Summary The proliferation kinetics of erythropoiesis and of myelopoiesis have been studied in a case of congenital dyserythropoietic anemia type II (HEMPAS) by means of quantitative 14-C autoradiography, Feulgen cytophotometry and 59-Fe ferrokinetics. Increased total erythropoietic activity and ineffective erythopoiesis was demonstrated by ferrokinetics. Quantitative 14-C autoradiography showed a generally delayed proliferation rate of erythroid cells, most evident in the polychromatic compartment. A deficiency of cell production of 25% was detected among the polychromatic erythroblasts. Part of this fraction is represented by cells still capable of passing to the successive stages of maturation. We conclude that only part of the deficiency of cell production in the polychromatic compartment represents real cell destruction. Most of the measured ineffectiveness is confined to later stages of maturation, such as orthochromatic erthroblasts and marrow reticulocytes.
