Heterogeneous ontogeny of erythropoiesis after bone marrow ablation and allogeneic bone marrow grafting. 1983

K J Winkler, and C D Rea, and S Rahbar, and L R Hill, and K G Blume

Thirty-two patients who underwent bone marrow transplantation for hematologic malignancies were studied for hemoglobin-F as an indicator for fetal erythropoiesis. Two different patterns of response were noted. One group of patients who had an elevated HbF level prior to marrow grafting later showed a marked reactivation of HbF synthesis, whereas the other group of patients who had normal HbF levels prior to transplantation failed to exhibit such an increase. This phenomenon occurred independently of ages of marrow graft donors or recipients, the type of underlying hematologic malignancy, or remission induction therapy prior to preparation for transplantation, pretransplant hemoglobin levels, transfusion with red blood cells, red cell volume, and production of reticulocytes.

D004920 Erythropoiesis The production of red blood cells (ERYTHROCYTES). In humans, erythrocytes are produced by the YOLK SAC in the first trimester; by the liver in the second trimester; by the BONE MARROW in the third trimester and after birth. In normal individuals, the erythrocyte count in the peripheral blood remains relatively constant implying a balance between the rate of erythrocyte production and rate of destruction. Erythropoieses
