Abstract
A method that allows the performance of double-colour chromosome painting (FISH) on previously G-banded human sperm metaphases has been developed. Sperm chromosomes were obtained by using the fusion technique between zona-free hamster oocytes and human spermatozoa. Single- and double-colour chromosome painting was performed using DNA libraries specific for chromosomes X, Y and 21 on either unstained or G-banded preparations. The hybridization efficiency was very high (98%). The sequential staining technique is very useful for analyses of structural (stable) and numerical chromosome aberrations in human sperm and thus can increase the efficiency of the human sperm-hamster oocytes fusion system to assess the risk to human germ cells as a result of endogenous and exogenous factors.Entities:
