| albuminous cell | A cell, especially of the salivary gland, that secretes a watery or thin albuminous fluid, as opposed to a mucous cell. Synonym: albuminous cell. (05 Mar 2000) |

| algoid cell | A cell appearing like cell's of algae, sometimes found in chronic diarrhoea. (05 Mar 2000) |
| alpha cell | <biology> A type of cell in the pancreas (in areas called the islets of Langerhans). Alpha cells make and release a hormone called glucagon, which raises the level of glucose (sugar) in the blood. (09 Oct 1997) |
| alveolar cell | Cell of the air sac of the lung. (18 Nov 1997) |
| alveolar cell carcinoma | <tumour> A carcinoma, thought to be derived from epithelium of terminal bronchioles, in which the neoplastic tissue extends along the alveolar walls and grows in small masses within the alveoli; involvement may be uniformly diffuse and massive, or nodular, or lobular; microscopically, the neoplastic cells are cuboidal or columnar and form papillary structures; mucin may be demonstrated in some of the cells and in the material in the alveoli, which also includes denuded cells; metastases in regional lymph nodes, and even in more distant sites, are known to occur, but are infrequent. Synonym: alveolar cell carcinoma, bronchiolar adenocarcinoma, bronchiolo-alveolar carcinoma, bronchioloalveolar adenocarcinoma. (05 Mar 2000) |
| amacrine cell | <cell biology> A class of neuron of the middle layer of the retina, with processes parallel to the plane of the retina. They are thought to be involved in image processing. (18 Nov 1997) |
| ameboid cell | A cell such as a leukocyte, having ameboid movements, with a power of locomotion. Synonym: wandering cell. Synonym: migratory cell. (05 Mar 2000) |
| amphotropic packaging cell lines | <cell culture, molecular biology> Clonal entities that express genes or act as viral vectors that infect cell lines to stably infect and then express genes of choice. Usually an amphotropic virus. (04 Nov 1997) |
| anaemia, sickle cell | A disease characterised by chronic haemolytic anaemia, episodic painful crises, and pathologic involvement of many organs. It is the clinical expression of homozygosity for haemoglobin s. (12 Dec 1998) |
| anaplastic cell | A cell that has reverted to an embryonal state, an undifferentiated cell, characteristic of malignant neoplasms. (05 Mar 2000) |
| anaplastic large cell lymphoma | <tumour> A form of lymphoma characterised by anaplasia of cells, sinusoidal growth, and immunoreactivity with CD30 (Ki-1 or Ber-H2). Synonym: Ki-1+ lymphoma. (05 Mar 2000) |
| animal cell culture | <cell culture> Mammalian cells are fragile and harder to grow than other cell types, but their large-scale culturing is an economic boon because it allows for the production of proteins that are otherwise difficult or expensive or unethical to extract from living organisms. The cells are immobilised on a substrate and then perfused with culture medium, The cells are in a free suspension which is very gently mixed and aerated. (12 Nov 1997) |
| animal cell immobilisation | <cell culture> Animal cells are widely used in biotechnology to produce genetically engineered proteins. However, they are more fragile than bacterial cells, and immobilising the cell facilitates the fermentation process. Many animal cells stick down flat on a suitable surface, hugging it as they would hug other cells or connective matrices in the body. If grown on suitable plastic surfaces, on glass or many ceramics, these cells will stick to them. In this way, they are easier to grow. (14 Nov 1997) |
| animalised cell | <zoology> The 8-16 cell early blastula of sea urchins has animal and vegetal poles, by manipulating the environmental conditions it is possible to shift more cells from vegetal to animal in their characteristics. (12 Nov 1997) |
| Anitschkow cell | A large mononuclear cell found in connective tissue of the heart wall in inflammatory conditions, especially in the Aschoff body. The ovoid nucleus contains a central chromatin mass appearing as a wavy bar in longitudinal section. Synonym: Anitschkow cell, Anitschkow myocyte, caterpillar cell. (05 Mar 2000) |
