  • Title: Intercellular contacts between erythroid precursors in the bone marrow in dyserythropoiesis.
    Author: Frisch B, Lewis SM, Swan M.
    Journal: Br J Haematol; 1976 Aug; 33(4):469-75. PubMed ID: 1009019.
    Abstract:
    The ultrastructure of the cellular interfaces between erythroid precursors has been studied in both congenital and acquired dyserythropoiesis. The types of cell-to-cell contacts found included highly convoluated interdigitating septate-like junctions as well as apparent confluence of the cellular membranes of adjacent erythroid cells. Such findings are not characteristic of the intercellular relationships found in the normal erythroblastic islands. The erythroid plasma membrane modifications are possibly related to the changes in the plasma membranes of erythroid cells known to occur in dyserythropoiesis and their presence may well contribute to the ineffective erythropoiesis with intramedullary cell destruction which characterizes many dyserythropoietic states.
