[Mechanism of inhibition of erythropoiesis during post-transfusion polycythemia].
In mouse with posttransfusion polycytemia, depression of erythropoiesis suggests that, in response to erythrocytes transfusion, not only the differentiation of erythropoietin-sensitive cells is interrupted (cessation of inflow of the labelled erythrocytes into the circulation on the 8th day), but the proligeration of differentiated erythroid precursors is also inhibited (fall of amount of labelled erythrocytes during first days). This was corroborated by analysis of the experimental data with the aid of mathematical model of erythropoiesis. The model revealed that, in posttransfusion polycytemia, division of 40 percent of all divisionable erythroid precursors was halted.
