Possible culprits in congenital heart defects identified

Mitochondria are the power plants of cells, manufacturing fuel so a cell can perform its many tasks, and also are well known for their role in cell death. School of Medicine researchers and colleagues have shown that mitochondria also orchestrate events that determine a cell’s future, at least in the embryonic mouse heart. The study identifies new potential genetic culprits in the origins of some congenital heart defects. Shown is an image of a normal heart.
