| juxtaglomerular cells | Cell's, located at the vascular pole of the renal corpuscle that secrete renin and form a component of the juxtaglomerular complex; they are modified smooth muscle cell's primarily of the afferent arteriole of the renal glomerulus. Synonym: Goormaghtigh's cells. (05 Mar 2000) |

| Tzanck cells | Acantholytic epithelial cell's seen in the Tzanck test. (05 Mar 2000) |
| kB-cells | A cell line derived from a human carcinoma of the nasopharynx, used as an assay for antineoplastic agent. (12 Dec 1998) |
| K cells | Lymphocyte-like effector cells which mediate antibody-dependent cell cytotoxicity. They kill antibody-coated target cells which they bind with their fc receptors. (12 Dec 1998) |
| yolk cells | Primitive embryonic cell's lying between the endoderm and mesoderm; they probably give rise to the endothelium of vitelline vessels. (05 Mar 2000) |
| killer cells | Lymphocyte-like effector cells which mediate antibody-dependent cell cytotoxicity. They kill antibody-coated target cells which they bind with their fc receptors. (12 Dec 1998) |
| killer cells, lymphokine-activated | Cytolytic lymphocytes with the unique capacity of killing natural killer (nk)-resistant fresh tumour cells. They are interleukin-2-activated nk cells that have no MHC (major histocompatibility complex) restriction or need for antigen stimulation. Lak cells are used for adoptive immunotherapy in cancer patients. (12 Dec 1998) |
| killer cells, natural | Cells responsible for spontaneous cytotoxicity of a variety of tumour cells without prior immunization. These natural killer cells are found in non-immune humans and experimental animals and are thought by some to be the same as killer cells (killing by antibody-dependent cell cytotoxicity), but they can also kill in the absence of antibody. (12 Dec 1998) |
| Kulchitsky cells | Cell's with granules that may be either argentaffinic or argyrophilic; the cell's, scattered throughout the digestive tract, are of several varieties and are believed to produce at least 20 different gastrointestinal hormones and neurotransmitters. Synonym: enterochromaffin cells, Kulchitsky cells. (05 Mar 2000) |
| kupffer cells | Large star-shaped or pyramidal cells with a large oval nucleus and a small prominent nucleolus. These intensely phagocytic cells line the walls of the sinusoids of the liver and form a part of the reticuloendothelial system. (12 Dec 1998) |
| labyrinth supporting cells | Cells forming a framework supporting the organ of corti. Specific cells are those of claudius, deiters and hensen. (12 Dec 1998) |
| foam cells | Lipid-laden macrophages originating from monocytes or from smooth muscle cells. (12 Dec 1998) |
| 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) |
