| veiled cells | An antigen-presenting cell that has veil-like cytoplasmic processes and circulates in the blood and lymph. Synonym: veiled cells. (05 Mar 2000) |
|---|---|
| Gaucher cells | Large, finely and uniformly vacuolated cell's derived from the reticuloendothelial system, and found especially in the spleen, lymph nodes, liver, and bone marrow of patients with Gaucher's disease; Gaucher cell's contain kerasin (a cerebroside), which accumulates as a result of a genetically determined absence of the enzyme glucosylceramidase. (05 Mar 2000) |
| parafollicular cells | Cell's present between follicles or interspersed among follicular cell's; they are rich in mitochondria and are believed to be the source of thyrocalcitonin. Synonym: C cell, light cells of thyroid. (05 Mar 2000) |
| paraganglionic cells | Cell's of the embryonic sympathetic nervous system that become chromaffin cell's. (05 Mar 2000) |
| vero cells | A cell line derived from the kidney of the african green (vervet) monkey, cercopithecus aethiops; used primarily in virus replication studies and plaque assays. (12 Dec 1998) |
| germ cells | The reproductive cells in multicellular organisms. (12 Dec 1998) |
| parietal cells, gastric | Cells of the gastric glands which secrete hydrochloric acid and intrinsic factor. (12 Dec 1998) |
| giant cells, foreign-body | Multinucleated cells (fused macrophages), characteristic of granulomatous inflammation, which form around exogenous material in the skin. They are similar in appearance to langhans giant cells (giant cells, langhans), but foreign-body giant cells have more abundant chromatin and their nuclei are scattered in an irregular pattern in the cytoplasm. (12 Dec 1998) |
| giant cells, langhans | Multinucleated cells (fused macrophages) seen in granulomatous inflammations such as tuberculosis, syphilis, sarcoidosis, and deep fungal infections. They resemble foreign-body giant cells (giant cells, foreign body) but langhans giant cells contain less chromatin and their nuclei are arranged peripherally in a horseshoe-shaped pattern. Langhans giant cells occur frequently in delayed hypersensitivity. (12 Dec 1998) |
| mastoid air cells | Numerous small intercommunicating cavities in the mastoid process of the temporal bone that empty into the mastoid or tympanic antrum. Synonym: cellulae mastoideae, mastoid cells, mastoid sinuses. (05 Mar 2000) |
| mastoid cells | Numerous small intercommunicating cavities in the mastoid process of the temporal bone that empty into the mastoid or tympanic antrum. Synonym: cellulae mastoideae, mastoid cells, mastoid sinuses. (05 Mar 2000) |
| Gierke cells | Small cells characteristic of the substantia gelatinosa (lamina II) of the dorsal horn of the spinal cord. (05 Mar 2000) |
| vestibular hair cells | Cell's in the sensory epithelium of the maculae and cristae of the membranous labyrinth of the inner ear; afferent and efferent nerve fibres of the vestibular nerve end synaptically upon them; from the apical end of each cell a bundle of stereocilia and a kinocilium extend into the statoconial membrane of the maculae and the cupula of the cristae. (05 Mar 2000) |
| castration cells | Altered basophilic cells of the anterior lobe of the pituitary that develop following castration; the body of the cell is occupied by a large vacuole that displaces the nucleus to the periphery, giving the cell a resemblance to a signet ring. Synonym: signet ring cells. (05 Mar 2000) |
| Reed cells | Large cells of unknown origin, usually multinucleate, whose presence is the common histologic characteristic of hodgkin disease. (12 Dec 1998) |
