[Appearance of phosphatase reticular cells in the spleen parenchyme of normal and tumor-bearing mice].
The splenic mouse parenchyma presents 3 reticular cells types revealed by histo-enzymatic technics: the phagocytic cells show a strong phosphatasic acid activity, the endothelial cells possess a phosphatasic alcalin or adenosine-triphosphatasic reaction, the perithelial cells are 5' nucleotidasic. These different cells are distributed by forming specific topographic structures in the splenic tissue. The phosphatasic alcalin reticular cells seem to be, with their distribution, characteristic elements of mouse spleen. Indeed the modifications in tumoral animal interest chiefly this cell category. In this case, the reticular cells form a deep and large membrane between marginal zone and perivascular lymphoid sheath of the white pulp. These different reticular cells probably react for the defense system of the animal.
