| LAF | laminar air flow; Latin American female; leukocyte-activating factor; lymphocyte-activating factor |
|---|---|
| LAFR | laminar air flow room |
| LAFU | laminar air flow unit |
| LAL | left axillary line; Limulus amebocyte lysate; low air loss; lysosomal acid lipase |
| LALB | low air-loss bed |
| granulosa lutein cells | Cell's derived from the membrana granulosa of a mature ovarian follicle that secrete both oestrogen and progesterone, and form the major component of the corpus luteum. (05 Mar 2000) |
|---|---|
| chief cells, gastric | Epithelial cells that line the basal half of the gastric glands. Chief cells synthesise and secrete pepsinogen, a precursor of the enzyme pepsin. (12 Dec 1998) |
| mesoglial cells | Neuroglial cells of mesodermal origin. See: microglia. Synonym: mesoglial cells. Origin: meso-+ G. Glia, glue (05 Mar 2000) |
| great alveolar cells | Cuboidal cell's connected with the squamous pulmonary alveolar cell's and having in their cytoplasm lamellated bodies (cytosomes) that represent the source of the surfactant that coats the alveoli. Synonym: granular pneumonocytes, type II cells. (05 Mar 2000) |
| peritubular contractile cells | Flattened smooth muscle-like cell's of mesodermal origin that lie just outside the basal lamina of the seminiferous tubule. Synonym: peritubular contractile cells. (05 Mar 2000) |
| Rieder cells | Abnormal myeloblasts (12 to 20 um in diameter) in which the nucleus may be widely and deeply indented (i.e., suggestive of lobulation), or may actually be a bi-or multi-lobate structure; such cell's are frequently observed in acute leukaemia, and probably represent a more rapid maturation of the nucleus than that of the cytoplasm. (05 Mar 2000) |
| cho cells | Cell line derived from the ovary of the chinese hamster, cricetulus griseus. The species is a favourite for cytogenetic studies because of its small chromosome number. The cell line has provided model systems for the study of genetic alterations in cultured mammalian cells. (12 Dec 1998) |
| Rindfleisch's cells | An obsolete eponym for eosinophilic leukocyte. (05 Mar 2000) |
| gustatory cells | Darkly staining cell's in a taste bud that appear to have extending into the gustatory pore long hair-like microvilli containing a number of closely packed microtubules; the taste cell's stand in synaptic contact with sensory nerve fibres of the facial, glossopharyngeal, or vagus nerves. Synonym: gustatory cells. (05 Mar 2000) |
| Rolando's cells | The nerve cell's in Rolando's gelatinous substance of the spinal cord. (05 Mar 2000) |
| chromaffin cells | Cells that store epinephrine secretory vesicles. During times of stress, the nervous system signals the vesicles to secrete their hormonal content. Their name derives from their ability to stain a brownish colour with chromic salts. Characteristically, they are located in the adrenal medulla and paraganglia (paraganglia, chromaffin) of the sympathetic nervous system. (12 Dec 1998) |
| rosette-forming cells | T lymphocytes with an affinity for sheep erythrocytes and which, when suspended in serum, bind the uncoated, nonsensitised erythrocytes in a rosette formation. (05 Mar 2000) |
| microglia cells | <pathology> A part of the neuroglia. It consists of small glial cells which migrate through nerve tissue and remove waste products by phagocytosis. (09 Oct 1997) |
| middle cells | The middle group of air cells of the ethmoidal sinus's; each sinus communicates with the middle meatus of the nasal cavity. Synonym: sinus ethmoidales mediae, cellulae mediae, middle cells, middle ethmoidal sinuses. (05 Mar 2000) |
| midget bipolar cells | Bipolar cell's in the inner nuclear layer of the retina that synapse with individual cone cell's in the outer plexiform layer; other larger bipolar cell's in the inner nuclear layer synapse with both rod and cone cell's; the axons of both types synapse in the inner plexiform layer with the dendrites of the ganglion cell's.
