Nephrocyte

Nephrocyte

 

the parenchymal and connective-tissue cells that have an excretory function in a number of invertebrates, such as turbellarians. Nephrocytes become loaded with excretions and then transport them out of the body. As the excretory apparatus developed over the course of evolution, the nephrocytes became concentrated in certain parts of the body, for example, in the walls of the nephridia, on the surface of the blood vessels in annelids, or in the pericardial cavity in mollusks.

Finally, storage cells include both pigment cells and nephrocytes.
The systemic nature of these high severity infections was evidenced by the appearance of the parasites in the nephrocytes in the gills (Fig.
negundo in streptozotocin-induced diabetic mice and found that it helped in the protection of hepatocytes, nephrocytes and pancreatic ([beta]-cells probably by its action against NF-kappaB and iNOS mediated inflammation.
This first volume covers the order Chilopoda, the centipedes, discussing such aspects as general morphology, integument and associated organs such as solitary epidermal glands and bioluminescence, musculature and locomotion, the excretory system including the maxillary organ of the Notostigmophora and nephrocytes, sense organs, reproduction, ecology, distribution, fossil history, and taxonomy.

For example, an increased number of nephrocytes in gill filaments, a blackened appearance of the gills, necrosis of gill cells resulting in narrowed or obstructed hemolymphatic vessels, the appearance of a space between the cuticle and the epithelial cells, which contains black electron-dense material and even fragmentation of nuclei within gill cells could be observed when P.
These clusters of stain appeared to be the developing thoracic nephrocytes, which stain in the adult.
In dissected adult flies, intense X-gal staining was found in the thoracic nephrocytes [ILLUSTRATION FOR FIGURE 8A OMITTED], abdominal pericardial cells [ILLUSTRATION FOR FIGURE 8B OMITTED], and two clearly demarcated regions of the ventriculus [ILLUSTRATION FOR FIGURE 8C OMITTED
Some regions of staining did not change in intensity (thoracic nephrocytes and pericardial cells).
