cell adhesion molecule

ABBR: CAM. Any molecule that traverses the cell membrane and contains a chemical domain that binds it to other cells or to the extracellular matrix.

cell bank

SEE: under bank.

cell-based therapy

The use of living cells as therapeutic agents. Possible examples include dendritic cells, to initiate immune responses to particular cancers; stem cells, as a source for tissue replacement, repair, or gene delivery; and tumor cells, to create antigen targets for the immune system.

cell coat

A colloquial term for glycocalyx.

cell counter, electronic

An electronic instrument used to count blood cells, employing either an electrical resistance or an optical gating technique. SEE: flow cytometry.

cell division

The fission of a cell. SEE: meiosis and mitosis for illus.


Pertaining to fluids or tissues that contain no cells or in which all the cells have been disintegrated by laboratory treatment.

cell growth cycle

SEE: under cycle.

cell kill

In antineoplastic therapy, the number of malignant tumor cells destroyed by a treatment.

cell line

A group of identical cells that can be maintained in the laboratory indefinitely because they are able to thrive and reproduce themselves in vitro.

cell mass

SEE: under mass.


(sĕl″ō-bī′ōs) A disaccharide resulting from the hydrolysis of cellulose.


(se-loyd′ĭn) Pyroxylin.


(sĕl′ō-fān) A thin, transparent, waterproof sheet of cellulose acetate. It is used as a dialysis membrane.

cell-penetrating peptide

SEE: under peptide.

cell phone, cellular phone

A portable telephone, used in the health professions in, for example, ambulance-to-hospital communications and in 12-lead electrocardiogram transmission in some emergency medical systems. Many people speculate that the use of cellular phones may increase the risk of cancers of the brain (such as gliomas or meningiomas), but no correlation between moderate usage and cancer has been definitively identified. In 2011, the International Agency for Research on Cancer (IARC) classified mobile phone radiation as Group 2B (possibly carcinogenic), not Group 2A (probably carcinogenic). That means that there may be some risk of carcinogenicity and that therefore further research must be conducted into the long-term, heavy use of mobile phones. Also in 2011, the World Health Organization, the parent organization of IARC, added that no adverse health effects had yet been established as being ...
