Murine Marrow. Enucleate erythrocyte containing ribosomes and a few mitochondria (marrow reticulocyte) is in juxtaposition to marrow sinus wall. At this level, a large segment of adventitial reticular cell cytoplasm prevents most of the erythrocyte from juxtaposing to the abluminal surface of the endothelial lining cell. A probe at the right edge of the erythrocyte is in contact with endothelium and may show very early penetration of endothelial cell. In experimental models pharmacological doses of erythropoietin decreases adventitial cell cytoplasmic cover of the abluminal sinus wall and may improve access of the reticulocyte to the endothelial cell.
