[Establishment and characterization of a new human germ cell tumor strain (NOC-Ts) in culture].
We have derived and characterized a new cell line from a teratoma with a embryonal carcinoma and seminoma. The medium used for the cell culture was Eagle's MEM synthetic culture medium (Gibco Inc.) supplemented with 10% new calf serum (Tissue plus, Mitsubishi Kasei Co.). Subcultures were performed on 3 to 4 days basis at 1:2 split by the use of 0.25% trypsin solution. The morphology of obtained cells was a epithelial-like shape and the cell grew in a monolayered sheet with about 30-32 hrs of population doubling time. The model chromosome number of this cell line was 73 including one large submetacentric marker chromosome. The temperature sensitivity and the tumorigenicity of this cell were tested in this experiment.
