The purpose of this report was the initiation and further maintenance of tumor cells from a primary larynx squamous cell carcinoma. A tumor fragment was mechanically dissociated, the cells were grown in RPMI medium, being the primary culture dependent on the presence of epidermal growth factor and insulin; during subsequent passages the adaptation to conventional growth conditions was obtained. Cells grew in monolayer with an epitheliod shape, showing a pavement-like arrangement; at confluence, cells piled up without contact inhibition maintaining the same morphology. Population doubling time was about 48 h with a colony-forming efficiency of 10%. Immunocytochemical characterization was performed with a panel of monoclonal antibodies reactive against tumor associated antigens, including mucin glycoproteins and related carbohydrate antigens, carcinoembryonic antigen (CEA), p53 as well as cytokeratins, vimentin and desmin. T201 expressed CEA, sialyl Lewis x, Lewis x, Lewis y, MUC1 mucin, Tn hapten, p53, vimentin and cytokeratins. On the other hand, a modal chromosome diploid number of 46 occurring in 74% of cells was detected. Present data confirmed that the methodology employed was adequate for the establishment and characterization of a new cell line which can provide a useful model to study biological and immunological aspects of larynx squamous cell carcinoma.
