Assay for tumor promoting agents

摘要

A composition is tested to determine whether it is a tumor promoter or a complete carcinogen by exposing a stable epithelial cell line to the composition for an incubation time period sufficient to induce morphological changes in the cell line. After the incubation time, the cells are observed by morphology changes induced by the composition, which changes are compared to that caused by a known tumor promoter or a known complete carcinogen.
