[New methods for the studying of erythropoiesis in humans and animals]

New approaches to studying erythropoiesis in man and animals on the basis of a quantitative and qualitative analysis of this process in the erythroblastic islands of the bone marrow are shown. Experimental and clinical data are given, which reflect the results of testing these approaches. Ideas on physiological and compensatory erythropoiesis in the erythroblastic islands of the bone marrow and on the manifestations of its suppression in these intercellular associations are presented.
