Potential genetic cause of congenital defect colonic atresia

In a finding that helps resolve a long-standing question in developmental biology, Klaus H. Kaestner, PhD, Professor of Genetics, and colleagues report in the journal Developmental Cell this week about how the mammalian gut forms. Mice were genetically engineered to lack the protein Cdx2 in the cells that normally go on to form the stomach and intestine.
