  • Title: Reactions of the erythroid hemopoietic stem and their mechanisms during blood loss.
    Author: Zyuzkov GN, Abramova EV, Dygai AM, Goldberg ED.
    Journal: Bull Exp Biol Med; 2005 Jan; 139(1):27-31. PubMed ID: 16142268.
    Abstract:
    We studied changes in the erythroid hemopoietic stem during blood loss of different severity. Stimulation of erythropoiesis during the posthemorrhagic period was related to functional activation of erythroid precursors, which resulted from changes in feeder capacity of cells from the hemopoiesis-inducing microenvironment and erythropoietic activity of the plasma. The development of encephalopathy under conditions of massive blood loss was accompanied by a reduction of erythroid hyperplasia due to a decrease in the number of proliferating erythroid precursor cells, despite high secretory activity of adherent myelokaryocytes, rise in erythropoietic activity of the plasma, increased formation of erythroid hemopoietic islets, and accelerated maturation of hemopoietic cells.
