| RTG-2 | rainbow trout gonadal tissue cells |
| enteroendocrine 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) |

| entodermal cells | Embryonic cell's forming the yolk sac and giving rise to the epithelium of the alimentary and respiratory tracts and to the parenchyma of associated glands. Synonym: entodermal cells. (05 Mar 2000) |
| epithelial cells | Cells that cover the surface of the body and line its cavities. (12 Dec 1998) |
| epithelioid cells | Characteristic cells of granulomatous hypersensitivity. They appear as large, flattened cells with increased endoplasmic reticulum. They are believed to be activated macrophages that have differentiated as a result of prolonged antigenic stimulation. Further differentiation or fusion of epithelioid cells is thought to produce multinucleated giant cells (giant cells). (12 Dec 1998) |
| erythroid progenitor cells | Committed, erythroid stem cells derived from myeloid stem cells. The progenitor cells develop in two phases: erythroid burst-forming units (bfu-e) followed by erythroid colony-forming units (cfu-e). Bfu-e differentiate into cfu-e on stimulation by erythropoietin, and then further differentiate into erythroblasts when stimulated by other factors. (12 Dec 1998) |
| tubal air cells | Occasional small air cells in the inferior wall of the auditory tube, near the tympanic orifice, communicating with the tympanic cavity. Synonym: cellulae pneumaticae tubae auditivae, air cells of auditory tube. (05 Mar 2000) |
| ethmoid air cells | The numerous small air-filled cells of the ethmoidal labyrinth. See: anterior ethmoidal air cells, middle ethmoidal air cells, posterior ethmoidal air cells. Synonym: cellulae ethmoidales, sinus ethmoidales, ethmoidal cells. (05 Mar 2000) |
| ethmoidal cells | The numerous small air-filled cells of the ethmoidal labyrinth. See: anterior ethmoidal air cells, middle ethmoidal air cells, posterior ethmoidal air cells. Synonym: cellulae ethmoidales, sinus ethmoidales, ethmoidal cells. (05 Mar 2000) |
| tumour stem cells | <cell biology> Colony-forming cells which give rise to neoplasms. (12 Dec 1998) |
| eukaryotic cells | Cells of the higher organisms, containing a true nucleus bounded by a nuclear membrane. (12 Dec 1998) |
| tunnel cells | Cell's forming the outer and inner walls of the tunnel in the organ of Corti. Synonym: Corti's pillars, Corti's rods, pillar cells of Corti, tunnel cells. (05 Mar 2000) |
| tympanic air cells | Numerous groovelike depressions in the walls of the tympanic cavity, communicating with the tubal air cells. Synonym: cellulae tympanicae, tympanic cells. (05 Mar 2000) |
| tympanic cells | Numerous groovelike depressions in the walls of the tympanic cavity, communicating with the tubal air cells. Synonym: cellulae tympanicae, tympanic cells. (05 Mar 2000) |
| type I cells | Highly attentuated squamous cell's that form the gas-permeable epithelium lining the alveoli of the lungs. Synonym: type I cells. (05 Mar 2000) |
| type II cells | Cuboidal cell's connected with the squamous pulmonary alveolar cell's and having in their cytoplasm lamellated bodies (cytosomes) that represent the source of the surfactant that coats the alveoli. Synonym: granular pneumonocytes, type II cells. (05 Mar 2000) |
