Karyotype
|
modal number = 71; range = 65 to 75.
This is a near triploid human cell line. The modal chromosome number was 71 although cells with 70 chromosomes occurred frequently. The frequency of higher ploidies was 2.9%.; Over 11 marker chromosomes were common to all cells, and at least 6 others were found in some cells. Among the common markers were: del(1)(p22), i(3q), i(6p), i(7p), t(7p17q), 14q+ and five others.; Of these, del(1) and i(7p) were generally double [occasionally triple for del(1)]. Constantly, there were 2 to 3 minute chromosomes that were about 1/2 the size of a G group chromosome.; Structurally normal N17 had only a single copy per cell, whereas N15 had four copies and N20 and N21 had four or more copies. The X chromosome was paired, but the Y was not found by fluorescence microscopy.

Derivation
|
The NCI-H596 cell line was derived by A.F. Gazdar and H. Oie in 1983 from a tumor mass in the chest wall of a patient with adenosquamous carcinoma of the lung. The specimen was obtained prior to therapy.

Comments
|
The cells express easily detectable levels of p53 mRNA (comparable to levels found in normal lung), and exhibit no gross structural DNA abnormalities. The cells stain positively for keratin and vimentin, but are negative for neurofilament triplet protein. The cells express multiple markers of squamous differentiation, including cross linked envelope formation, transglutaminase activity and production of involucrin.
