After an injury, the body grows new blood vessels to repair damaged tissue. But sometimes too much growth causes problems, as when new blood vessels in the eyes leak, causing diabetic retinopathy and blindness if not treated.A protein called CIB1, discovered by researchers at the University of North Carolina at Chapel Hill School of Medicine, appears to play a major role in controlling new blood vessel growth, offering a target for drug treatments to help the body repair itself after injury and control unwanted blood vessel growth.
