Epithelial cells are a type of cells that make up the surfaces and linings of our body. They are like a protective layer that covers organs, skin, and blood vessels. These cells help in absorption, filtration, secretion, and prevention of harmful substances from entering our body.

epithelial cells which display functionality in vitro.
Stage I lactogenesis, or secretory initiation, occurs during pregnancy and is defined by the differentiation of mammary
alveolar epithelial cells into specialized secretory cells, termed lactocytes (1).
The researchers painstakingly examined how Alix exercises these functions to promote the correct assembly and positioning of specialized intercellular junctions
between epithelial cells called the tight junctions.
Sauerkraut is a good source of fermentable fiber aka prebiotics that is fuel for the commensal gut bacteria so that they can produce compounds (such as short chain fatty acids) that feed more commensal bacteria and feed
gut epithelial cells which are required to make the gut barrier.
These findings uncover the mechanism by which
normal epithelial cells recognize and eliminate oncogenic neighbors by cell competition.
It was also tested using the human
gastric epithelial cell line GES - 1 (more here on how human cell lines are commonly used in research) which was incubated with GABA and then treated with ethanol to induce cell injury.
This certainly applies to living tissues when multicellular assemblies such
as epithelial cells achieve complex morphogenetic processes.
Using macrophages and a variety of
epithelial cell types as models systems, his research employs genomic, proteomic, and cellular imaging approaches, coupled with computational biology strategies to identify the pathways modulated by nanoparticles and the implications of these pathways for human health.
Transient Silencing of 14 -3-3sigma promotes proliferation of p63 - positive progenitor cells isolated from human breastmilk in mammary
epithelial cell culture.
In the first half of pregnancy secretory differentiation (the differentiation of alveolar
epithelial cells into milk - secreting cells), ductal branching and lobular formation of the breast (mammogenesis) occur.
In the Intestine Chip, the epithelium forms villi - like projections lined by
polarized epithelial cells that undergo multi-lineage differentiation similar to that of intestinal organoids, however, these cells expose their apical surfaces to an open lumen and interface with endothelium.
Time - lapse movie of zebrafish lens
epithelial cells expressing GFP - histones and mCherry - zGem as they progress through the cell cycle.
In stark contrast to contemporary human influenza H1N1 viruses, the 1918 pandemic virus had the ability to replicate in the absence of trypsin, caused death in mice and embryonated chicken eggs, and displayed a high - growth phenotype in human
bronchial epithelial cells.
(C) Degree of branching and number of mammary
epithelial cell layers in the mammary tissue formed by mammary cells infected with miR - 150.
Here we describe a method for fabricating a primary human Small Intestine - on - a-Chip (Intestine Chip)
containing epithelial cells isolated from healthy regions of intestinal biopsies.
Zinc is essential to the cellular apparatus that holds
epithelial cells together and thus helps protect our animals against their environment.
Using a crystal structure of a complex protein compound of botulinum neurotoxin, Rongsheng Jin, associate professor of physiology & biophysics at UC Irvine, and collaborators found that these compounds — called clostridial hemagglutinin (HA)-- bind with
epithelial cell proteins in the intestines of patients, which initiates a process that disrupts the close intercellular seals so that the complex toxin molecules can slip through the epithelial barrier.
The article «Estrogenic compounds reduce influenza A virus replication in primary human
nasal epithelial cells derived from female, but not male, donors» is published ahead - of - print in the American Journal of Physiology — Lung Cellular and Molecular Physiology.

Additional research will show whether
other epithelial cells such as skin also partake of this self - healing method.
