What is subnuclear vacuolation?
Subnuclear vacuolated mucous cells show a distinctive appearance on haematoxylin and eosin staining. They are columnar cells of similar size to simple mucin-secreting cells, but have a central nucleus beneath which the cytoplasm has a uniform glassy eosinophilic appearance or contains a clear area.
What causes Vacuolation?
Cytoplasmic vacuolization (also called cytoplasmic vacuolation) is a well-known morphological phenomenon observed in mammalian cells after exposure to bacterial or viral pathogens as well as to various natural and artificial low-molecular-weight compounds.
What is mitochondrial Vacuolization?
Mitochondrial vacuolization is typically a sign of irreversible cell injury, signifying that the involved mitochondria are permanantly unable to generate ATP.
What does vacuolated cytoplasm mean?
Cytoplasmic Vacuolation. Vacuoles are areas of the cytoplasm which do not stain with Wright’s stain and appear as holes in the cytoplasm. Their composition may vary; some will contain remnants of bacterial digestion, autodigestion in an aging cell, while others may contain fat.
Where is Vacuolation take place?
Vacuolation, myelinopathies Although they may be seen in neuronal bodies and glial cells, most vacuoles typically occur in the white matter of the brain and myelinated peripheral nerves, mostly as a result of alterations to myelin.
What is vacuolation of cytoplasm?
What is a Vacuolated neutrophil?
The presence of vacuolated polymorphonuclear neutrophils in blood smears of patients suffering from infection appears to be associated with massive bacterial growth and to constitute a very early symptom of rapidly life-threatening septicaemia.
What are Vacuolated neutrophils?
What is vacuolar degeneration?
Vacuolar degeneration is a pathologic change which can occur in cells of different tissues. The. affected cells are distinguished by the presence of variously sized cytoplasmic vacuoles (up to several µ in diameter), outlined by a single membrane and containing substances of different kinds.
What are the function of vacuole?
A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
