“…Reticular cells in the capillary sheath can be classified into two types, I and II, on the basis of PA-TCH-SP reactivity. Previously, two types of sheathed retic- ular cells were differentiated in cat spleen by light-micro scopic studies [Riedel, 1932], The general reticular cell. (Retikulumzellen) which contains an oval nucleus with abundant chromatin in the center of the cytoplasm, is located in the periphery of the sheath.…”

“…The capillary sheath accumulates foreign particles; which, in the case of colloidal carbon, quickly reach the spleen after injection into the blood vessels [Li et al" 1929;Riedel, 1932: Solnitzky, 1937. Electron-microscopic stud ies show that the capillary sheath has a high number of endothelial cells, which contain numerous vimentin fila ments with slits between the endothelial ceils [Miyamoto et al, 1980;Blue and Weiss, 1981a.…”

“…Foreign particles in the blood are detained in the spleen as they pass through the delicate microcirculatory system and the structural organization of the reticular tissue [Burke and Simon. 1970;Miyamoto et a!., 1980: Fujita andKashimura, 1981], Sheathed arteries located in the red pulp consist of endothelium and the sur rounding sheath of reticular cells involved in the ingestion of foreign particles | Riedel, 1932;Solnitzky. 1937: Imai, 1954Fujita, 1974: Hatae.…”

The morphology of reticular cells of the sheathed arteries, in the red pulp of pig spleen, was studied by using transmission electron microscopy; and their histochemical reactivity with periodic acid-thiocarbohydrazide-silver proteinate (PA-TCH-SP). The phagocytic ability was evaluated by injecting colloidal carbon into the splenic artery. Reticular cells of the sheathed arteries were classified as type I and type II cells. Type I cells have a nucleus with scanty chromatin, and the cytoplasm reacts positively to PA-TCH-SP. The PA-TCH-SP-positive granules are considered to be subunits of β-glycogen particles based on their morphological features. Type II cells have a nucleus with abundant chromatin and are not stained by PA-TCH-SP. Both types of reticular cells are connected with reticular fibers. Results of the colloidal carbon injection showed that type I reticular cells did not ingest carbon particles during the time frame of the experiment, whereas type II reticular cells are phagocytic and ingested carbon.

Pericapillary Spongy Sheaths in the Human Spleen

Antisera to extracts of human hyaline cartilage allow distinct visualization of extracellular structures of adventitial sheaths around arterial capillaries in the red pulp and marginal zone in the human spleen. These pericapillary sheaths have a prominently spongy character indicating their essential filter function. In childhood they are most marked. In premature and stillborn infants they sometimes occupy whole stretches of pulp cords, whereas in old age they are frequently diminished to small formations lacking a distinctly spongy structure.
