[Tissue nature of the lining of the lymph node sinuses].
The lymphatic nodes of intact albino rats were investigated electron microscopically. It was shown that the lymphatic sinuses were restricted by a layer of flattened cells; the basal membrane was absent. Certain distinctions in the structure of the cell lining sinuses and the reticular cells comprising the reticular base of the lymphoid tissue of the lymphatic node were found. The structure of the "sinus network" strands is shown. The structure of the cells of the sinuses lining is shown to be identical to the structure of cells of the vascular endothelium. It suggests the endothelial nature of the lining of the lymphatic node sinuses.
