| G0 | quiescent phase of cells leaving the mitotic cycle |
| G1 | presynthetic gap [phase of cells prior to DNA synthesis] |
| G2 | postsynthetic gap [phase of cells following DNA synthesis] |
| cytomegalic cells | Cell's containing large intranuclear and intracytoplasmic cytomegalic inclusion bodies caused by cytomegalovirus; a member of the family Herpesviridae. (05 Mar 2000) |
|---|---|
| cytotrophoblastic cells | Stem cell's that fuse to form the overlying syncytiotrophoblast of placental villi. Synonym: Langhans' cells. (05 Mar 2000) |
| heart failure cells | Macrophages in the lung during left heart failure that often carry large amounts of haemosiderin. See: siderophore. (05 Mar 2000) |
| prokaryotic cells | Cells, such as those of bacteria and the blue green algae, which lack a nuclear membrane so that the nuclear material is either scattered in the cytoplasm or collected in a nucleoid region. (12 Dec 1998) |
| HEMPAS cells | The abnormal erythrocytes of type II congenital dyserythropoietic anaemia. See: HEMPAS. (05 Mar 2000) |
| satellite cells | Neuroglial cell's surrounding the cell body of a ganglion cell in the spinal, cranial, and autonomic ganglia. (05 Mar 2000) |
| Schultze's cells | Very slender nerve cell's, with large nuclei and surmounted by six to eight long, sensitive cilia in the olfactory epithelium at the roof of the nose; they are the receptors for smell. Synonym: olfactory cells, Schultze's cells. (05 Mar 2000) |
| 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) |
