Cytological Characteristics of Bone Marrow Reticular Cells, Tissue Macrophages and Monocytic Cell Line

Abstract

The bone marrow consists of a loose stroma made up of a wide meshwork of reticular cells which are a supporting element closely related to bone marrow hematopoiesis, while fixed tissue macrophages also stretch their long cytoplasmic processes, participate in formation of the reticular mesh and show avid phagocytosis (3, 7).Together with the sinus endothelia these kinds of cells constitute the reticuloendothelial system of the bone marrow. In the reticular meshworks, there exist hematopoietic cells, including monocytic cells which also have phagocytic capacity (3). However, there is little or no precise knowledge regarding the relationship of these stromal cells and phagocytic cells.
