title: Antagonistic effect of cocultivation on mitomycin C-induced aberration rate in cells of a patient with Fanconi's anemia and in Chinese hamster ovary cells.
abstract: The rate of spontaneous chromosomal aberrations in fibroblasts of a patient with Fanconi's anemia was slightly reduced after cocultivation with Chinese hamster ovary (CHO) cells. However, after mitomycin C treatment, a significant reduction of induced chromosomal damage was found in the FA cells while a significant increase was observed in the CHO cells. This antagonistic effect could be attributed to some diffusible agent(s). The results are discussed with respect to the underlying mechanism of the disease.
