Scientists have used a brand new technique for examining individual stem cells to uncover dramatic differences in the gene expression levels -- which genes are turned 'up' or 'down'-- between apparently identical 'sister' pairs. The research provides the latest evidence that despite having identical DNA, sister stem cells can display considerable differences in their molecular characteristics.
