In recent research done in mice, it was found that the cleavage of PrP proteins in peripheral nerves causes the activation of myelin repair in Schwann Cells and that the lack of PrP proteins caused demyelination in those cells.

Natural Killer Cells ( NK ) often lack antigen specific cell surface receptors and therefore are part of innate immunity i. e. able to react immediately with no prior exposure to the pathogen.

In Cell: Homeostatic Expansion of T Cells during Immune Insufficiency Generates Autoimmunity they showed that when short lived T cells were replaced during a state of too few long lived T-cells ( Memory T cell ), because of lack of infections, the risk of developing autoimmune diseases will increase.

Cells lacking Aurora B fail to arrest in metaphase even when chromosomes lack microtubule attachment.

Cells with impaired function of Ndc80 ( using RNAi, gene knockout, or antibody microinjection ) have abnormally long spindles, lack of tension between sister kinetochores, chromosomes unable to congregate at the metaphase plate and few or any associated kMTs.

Sieve tubes are not known as ' Real Cells ' as they lack a substantial amount of cytoplasm.

Cells that lack caveolins also lack caveolae.

# Ex vivo, which means " outside the body " – Cells from the patient's blood or bone marrow are removed and grown in the laboratory.

Cells interact though plasmodesma ( ta ), which are inter-connecting channels of cytoplasm that connect to the protoplasts of adjacent cells across the cell wall.

Cells with secondary cell walls are rigid.

Cells that have temporarily or reversibly stopped dividing are said to have entered a state of quiescence called G < sub > 0 </ sub > phase.

Cells using water-based electrolytes are usually limited to cell potentials less than about 2. 5 volts, because the very powerful oxidizing and reducing agents which would be required to produce a higher cell potential tend to react with the water.

Cells found in a ganglion are called ganglion cells, though this term is also sometimes used to refer specifically to retinal ganglion cells.

Cells may be exposed to UV radiation or mutagenic chemicals, and mutants with desired characteristic are then selected.

Cells produced by the first few divisions of the fertilized egg are also totipotent.

Cells that have not been written to before are assumed to be filled with the blank symbol.

* Lysosomes or " Suicide Cells " are involved in cellular digestion.

Cells such as fibroblasts are responsible for synthesizing ECM molecules.

** John McCarthy is kidnapped in Beirut ( released in August 1991 ) – 3 others are found dead ; Revolutionary Cells ( RZ ) claims responsibility in retaliation for the U. S. bombing of Libya.

Cells are classified into two categories: simple, non-nucleated prokaryotic cells, and complex, nucleated eukaryotic cells.

Cells are able to survive outside the body for a limited amount of time, which makes them ideal indicator organisms to test environmental samples for fecal contamination.

Cells comparing a candidate to themselves are left blank.

Cells are solitary or united into colonies of various kinds, which may be linked by siliceous structures ; mucilage pads, or stalks ; mucilage tubes ; amorphous masses of mucilage and threads of polysaccharide ( chitin ), which are secreted through strutted processes.

Cells showing linear spatial summation are termed X cells ( also called parvocellular, P, or midget ganglion cells ), and those showing non-linear summation are Y cells ( also called magnocellular, M, or parasol retinal ganglion cells ), although the correspondence between X and Y cells ( in the cat retina ) and P and M cells ( in the primate retina ) is not as simple as it once seemed.

Cells that possess this faculty are generally referred to as amoeboids.

Cells are not able to take in glucose, amino acids and fatty acids.

Cells are also angled up about 13 ° from horizontal to prevent honey from dripping out.

Cells of the epithelium are bound basally to a laminal matrix and apically to an extraembryonic matrix.

Cells from the same VC are always sent sequentially.

The incorporation of smaller cells within larger ones resulted in the development of yet more complex cells called eukaryotes .< ref > Cells within colonies became increasingly specialized, resulting in true multicellular organisms.

On May 31, 2011 Jello Biafra and the Guantanamo School of Medicine released the CD Enhanced Methods of Questioning with a song about Henrietta Lacks and the HeLa immortal cell line called " The Cells That Will Not Die ".

Cells that are not in the germline are called somatic cells.

Cells can form intergrin mediated attachments sites called focal adhesions.

Cells that synthesize melanins are called melanocytes, and also the retinal pigment epithelium cells, whereas cells that have merely engulfed the melanosomes are called melanophages.

Later work by Eccles et al., provided evidence that these interneurones, which they called “ Renshaw Cells ,” are stimulated by acetylcholine from motor neurons.

Cells called fibroblasts are widely dispersed in this tissue ; they are irregular branching cells that secrete strong fibrous proteins and proteoglycans as an extracellular matrix.

Cells derived from competent source tissue are cultured to form an undifferentiated mass of cells called a callus.

Cells sometimes enter a state of resistance to signals sent, as part of a process called apoptosis, to instruct cells to destroy themselves.

On December 30, 2009, the band posted an announcement on their Myspace about a " new project " that they called Blood Cells. This is a band featuring both Jonah Bergman and Ryann Donnelly, as well as two new members.

A recent radionucleotide study called BVA-100, Blood Volume Analysis is the only FDA approved instrument that provides a measure of Red Blood Cells and Plasma with 98 % accuracy.

Photosensitive ganglion cells, also called photosensitive Retinal Ganglion Cells ( pRGC ), intrinsically photosensitive Retinal Ganglion Cells ( ipRGC ) or melanopsin-containing ganglion cells, are a type of neuron ( nerve cell ) in the retina of the mammalian eye.
