Karyotype
|
hypotriploid; modal number = 54; range = 46 to 57. Twenty to 25 marker chromosomes were common to all cells. These included t(13q21q), der(1)t(1;21)(p36.1;q11), der(7)t(7;7)(p22;q22), 11p+, 12p+, and 15p+. Neither DM nor HSR were detected; structurally normal N1, N2, N13 and N21 were absent. Generally, there were 3 copies of both F group chromosomes; the X chromosomes were paired, and structurally normal Y chromosome was not found.

Derivation
|
The NCI-H510A cell line was derived by D. Carney, A.F. Gazdar and associates in 1982 from an adrenal metastasis in an adult male patient.

Comments
|
The cells produce easily detectable p53 mRNA at levels comparable to those in normal lung tissue.
The line does not exhibit any gross structural DNA abnormalities.
The cells express elevated levels of four biochemical markers of SCLC: neuron specific enolase, the brain isoenzyme of creatine kinase, L-DOPA decarboxylase and bombesin-like immunoreactivity.
The cells form transplantable tumors with typical small cell carcinoma histology.
