Researchers at the Helen F. Graham Cancer Center of the Christiana Care Health System have dicovered a new marker for the stem cells of the colon. The enzyme is shared by both malignant and normal colonic stem cells and can help in understanding the developement of cancer and how to treat it.

The enzyme (called ALDH1 = Aldehyde dehydrogenase 1) is also one of the markers of leukemia and breast cancers, but it's also specific to coon stem cells. Isolaction and identification of the malignant stem cell is an important step in studying the process of carcinogenesis.
