Embryonic stem cells accrue genetic changes
5th Sep 2005, 14:30 GMT
An international team of researchers has discovered that human embryonic stem cell lines accumulate changes in their genetic material over time. The findings do not limit the utility of the cells for some types of research or for some future clinical applications, the researchers say, but stem cell lines will need to be closely monitored for genetic changes and to study these alterations' effects. The researchers' findings appear in the Sept. 4 online edition of Nature Genetics.
