Endothelium definition: a type of epithelium composed of a single layer of smooth, thin cells that lines the heart, blood vessels, lymphatics, and serous cavities.. See examples of ENDOTHELIUM used in a sentence.
Surface cells make tight junctional complexes between their neighbors, which create the first barrier against the external environment. Like other epithelial barriers in the human body, the corneal epithelium is a self-renewing tissue with a distinct stem cell niche residing in the limbal basal ...
(AJs). While TJs are composed ofoccludinandclaudinsproteins and located in the apical region, AJs are composed ofcadherinandintegrinand located in the apical or/and basolateral region of epithelium cells. TJs and AJs barriers block the entry of potentially active molecules into brain tissue, ...

The endothelium is a monolayer of cells on the posterior corneal surface that transports water from the stroma into the anterior chamber. This movement of water counters a natural tendency for the stroma to swell and is necessary to maintain a transparent cornea. Embryologic studies, in particular...
SARS-CoV-2 infection caused massive virus replication and dramatic organelles remodeling in alveolar epithelial cells, alone. While, viral infection affected endothelial cells in an indirect manner, which was mediated by infected alveolar epithelium. Proteomics analysis and TEM examinations showed viral ...
To date, no unique, robust marker for CEC identification has been identified. The standard phenotype markers (i.e., Na+/K+-ATPase and zonula occludes (ZO)-1) are not specific to CECs because they can be found in other corneal cells, such as the corneal epithelium. Recent studies have ...
The ontogeny of human haematopoietic stem cells (HSCs) is poorly defined owing to the inability to identify HSCs as they emerge and mature at different haematopoietic sites1. Here we created a single-cell transcriptome map of human haematopoietic tissues from the first trimester to birth and found...
