Ultrastructure of human mast-cell granules
Journal of Ultrastructure Research, 1968The ultrastructure of the mast-cell granule was studied in skin specimens of urticaria pigmentosa. The granules showed mainly two structural components, i.e., lamellae of a maximal width of 125 A and a fine granular material. The mature granules showed parallel-arranged lamellae, each of which had a periodicity of 60 A. The lamellae formed multilayered

Lysosomal enzymes in the juxtaglomerular cell granules
Experientia, 1979In addition to the already known acid phosphatase and beta-glucuronidase, 2 other lysosomal enzymes: aryl sulphatase and N-acetyl-beta-glucosaminidase were localized by histochemical methods in the renin-containing granules of the mouse juxtaglomerular cells.

Specification of Granule Cells and Purkinje Cells
2019Granule cells and Purkinje cells are the major populations of neurons in the cerebellum. Their specification depends on a combination of regional identity and spatiotemporal cues. These are conferred by patterning systems in the early embryo that determine anteroposterior and dorsoventral positional coordinates and an age-dependent signal (or signals ...

Effect of Age on Mast Cell Granules
International Archives of Allergy and Applied Immunology, 2009Padawer has proposed that rat mast cells in the peritoneal cavity have an extended lifespan and under normal conditions exhibit little turnover of their secretory granules. We have examined several constituents of the granules as part of a study of the structure and function of these organelles. The previously described increase in volume of mast cells

The occurrence of intramitochondrial granules in nerve cells
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1968The mitochondria of spinal cord motoneurons of normal rats have been studied and compared with those of animals given 2.5 mg/kg of strychnine sulfate. The mitochondria in the motoneurons of the treated animals exhibited opaque granules in the matrix.

1996
Abstract From a casual scan of the literature, it appears that rodent cerebellar granule cell cultures are being used in increasing numbers to address different questions in neurobiology. There are good reasons for this: the cultures are relatively easy to prepare, the starting material is neonatal rat pup thus avoiding the use of ...

Granulated Round Cell Tumor of Cats
Veterinary Pathology, 1993Morphologic and biologic features of five feline granulated round cell tumors were compared with those previously reported to be of globule leukocyte and large granular lymphocyte origin. The five cats ranged from 6 to 9 years of age and presented with nonspecific gastrointestinal signs.

Granule-Mediated Cytolysis of Target Cells
1988The lysis of target cells attacked by cytotoxic T cells appears to be caused by two possibly related phenomena, namely the formation of transmembrane pores in the target cell’s membrane and the cleavage and release of the target cell’s nuclear DNA. At present it is not entirely clear how these effects are mediated at a molecular level.
