulomonocytic precursors due to changes in feeder capacity of cells in the hemopoiesis-inducing microenvironment and colony-stimulating activity of the plasma. The development of encephalopathy caused by oxygen deficiency was accompanied by a decrease in the number of bone marrow granulomonocytic precursors due to reduction of proliferative activity (despite the increase in secretory activity of microenvironmental cells and increase in plasma colony-stimulating activity). Severe hypoxia accelerated maturation of hemopoietic cells and produced neutrophilic leukocytosis.
