| Abstract: | Erythroid progenitors were assayed in 20 chronic hemodialysis patients before and after administration of recombinant human erythropoietin (rhEpo) using a methylcellulose culture method. Hemoglobin concentrations, hematocrit values and the proportion of marrow erythroblasts increased significantly during rhEpo treatment. The numbers of erythroid progenitors (CFU-e and BFU-e) in the patients' marrow also increased following rhEpo administration. Our data suggest that rhEpo is an effective drug for treating anemia caused by chronic renal failure and the administration of rhEpo results in an increase in the numbers of erythroid progenitors. |
