Although, the biological functions of Hela cells might not be the same as those of normal cells, Hela cells are still a promising cell line for evaluation. In addition, Hela cells are a cloned cell line and can easily grow in large quantities. Thisepithelial cell assay system may be a very useful tool for evaluating more environmental chemicals for their mutagenic effects on the respiratory tract. Furthermore, there is a need for further studies of this technique to examine the questions of how good a predictor of carcinogenicity it is.en-USMUTAGENHELA CELLENVIRONMENTjournal article
