| adult T-cell leukaemia | Lymph nodes show a mixture of small and large atypical cells which are polymorphic and express nuclear pleiomorphism. Adult T-cell leukaemia is caused by HTLV-1 and is rare in the US and Europe but common in Japan. Tumour cells express CD2, CD3, CD5 and lack CD7. The most common chromosome change reported in adult T-cell leukaemia is presence of the 14q + marker (05 Mar 2000) |
|---|---|
| adult T-cell lymphoma | <tumour> An acute or subacute disease associated with a human T-cell virus, with lymphadenopathy, hepatosplenomegaly, skin lesions, peripheral blood involvement, and hypercalcaemia. Synonym: adult T-cell leukaemia. (05 Mar 2000) |
| adventitial cell | <pathology> Cell associated with the walls of small blood vessels: not a smooth muscle cell, nor an endothelial cell. (18 Nov 1997) |
| african green monkey kidney cell | <cell culture> Cells taken from the kidneys of the African green monkey Cercopithecus aethiops sabaeus and used to grow certain viruses like poliovirus. (05 Feb 1998) |
| air cell | 1. <botany> A cavity in the cellular tissue of plants, containing air only. 2. <anatomy> A receptacle of air in various parts of the system; as, a cell or minute cavity in the walls of the air tubes of the lungs; the air sac of birds; a dilatation of the air vessels in insects.

| 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) |
