Researchers engineer 'protein switch' to dissect role of cancer's key players

Researchers at the University of North Carolina at Chapel Hill School of Medicine have 'rationally rewired' some of the cell's smallest components to create proteins that can be switched on or off by command. These 'protein switches' can be used to interrogate the inner workings of each cell, helping scientists uncover the molecular mechanisms of human health and disease.

Adult stem cells isolated from human intestinal tissue

The accomplishment provides a much-needed resource for scientists eager to uncover the true mechanisms of human stem cell biology. It also enables them to explore new tactics to treat inflammatory bowel disease or to ameliorate the side effects of chemotherapy and radiation, which often damage the gut.
