| Sternberg cells | Large cells of unknown origin, usually multinucleate, whose presence is the common histologic characteristic of hodgkin disease. (12 Dec 1998) |

| Sternberg-Reed cells | Large cells of unknown origin, usually multinucleate, whose presence is the common histologic characteristic of hodgkin disease. (12 Dec 1998) |
| Neumann's cells | Nucleated cell's in the bone marrow developing into red blood cell's. (05 Mar 2000) |
| neurilemma cells | Neuroglial cells of the peripheral nervous system which form the insulating myelin sheaths of peripheral axons. (12 Dec 1998) |
| neuroepithelial cells | neuroectoderm |
| neuroglia cells | See: neuroglia. (05 Mar 2000) |
| neurolemma cells | Neuroglial cells of the peripheral nervous system which form the insulating myelin sheaths of peripheral axons. (12 Dec 1998) |
| neurosecretory cells | Nerve cell's, such as those of the hypothalamus, that elaborate a chemical substance (such as a releasing factor, neuropeptide, or, more rarely, a true hormone) that influences the activity of another structure (e.g., anterior lobe of the hypophysis). See also neurosecretion. (05 Mar 2000) |
| stromal cells | Connective tissue cells of an organ found in the loose connective tissue. These are most often associated with the uterine mucosa and the ovary as well as the haematopoietic system and elsewhere. (12 Dec 1998) |
| NK cells | Large granular lymphocytes which do not express markers of either T or B-cell lineage. These cells do possess Fc receptors for IgG and can kill target cells using antibody-dependent cell-mediated cytotoxicity. NK cells can also use perforin to kill cells in the absence of antibody. Killing may occur without previous sensitization. Synonym: NK cells. (05 Mar 2000) |
| null cells | Large granular lymphocytes that lack surface markers/membrane associated proteins of either B or T lymphocytes. (05 Mar 2000) |
| nurse cells | Elongated cell's in the seminiferous tubules to which spermatids are attached during spermiogenesis; they secrete androgen-binding protein and establish the blood-testis barrier by forming tight junctions with adjacent Sertoli's cell's. Synonym: nurse cells. (05 Mar 2000) |
| Davidoff's 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) |
| d cells | Cells found throughout the gastrointestinal tract and in the pancreas. They secrete somatostatin in both an endocrine and paracrine manner. Somatostatin inhibits gastrin, cholecystokinin, insulin, glucagon, pancreatic enzymes, and gastric hydrochloric acid. A variety of substances which inhibit gastric acid secretion (vasoactive intestinal peptide, calcitonin gene-related peptide, cholecystokinin, beta-adrenergic agonists, and gastric inhibitory peptide) are thought to act by releasing somatostatin. (12 Dec 1998) |
| decoy cells | Benign exfoliated epithelial cell's with pyknotic nuclei seen in urinary infections; may be mistaken for malignant cell's. (05 Mar 2000) |
