Epithelial in a sentence

Tissue separation can also occur via more dramatic cellular differentiation events during which epithelial cells become mesenchymal (see Epithelial-mesenchymal transition ).

For the new study, the scientists first wanted to see what happened when epithelial cells were introduced to a virus-like challenge.

Both these drugs and aromatic amines may cause retinal damage by interfering with a pathway important to the survival and homeostasis of retinal pigment epithelial cells, the authors say.

In order to test how the rhinovirus and virus interact, the researchers created human airway tissue from stem cells that give rise to epithelial cells, which line the airways of the lung and are a chief target of respiratory viruses.

It is an important immune modulator that has been shown to facilitate cellular signaling, epithelial repair, and other critical processes that enhance the immune response and help defend the body against infection and cancer.

We know that the virus enters the body through epithelial cells in the respiratory tract.

Scimeca M, Giannini E, Antonacci C, Pistolese C, Spagnoli L, Bonanno L. Microcalcifications in breast cancer: an active phenomenon mediated by epithelial cells with mesenchymal characteristics.

Their findings could pave the way to understanding the three-dimensional organization of epithelial organs and lead to advancements in tissue engineering.

The researchers were able to prove that no acute damage is caused to the lung if lung epithelial cells come into contact with graphene oxide (GO) or graphene nanoplatelets (GNP).

This concept is predicated on the fact that colostrum which is contained in the milk, reduces the risk of death from hypothermia and helps in epithelial recovery while protecting the baby from infectious diseases.

Although mucins of epithelial origins stain with PAS, mucins of connective tissue origin have so many acidic substitutions that they do not have enough glycol or amino-alcohol groups left to react with PAS.

As noted above, epithelial sodium channels ENaC that are expressed along the length of cilia regulate fluid level surrounding the cilia.

Cadherins bind to other cadherins in a like-to-like manner: E-cadherin (found on many epithelial cells) binds preferentially to other E-cadherin molecules.

Development The two main components of the thymus, the lymphoid thymocytes and the thymic epithelial cells, have distinct developmental origins.

Due to this the lack of connective tissue surrounding the parabronchi and adjacent parabronchial lumen, they exchange blood capillaries or avascular epithelial plates.

During the process of epithelial differentiation, cells become cornified as keratin protein is incorporated into longer keratin intermediate filaments.

Epithelial sodium channels ENaC that are specifically expressed along the entire length of cilia apparently serve as sensors that regulate fluid level surrounding the cilia.

Every gland is formed by an ingrowth from an epithelial surface.

For example, mouse thymic epithelial cells (TECs) are known to react with antibodies for keratin 5, keratin 8, and keratin 14. These antibodies are used as fluorescent markers to distinguish subsets of TECs in genetic studies of the thymus.

Further esterification into all-"trans" retinyl esters allow for storage of all-trans-retinol within the pigment epithelial cells to be reused when needed.
