ES cells often aquire a chromosome 8 trisomy which interferes with their ability to pass through the germ line of chimeric mice. For details see: Liu, X., H. Wu, et al. (1997). "Trisomy eight in ES cells is a common potential problem in gene targeting and interferes with germ line transmission." Dev Dyn 209(1): 85-91
