Transformation of human osteosarcoma cells by a chemical carcinogen

A human osteosarcoma clonal cell line (TE-85, clone F-5) was treated in vitro with various levels of 7,12-dimethylbenz[a]anthracene or dimethyl sulfoxide (control). Cells treated only with the carcinogen underwent morphologic alteration in vitro, and one of these altered cell lines produced tumors subcutaneously and intracerebrally when injected into NIH nude mice.
