| bronchic cells | One of the thin-walled saclike terminal dilations of the respiratory bronchioles, alveolar ducts, and alveolar sacs across which gas exchange occurs between alveolar air and the pulmonary capillaries. Synonym: alveoli pulmonis, alveolus, air cells, air vesicles, bronchic cells. (05 Mar 2000) |

| caco-2 cells | Human colonic adenocarcinoma cells that are able to express differentiation features characteristic of mature intestinal cells, such as enterocytes or mucus cells. These cells are valuable in vitro tools for studies related to intestinal cell function and differentiation. (12 Dec 1998) |
| packed human blood cells | Whole blood from which plasma has been removed; may be prepared any time during the dating period of the whole blood from which it is derived, but not later than six days after the blood has been drawn if separation of plasma and cell's is achieved by centrifugation. (05 Mar 2000) |
| pagetoid cells | Atypical melanocytes resembling Paget's cells, found in some cutaneous melanomas of the superficial spreading type. (05 Mar 2000) |
| Paget's cells | Relatively large, neoplastic epithelial cell's (carcinoma cell's) with hyperchromatic nuclei and palely staining cytoplasm; in Paget's disease of the breast, such cell's occur in neoplastic epithelium in the ducts and in the epidermis of the nipple, areola, and adjacent skin. (05 Mar 2000) |
| ganglion cells of dorsal spinal root | Pseudounipolar nerve cell bodies in the ganglia of the dorsal spinal nerve roots; the sensory spinal nerves are composed of the peripheral axon branches of these sensory ganglion cell's, whereas the central axon branch of each such cell enters the spinal cord as a component of the dorsal root. (05 Mar 2000) |
| ganglion cells of retina | The nerve cell's of the retina whose central processes (fibres) form the optic nerve; their peripheral processes synapse with the bipolar cell's and through them with the rod and cone cell's; these cell bodies are round or flask-shaped and vary considerably in size. (05 Mar 2000) |
| paneth cells | Epithelial cells found in the basal part of the intestinal glands (crypts of lieberkuhn). Paneth cells synthesise and secrete lysozyme and cryptidins. (12 Dec 1998) |
| Paneth's granular cells | Cell's, located at the base of intestinal glands of the small intestine, which contain large acidophilic refractile granules and may produce lysozyme. Synonym: Davidoff's cells. (05 Mar 2000) |
| 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) |
