Abstract |
Flow cytometric reticulocyte quantification with thiazole orange (TO) was used to study erythropoiesis in 20 patients following autologous bone marrow transplantation for the treatment of acute myelogenous leukemia. Flow cytometric reticulocyte analysis provided not only the reticulocyte percentage and absolute reticulocyte count but a quantitative reticulocyte maturity index (RMI) proportional to the amount of RNA in the reticulocytes. The RMI values, but not the reticulocyte percentage or absolute counts, correlated temporally with the rise in the absolute neutrophil counts in the posttransplantation period. In the majority of patients (12/20), the RMI value was the earliest indicator of bone marrow engraftment. The findings of this study demonstrate an important clinical utility of TO reticulocyte analysis by flow cytometry and indicate the diagnostic importance of the RMI measurement in the evaluation of erythropoietic activity in bone marrow transplant patients.
