Adult stem cells represent a sort of blank clay from which a myriad of different cell and tissue types are molded and as such are of critical importance to health, ageing and disease.  In tissues that turn over rapidly, such as the intestines, the self-renewing nature of stem cells and their susceptibility to cancer-causing mutations has led researchers to postulate that
