[The ways of transmission of liver cell cytoplasma components to differential erythroblasts in erythropoiesis].
Intercellular interactions consisting of cytoplasmatic bridges and net-like ductal structures were revealed while electron-microscopic investigation in erythropoietic foci of hepar of mammals and amphibians. Hepatic microenvironment cells may influence the erythroblasts via the vascular net of the blood-producing foci and via the cytoplasm of interspaced cells of microenvironment of another kind. The presence of such morphologic structures makes possible to suppose the possibility of transit of ribosomes, protein molecules, lipids and other components of the microenvironmental cells cytoplasm into differentiating erythroblasts. Significant acceleration of maturing process of the red blood cells in erythropoietic foci was promoted by entrance of the cytoplasm components of the microenvironmental cells into erythroblasts.
