In all eukaryotic cells the lysosomes or vacuoles play major cellular turnover roles, including autophagy where entire organelles are delivered to them for turnover. |
|
In all but one case, the axonal degeneration observed in these tissues was graded as very minimal and described as rare, scattered vacuoles. |
|
Vacuolar degeneration is autophagy's most characteristic feature, with cells exhibiting large vacuoles. |
|
As in other radiolaria, Acantharea have a gelatinous ectoplasm filled with vacuoles, separated from the inner cell mass by a fibrous capsular wall. |
|
Consequently, the lysosomes increase in size, producing huge vacuoles and impaired cell function is induced. |
|
No dots can be detected in the vacuoles but the tonoplast and the transvacuolar trabeculae of cytoplasm are labelled demonstrating that actin is present at this level. |
|
How the transition from a single "empty" central vacuole to numerous protein-filled vacuoles occurs has been the subject of much research and continuing debate. |
|
One of the more common desmid genera, the sickle-shaped Closterium, often contains gypsum crystals in cell vacuoles. |
|
Depending on the species, a paramecium has from one to several contractile vacuoles located close to the surface near the ends of the cell. |
|
Paramecium contains a reservoir of membrane-forming material in discoid vesicles for the purpose of producing food vacuoles. |
|
The food vacuoles form at the cytopharynx when the cytopharyngeal membrane and the discoid vesicles fuse. |
|
Many aquatic bacteria produce gas vacuoles, which are protein-bound structures that contain air and allow the bacteria to adjust their buoyancy. |
|
|
The changes consisted of disrupted myofibrils, increased numbers of lipid vacuoles in the sarcoplasm, and abnormally small mitochondria containing focal membrane disruptions. |
|
In the massively enlarged spleen, extramedullary hemopoiesis was prominent, with clusters of atypical megakaryocytes with vacuoles and erythrophagocytosis. |
|
Students should become familiar with and be able to use the terms cell wall, cell membrane, vacuoles, nucleus, cytoplasm, and chloroplasts. |
|
At this level, the histological changes seen were hepatocytic hypertrophy, vacuoles and necrosis, and necrotic hepatitis. |
|
They contain bubbles or vacuoles which increase the porosity and reduce density. |
|
The toxicant specifically targets the central nervous system, creating vacuoles that are apparent only through microscopic examination of very fresh brain tissue. |
|
However, the contributions of other membrane compartments, such as the plasma membrane, vacuoles, and endoplasmic reticulum, have not been investigated. |
|
Peroxidases are found in vacuoles, tonoplasts, plasmalemma including inside and outside of the cell wall. |
|
The vacuoles, or bubbles, in the cytoplasm likely indicate that the monocyte has become active and is trying to fight the infection. |
|
At the cytoproct, where the vacuoles are broken down and the waste material of digestion is ejected, the membrane material is retrieved and returned to the cytopharynx. |
|
The earliest sign of fat cell differentiation in the adipescent fibroblasts is the appearance of small cytoplasmic vacuoles. |
