title: [Pathways of terminal erythrocyte differentiation in birds. An analysis of the intermediate forms].
abstract: The erythropoiesis during anemia is characterized by the reduction of the bone marrow period of cell development. Two immature forms, absent in the normal state, were shown to be present under anemia: basophilic erythroblasts and reticulocytes with basophilic cytoplasm. These forms are interposed between the bone marrow basophilic erythroblasts and erythrocytes. Some basophilic erythroblasts turn out in the peripheral blood and transform into basophilic reticulocytes there. The level of transcription in anemic animals during the transformation of basophilic erythroblasts into basophilic reticulocytes does not decrease and is higher than that in polychromatophilic erythroblasts. The total chromatin condensation does not reflect the decrease of the transcription level.
