Murine tracheal epithelial cell lines, TM01 and TM02-3, were established from a primary culture of tracheal cells of adult transgenic mice bearing a temperature-sensitive simian virus (SV40) large T-antigen gene. Both TM01 and TM02-3 cells, which grew until confluent monolayers were formed, maintained tight contact with neighboring cells, and retained the characteristics of epithelial cells with microvilli on the surface. These cells grew at a permissive temperature (33 degrees C), but did not at a nonpermissive temperature (39 degrees C), indicating that TM01 and TM02-3 cells undergo temperature-sensitive growth. Large T-antigen was expressed only in the nuclei at 33 degrees C. Sepharose CL-4B column chromatography using a 14C-glucosamine hydrochloride, indicating that both cells produced high molecular weight glycoconjugates, and suggesting that these cells may originate from mucus-producing cells. TM01 cells expressed intercellular adhesion molecular-1 (ICAM-1) in both unstimulated and stimulated (1,000 U/ml tumor necrosis factor-alpha and 500 U/ml interferon-gamma) conditions, whereas TM02-3 cells expressed ICAM-1 only under stimulated conditions. We conclude that these cell lines may serve as a useful model to study the tracheal cell functions under defined in vitro conditions.

D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D002250 Carbon Radioisotopes Unstable isotopes of carbon that decay or disintegrate emitting radiation. C atoms with atomic weights 10, 11, and 14-16 are radioactive carbon isotopes. Radioisotopes, Carbon
D002472 Cell Transformation, Viral An inheritable change in cells manifested by changes in cell division and growth and alterations in cell surface properties. It is induced by infection with a transforming virus. Transformation, Viral Cell,Viral Cell Transformation,Cell Transformations, Viral,Transformations, Viral Cell,Viral Cell Transformations
D002478 Cells, Cultured Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others. Cultured Cells,Cell, Cultured,Cultured Cell

D004847 Epithelial Cells Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.
