| virus-transformed cell | A cell that has been genetically changed to a tumour cell, the change being subsequently tramsmitted to all descendent cell's; cell's transformed by oncornaviruses continue to produce virus in high concentration without being killed; DNA tumour virus-transformed cell's develop (along with other changes) tumour-associated antigens and rarely produce virus.

| CD8 cell | <immunology> One type of T-lymphocyte which bears the CD8 molecular marker on its surface. Some CD8 cells recognise and kill cancerous cells and those infected by intracellular pathogens (some bacteria, viruses and mycoplasma). These cells are called cytotoxic T-lymphocytes (see). (09 Oct 1997) |
| glomerulosa cell | A cell of the zona glomerulosa of the adrenal cortex that is the source of aldosterone; the cell's are arranged in spherical or oval groups. (05 Mar 2000) |
| cell | <cell biology> An autonomous self replicating unit (in principle) that may constitute an organism (in the case of unicellular organisms) or be a sub unit of multicellular organisms in which individual cells may be more or less specialised differentiated) for particular functions. The individual units from which tissues of the body are formed. All living organisms are composed of one or more cells. (26 Mar 1998) |
| cell aggregation | The phenomenon by which dissociated cells intermixed in vitro tend to group themselves with cells of their own type. (12 Dec 1998) |
| cell aging | The decrease in the cell's ability to proliferate with the passing of time. Each cell is programmed for a certain number of cell divisions and at the end of that time proliferation halts. The cell enters a quiescent state after which it experiences cell death via the process of apoptosis. (12 Dec 1998) |
| cell behaviour | <cell biology> General term for activities of whole cells such as movement, adhesion and proliferation, by analogy with animal behaviour. (18 Nov 1997) |
| cell biology | <study> The study of the internal workings of cells at the microscopic and molecular level - it is closely linked to molecular biology. (16 Dec 1997) |
| cell body | Used in reference to neurons, the main part of the cell around the nucleus excluding long processes such as axons and dendrites. (18 Nov 1997) |
| cell-bound antibody | A term used for antibody on the surface of cells that may be bound either through antigen combining sites or other sites such as the Fc region. (05 Mar 2000) |
| renal cell cancer | Cancer that develops in the lining of the renal tubules, which filter the blood and produce urine. Also called renal cell carcinoma. (12 Dec 1998) |
| renal cell carcinoma | <oncology, tumour> The most common form of kidney cancer which occurs when the cells lining the renal tubule undergo cancerous changes. There are approximately 18,000 new cases of renal cell carcinoma (hypernephroma) per year in the U.S. With about 8,000 deaths annually. Smoking is considered a major risk factor. Kidney dialysis patients are at increased risk for the development of hypernephroma. Family history for renal cell carcinoma is also considered a risk factor. Symptoms include haematuria, flank pain, abdominal pain, back pain, weight loss and abdominal swelling. (27 Sep 1997) |
| cell bridges | Slender cytoplasmic strands connecting adjacent cells; in histological sections of the epidermis and other stratified squamous epithelia, the bridge's are processes attached by a desmosome and are shrinkage artifacts of fixation; true bridge's with cytoplasmic confluence exist between incompletely divided germ cells. Synonym: cell bridges, cytoplasmic bridges. (05 Mar 2000) |
| cell centre | Microtubule organising centre of the cell, the pericentriolar region. (18 Nov 1997) |
| cell cloning | The process of producing a group of cells (clones), all genetically identical, from a single ancestral cell. (12 Dec 1998) |
