Study finds that up to 20% of embryonic stem cell lines develop genetic abnormalities

A new study published in the journal Nature found that up to 1/5 of embryonic stem cell lines developed abnormalities after a year. This genetic abnormalities make the cells prone to becoming cancerous. This is more evidence pointing to the difficulty in scientists ever being able to safely transfer cells created from embryonic stem cells into human patients on a large scale.
