Abstract

The frequency and distribution of aphidicolin (APC)-induced common fragile sites (cfs) were analyzed in human embryonic cells of different origins. Embryonic lung fibroblasts (MRC-5), amniocytes (AMNIO) and embryonic retina cells (HERO790) are as sensitive to the APC-induced clastogenic effect as peripheral lymphocytes, whereas embryonic kidney cells (HEK) seem more resistant to the induction of chromosomal gaps and breaks by the drug. Analysis of the distribution of fragile sites confirmed that the expression of specific APC-induced cfs varies in different cells and that the embryonic cell strains show a greater similarity among themselves than to lymphocytes. In addition, HEK, MRC-5, HERO790 and AMNIO cells show specific APC induction of the cfs at the 1p31.2 chromosomal band, which seems to be a distinctive feature of the embryonic stage of cells.
