Cell type-dependent difference in the distribution and frequency of aphidicolin-induced fragile sites: T and B
1Department of Pediatrics, Yamaguchi University School of Medicine, Japan.
The distribution and frequency of aphidicolin-induced common fragile sites were studied in Epstein-Barr virus-transformed B lymphocytes from eight normal individuals, and in bone marrow cells from six children in remission from malignant blood diseases. PHA-stimulated helper T lymphocytes from the same individuals were also studied. These cells were cultured in MEM, and treated with 0.2 microM aphidicolin for 26 h. The results, together with those of our previous study on cultured skin fibroblasts, indicated that the distribution and frequency of aphidicolin-induced fragile sites are different among different types of cells.
