Secretory granules, which fill the apices of the epithelial cells, are electron dense and released into the lumen by a merocrine secretory process. Narrow intercellular canaliculi separate each epithelial cell and are sealed by tight junctions at the luminal aspect. Basally, leukoctyes are ...
These included apparent disruptions to epithelial tight junctions and vascular integrity. Changes were also noted in the choroid plexus per se, with losses in pericyte markers and increases in macrophage infiltration. Others have also observed that the blood-spinal cord barrier is damaged in ALS ...
iPSC-derived brain microvascular endothelial cells were successfully reprogrammed from human omental stromal cells. Figure1shows a 500 µm wide channel containing iBMECs after 2 days of growth. The inset containing fluorescent images shows the successful development of tight junctions and blood brain b...
In this study, determination methods of monitoring location in water distribution system were suggested and applied to real test bed. Small block of Gwangtan water distribution system is consisted of 582 pipes, 564 junctions, 1 reservoir... YG Park,SG Jung,HJ Kwon - 《Journal of the Korean ...
“The part of the gingiva which is firmly attached to the underlying tooth and bone and is stippled on the surface” [1]. WAG extends from the mucogingival junction (MGJ) and to the free gingival groove. It is characterized by firmness, density, stippling, and a tight connection to the ...
Ultrastructural examination revealed abundant pinocytotic vesicles within and conspicuous tight junctions between slender cytoplasmic processes which, in turn, were encased by discontinuous basal lamina. FISH analysis confirmed loss of at least part of one chromosome 22q. This observation calls attention ...
Fugita has compared taste bud chemoreceptors and those of the gut [1]. All the duodenal chemoreceptor cells have apical and basolateral domains, as do most (but not all) taste cells. These domains are delineated by a continuous ring of fibrous protein linking the cells, the tight junctions ...
About 60 years ago, impurity doping of bulk Si was established to introduce majority charge carriers, creating p/n junctions as fundamental building blocks of Si-based electronic devices. The discovery of swStiiiozh2.ene-DatchloeedtnraotirpcloeoadlnnletvidsnensisnitogiolhSindtiNa-isnlCttaS/otSie...
giving rise to mature cells. When they undergo apoptosis and are shed into the lumen, neighboring cells reform tight junctions to maintain cell polarization, cell-to-cell communication, a highly organized tissue structure, stabilization of the epithelial barrier, cell survival, and differentiation [10...
CSF is able to diffuse from the ventricles into the centralnervous system. The cells surrounding the choroid plexus are connected by tight junctions, which prevent the leakage of substances and fluids from the blood vessels into the CSF. This protects against the unregulated entry of potentially ha...
