Epithelial cells ( which are non-circulating ) normally have active integrins at their cell membrane, helping maintain their stable adhesion to underlying stromal cells that provide signals to maintain normal functioning.

The growth of cervical loop cells into the deeper tissues forms Hertwig's Epithelial Root Sheath, which determines a tooth's root shape.

Epithelial cells of the lung and breast both contain keratin-7, but some other glandular epithelia, such as those of the colon and prostate, do not.

Epithelial cells, specifically type II pneumocytes, also internalize conidia which traffic to the lysosome where ingested conidia are destroyed.

The research used rat PC12 cells and Human Lens Epithelial ( HLE ) cells cultured for four hours on the surface modified porous silicon.

Photorefractive keratectomy ( PRK ) and Laser-Assisted Sub-Epithelial Keratectomy ( or Laser Epithelial Keratomileusis ) ( LASEK ) are laser eye surgery procedures intended to correct a person's vision, reducing dependency on glasses or contact lenses.

Epithelial to Mesenchmyal Cell Transition – loss of cell adhesion leads to constriction and extrusion of newly mesenchymal cell.

* ( 8010 – 8040 ) Epithelial neoplasms, NOS

* Epithelial sodium channel blockers: amiloride and triamterene.

Epithelial tissue helps to protect organisms from microorganisms, injury, and fluid loss.

Epithelial tissue includes, but is not limited to, the surface layer of skin, glands and a variety of other tissue that lines the cavities and organs of the body.

SPM serves as a surface receptor for immunoglobulins and some bacteria and is an activator of Epithelial Growth Receptors.

Epithelial atypia or dysplasia may be present.

Many cells, bacteria, and other microorganisms are transparent to visible light and must be stained for microscopic investigation.

Many of the cells and microorganisms which are transparent to visible light, absorb or reflect the much shorter wavelengths of the ultraviolet spectrum.

But they are still enclosed in their larval cells and remain there throughout the summer, fall, and winter.

At the present time we do not know by what biochemical mechanism TSH acts on the thyroid, but for bio-assay of the hormone there are a number of properties by which its activity may be estimated, including release of iodine from the thyroid, increase in thyroid weight, increase in mean height of the follicular cells and increase in the thyroidal uptake of Af.

For this step the computer memory is separated into three regions: cells in the W-region are used for storage of the forms in the text-form list ; ;

cells in the X-region and Y region are reserved as information cells for text forms.

The address Af and the number of cells required to store the form are written in Af ; ;

similarly, as many cells are added as are required.

The list of text forms in the W-region of memory and the contents of the information cells in the X and Y-regions are no longer required.

They are often involved in teaching anatomy, and research into certain systems, organs, tissues or cells.

In successive microsporogenesis, walls are laid down separating the daughter cells after each division.

* Other apomorphic characters of the order according to Stevens are: the presence of chelidonic acid, anthers longer than wide, tapetal cells bi-to tetra-nuclear, tegmen not persistent, endosperm helobial, and loss of mitochondrial gene sdh3.

The motor neuron diseases ( MND ) are a group of neurological disorders that selectively affect motor neurons, the cells that control voluntary muscle activity including speaking, walking, breathing, swallowing and general movement of the body.

They are distinguished by the nerve cells affected ( upper and lower motor neuron ), and the symptoms that result from this damage:

In vertebrates, the axons of many neurons are sheathed in myelin, which is formed by either of two types of glial cells: Schwann cells ensheathing peripheral neurons and oligodendrocytes insulating those of the central nervous system.

Nodes of Ranvier are short fragments of unmyelinated segments of the axon, which are found periodically in between the cells of the myelin sheath.

For example the standard glutamic acid ( glutamate ) and the non-standard gamma-amino acid gamma-amino-butyric acid ( GABA ) are respectively the brain's main excitatory and inhibitory neurotransmitters, hydroxyproline-a major component of the connective tissue collagen-is synthesised from proline, the standard amino acid glycine is used to synthesise porphyrins used in red blood cells, and the non-standard carnitine is used in lipid transport.

In general, external alpha radiation is not harmful since alpha particles are effectively shielded by a few centimeters of air, a piece of paper, or the thin layer of dead skin cells.

By endocytosis or phagocytosis, exogenous antigens are taken into the antigen-presenting cells ( APCs ) and processed into fragments.

Some T cells are specific for the peptide: MHC complex.

Cytokines are substances that can activate cytotoxic T lymphocytes ( CTL ), antibody-secreting B cells, macrophages, and other particles.
