Immunohistochemical evaluation of prostaglandin E2 and vascular endothelial growth factor in canine cutaneous mast cell tumours
(Wiley-Blackwell Publishing, Inc, 2010-03-01)
Vascular endothelial growth factor (VEGF) and prostaglandin E2 (PGE-2) appear to play a critical role in tumour neovascularization. In this study, we have investigated the expression of VEGF and PGE-2 in 53 canine cutaneous ...
ULTRASTRUCTURAL SIMILARITY BETWEEN BAT AND HUMAN MAST-CELL SECRETORY GRANULES
(Karger, 1993-01-01)
Mast cells in the tongue of the bat (Artibeus lituratus) show a well-developed Golgi area and abundant mitochondria in the granule-free perinuclear cytoplasm. Rough endoplasmic reticulum profiles, free ribosomes, mitochondria, ...
Characteristics of the histamine release from hamster cheek pouch mast cells stimulated by lectins from Brazilian beans and concanavalin A
(1996-10-10)
We have characterized the histamine releasing effects of lectins extracted from Brazilian beans, in comparison to concanavalin A, in hamster cheek pouch cell suspensions containing mast cells. The lectins from Dioclea ...

Gap junctions between mast cells and fibroblasts in the developing avian eye
(1995-12-01)
Mast cells are present in the eye of chick embryos from the 14th day onward, displaying metachromatic granules, mainly in the iris anterior surface and pectinate ligament. Ultrastructurally these cells show electron-dense ...

Morphological alteration of peritoneal mast cells and macrophages in the mouse peritoneal cavity during the early phases of an allergic inflammatory reaction
(Academic Press Ltd, 2001-01-01)
We investigated the presence of mast cell granules in macrophages following an in vivo model of an allergic reaction. Injection of ovalbumin (100 mug) into the peritoneal cavity of sensitised mice produced a rapid (within ...

A comparison between the concentration of mast cells in squamous cell carcinomas of the skin and oral cavity
(SOC BRASILEIRA DERMATOLOGIA, 2010)
FUNDAMENTS: The lethality of squamous cell carcinomas (SCC) of the skin is considered low. SCC in the mouth is usually associated with poor prognosis. Current evidence suggests that mast cells in the normal tissue contribute ...
