 value was 0.00 (range 0.00-0.000). The SF0 of the most sensitive diploid mesothelioma cell line was 0.00: Less than that of the foetal fibroblast cell line (0.00). The survival fractions (0.00 and 0.00) of the two most resistant cell lines, which also were aneuploid, were equal to that of the HeLa cell line (0.00). The
