| HDRBC | head-damaged red blood cells |

| HEI | Health Effects Institute; high-energy intermediate; homogenous enzyme immunoassay; human embryonic i... |
| HeLa | Helen Lake [human cervical carcinoma cells] |
| HEp-1 | human cervical carcinoma cells |
| HEp-2 | human laryngeal tumor cells |
| schwann cells | Neuroglial cells of the peripheral nervous system which form the insulating myelin sheaths of peripheral axons. (12 Dec 1998) |
|---|---|
| hilus cells | Cell's in the hilus of the ovary that produce androgens; they are thought to be the ovarian counterpart of the interstitial cell's of the testis. Synonym: Berger cells. (05 Mar 2000) |
| hobnail cells | Cell's characteristic of a mesonephroma; a round expansion of clear cytoplasm projects into the lumen of neoplastic tubules, but the basal part of the cell containing the nucleus is narrow. (05 Mar 2000) |
| horizontal cells of retina | Cell's in the outer part of the inner nuclear layer of the retina that lie with their axes more or less parallel with the surface. They are thought to connect the rods of one part of the retina with cones of another part. (05 Mar 2000) |
| Purkinje's cells | <neurology, pathology> A class of output neurons in the cerebellum, which are the only neurons that convey signals away from the cerebellum. They form a layer of large ganglion cells near the surface of the cerebellum. Origin: From J. E. Purkinje, their discoverer. (12 Dec 1998) |
| Hortega 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) |
| pyramidal cells | Projection neurons in the cerebral cortex and the hippocampus. Pyramidal cells have a pyramid-shaped soma with the apex and an apical dendrite pointed toward the pial surface and other dendrites and an axon emerging from the base. The axons may have local collaterals but also project outside their cortical region. (12 Dec 1998) |
| seromucous cells | Glandular cell's intermediate in histologic characteristics between serous and mucous cell's. Synonym: mucoalbuminous cells, seromucous cells. (05 Mar 2000) |
| sertoli cells | Elongated cells in the tubules of the testis to which the spermatids become attached. They provide support, protection, and, apparently, nutrition until the spermatids become transformed into mature spermatozoa. (12 Dec 1998) |
| Sertoli's 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) |
| shadow cells | Immature leukocytes of any type that have undergone partial breakdown during preparation of a stained smear or tissue section, because of their greater fragility; smudge cell's are seen in largest numbers in chronic lymphocytic leukaemia. Synonym: basket cell, Gumprecht's shadows, shadow cells. (05 Mar 2000) |
| signet ring cells | Altered basophilic cells of the anterior lobe of the pituitary that develop following castration; the body of the cell is occupied by a large vacuole that displaces the nucleus to the periphery, giving the cell a resemblance to a signet ring. Synonym: signet ring cells. (05 Mar 2000) |
| smudge cells | Immature leukocytes of any type that have undergone partial breakdown during preparation of a stained smear or tissue section, because of their greater fragility; smudge cell's are seen in largest numbers in chronic lymphocytic leukaemia. Synonym: basket cell, Gumprecht's shadows, shadow cells. (05 Mar 2000) |
| somatic cells | Cells of an animal or plant other than the reproductive cells. (14 Nov 1997) |
| splenic cells | Large round ameboid cell's (macrophages) in the splenic pulp. (05 Mar 2000) |
