Adult stem cells play pivotal roles in self-renewing tissues but also in the post-injury repair of adult organs that normally show little proliferative activity. A new study shows that Sox9 marks a putative adult stem cell population that contributes to the self-renewal and repair of the liver, exocrine pancreas and intestine, three organs of endodermal origin.
