| TD | the time required to double the number of cells in a given population; thermal death time |
|---|---|
| TVC | timed vital capacity; total viable cells; total volume capacity; transvaginal cone; triple voiding c... |
| TWBC | total white blood cells; total white blood count |
| Verc | vervet (African green monkey) kidney cells |
| VK | vervet (African green monkey) kidney cells |
| 3t3 cells | A cell line derived from fibroblasts of disaggregated swiss mouse embryos. The line is a valuable in vitro host system for oncogenic virus transformation studies since 3t3 cells possess a high sensitivity to contact inhibition. (12 Dec 1998) |
|---|---|
| follicular ovarian cells | Cell's of an ovarian follicle that surround the developing ovum; they form the stratum granulosum ovarii and cumulus oophorus. (05 Mar 2000) |
| langerhans cells | Recirculating, dendritic, antigen-presenting cells containing characteristic racket-shaped granules (birbeck granules). They are found principally in the stratum spinosum of the epidermis and are rich in class II major histocompatibility complex molecules. (12 Dec 1998) |
| Langerhans' cells | Dendritic clear cell's in the epidermis, containing distinctive granules that appear rod-or racket-shaped in section, but lacking tonofilaments, melanosomes, and desmosomes; they carry surface receptors for immunoglobulin (Fc) and complement (C3), and are believed to be antigen fixing and processing cell's of monocytic origin; active participants in cutaneous delayed hypersensitivity. (05 Mar 2000) |
| Langhans' cells | Multinucleated giant cell's seen in tuberculosis and other granulomas; the nuclei are arranged in an arciform manner at the periphery of the cell's. Synonym: Langhans'-type giant cells. Synonym: cytotrophoblastic cells. (05 Mar 2000) |
| Langhans'-type giant cells | Multinucleated giant cell's seen in tuberculosis and other granulomas; the nuclei are arranged in an arciform manner at the periphery of the cell's. Synonym: Langhans'-type giant cells. Synonym: cytotrophoblastic cells. (05 Mar 2000) |
| foveolar cells of stomach | Theca cell's of the foveolae of the stomach. (05 Mar 2000) |
| Leishman's chrome cells | Basophilic granular leukocytes (basophils) observed in the circulating blood of some persons with blackwater fever. (05 Mar 2000) |
| lepra cells | Distinctive, large, mononuclear phagocytes (macrophages) with a foamlike cytoplasm, and also poorly staining saclike structures resulting from degeneration of such cell's, observed characteristically in leprous inflammatory reactions; indistinct staining results from numerous, fairly closely packed leprosy bacilli, which are acid-fast and resistant to staining by ordinary methods but may be vividly demonstrated by acid-fast staining procedures. (05 Mar 2000) |
| fusiform cells of cerebral cortex | Spindle-shaped cell's in the sixth layer of the cerebral cortex. (05 Mar 2000) |
| leydig cells | Cells in the interstitial tissue of the testis that are believed to furnish the internal secretion of that gland. (12 Dec 1998) |
| Leydig's cells | lutropin |
| light cells of thyroid | 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) |
| llc-pk1 cells | Renal epithelial cell line originally derived from porcine kidneys. It is used for pharmacologic and metabolic studies. (12 Dec 1998) |
| lutein cells | The cells of the corpus luteum which are derived from the granulosa cells and the theca cells of the graafian follicle. (12 Dec 1998) |
