  • Title: Endogenous BFU-E in peripheral blood in diagnosis of polycythemia vera.
    Author: Biljanović-Paunović L, Ruvidić R, Pavlović-Kentera V.
    Journal: Eur J Haematol; 1990 Nov; 45(5):262-6. PubMed ID: 2261952.
    Abstract:
    Erythroid progenitors (CFU-E and BFU-E) growth in vitro from bone marrow and peripheral blood of patients with polycythemia vera (PV) was studied using a methylcellulose culture technique. The aim of the study was to find out whether the in vitro colony formation of peripheral blood could be used in the differential diagnosis of PV. In all 25 patients studied, endogenous colonies were found in the bone marrow and peripheral blood. The parallel study of both bone marrow and peripheral blood erythroid progenitors indicates that the presence of endogenous BFU-E in peripheral blood is a dependable test for PV. The results presented here showed that the abnormalities in PV erythroid progenitors are expressed at the level of both CFU-E and BFU-E, suggesting multiple changes in the erythroid progenitors. Our finding indicate that peripheral blood BFU-E differ from bone marrow BFU-E with regard to their dependence for further differentiation on BPA, the activity present in PHA-LCM.
