The malignant transformation of human embryo lung fibroblast (HELF) induced by CdCl2 was tested by 3H-TdR incorporation, chromosome analysis and flow cytometry. Chromosome aberration, the ratio of cells in different cell cycle phases and the quantities of DNA synthesis of different groups were determined. The results showed that the morphology of HELF changed in three levels of cadmium chloride (I 0.004 mumol/L, II 0.02 mumol/L and III 0.04 mumol/L) treated for three times. The cell growth was disordered and overlapping without density regulating effect and the transforming foci were formed. The quantities of chromosome were decreased or increased and the dicentric and acentric fragments were found in experimental groups. The ratio of cells in S phase increased and the quantities of DNA synthesis in experimental groups were 2.4-3.8 times higher than that of negative control group. The chromosome aberration of cells, the increase of cells in S phase and the increase of DNA synthesis may play some roles in the malignant transformation of HELF induced by CdCl2.
