A human squamous carcinoma cell line, PWH-S1, has been established from the metastatic lymph node of a Chinese patient with a squamous cell carcinoma of the tongue. The fibroblast-free culture has been propagated in DMEM supplemented with 10% fetal bovine serum for more than 100 passages. PWH-S1 cells showed anchorage-independent growth in 0.3% agar solution. PWH-S1 cell line exhibited a monolayer growth and loss of contact inhibition. The in vitro doubling time of the PWH-S1 cell line was approximately 28 h. PWH-S1 was tumourigenic after inoculation into nude mice. Karyotype analysis showed the chromosome abnormality with a modal number of 69. Electron microscopy demonstrated poorly differentiated neoplastic cells with some features of squamous cell differentiation. No human papillomavirus (type 6, 11, 16, 18, 31) was detected in the PWH-S1 cell line by the polymerase chain reaction.
