  • Title: Fetal hemoglobin analysis of erythroid bursts in patients with chronic myelogenous leukemia (CML).
    Author: Strobel ES, Messner HA, Löhr GW, Fauser AA.
    Journal: Exp Hematol; 1983 Nov; 11(10):982-6. PubMed ID: 6198197.
    Abstract:
    Early erythroid progenitors (BFUE) form colonies of mature progeny in culture. The development of hemoglobinized red cells within multilineage colonies (CFUGEMM) and erythroid bursts is dependent upon exogenously added erythropoietin and molecules released by hemopoietic subpopulations. Mixed colonies and erythroid bursts were grown from 3 patients with Ph' chronic myelogenous leukemia (CML). It was found that some mixed hemopoietic colonies and erythroid bursts did not require exogenously added erythropoietin. An increase of the plating efficiency of BFUE could be observed when erythropoietin was added. Erythroid bursts grown without added Ep from samples of the patients with chronic myelogenous leukemia have a higher probability to contain HbF than clones grown in the presence of Ep. The data support the view of a phenotypical heterogeneity among clonal descendents of a common ancestor as previously postulated for CML.
