Quantitative evaluation of fluorescence in situ hybridization (FISH) signals in uncultured coelomic cells

Abstract

Uncultured coelomic cells were hybridized with alpha satellite DNA probes representing chromosomes X, Y, 18, and 13/21 in order to evaluate the distribution of hybridization signals obtained by fluorescence in situ-hybridization (FISH) analysis of this cell type. Cells from 26 samples were hybridized with the X probe and the Y probe was hybridized with cells from 25 of the samples. Cells from 16 and 11 samples were hybridized with an 18 alpha satellite DNA probe and 13/21 alpha satellite probe, respectively. The evaluation demonstrated that FISH with X, Y, 18, and 13/21 alpha satellite DNA probes on uncultured coelomic cells is a reliable technique since the distribution of hybridization signals is comparable to that seen in uncultured amniotic fluid cells.
