Abstract
We have introduced human mini-chromosomes of 4 Mb and approximately 15 Mb in size into mouse embryonal stem cells. Although these human mini-chromosomes are stable in hamster and chicken cells, they re-arrange or segregate aberrantly in the embryonal stem cells and are rapidly lost in the absence of selection. However, one of the mini-chromosomes re-arranged, acquired mouse centromeric sequences and was then stably maintained for at least 60 population doublings in culture. This mini-chromosome, which is 4 Mb in size, is a candidate for a mouse germ line chromosome vector.Entities:
