Mononuclear Phagocytes (kupffer Cells) and Endothelial Cells
The fine structural characteristics and phagocytic properties of peroxidase-positive and peroxidase-negative cells in rat hepatic sinusoids were investigated. Cells with a positive peroxidase reaction in the endoplasmic reticulum and the nuclear envelope make up approximately 40% of cells in rat hepatic sinusoids and have abundant cytoplasm containing numerous granules and vacuoles, and occasio...
متن کاملMurine Kupffer cells. Mononuclear phagocytes deficient in the generation of reactive oxygen intermediates
Murine Kupffer cells (KC) were isolated by a high yield collagenase perfusion technique. The morphology, surface markers, and secretory products were typical of macrophages in other tissues. However, KC released negligible levels of H2O2 and O-2, in contrast to peritoneal macrophages. KC oxygen consumption was not increased by agents triggering a respiratory burst in peritoneal cells. Moreover,...

The fine structural characteristics and phagocytic properties of peroxidase-positive and peroxidase-negative cells in rat hepatic sinusoids were investigated . Cells with a positive peroxidase reaction in the endoplasmic reticulum and the nuclear envelope make up approximately 407, of cells in rat hepatic sinusoids and have abundant cytoplasm containing numerous granules and vacuoles, and occas...
متن کاملRegulation of bone cells by particle-activated mononuclear phagocytes.
Bone loss around replacement prostheses may be related to the activation of mononuclear phagocytes (MNP) by prosthetic wear particles. We investigated how osteoblast-like cells were regulated by human MNP stimulated by particles of prosthetic material. Particles of titanium-6-aluminium-4-vanadium (TiAIV) stimulated MNP to release interleukin (IL)-1beta, tumour necrosis factor (TNF)alpha, IL-6 a...
متن کاملOsteoclast formation from mononuclear phagocytes: role of bone-forming cells
In a previous study, using co-cultures of embryonic bone rudiments stripped of periosteum, and mononuclear phagocytes of various sources, we found that multinucleated mineral-resorbing osteoclasts developed in vitro from radiosensitive mouse bone marrow mononuclear phagocytes (BMMP).
