Thursday, March 4, 2010 - 05:56 in Health & Medicine

Today, during the 39th Annual Meeting of the American Association for Dental Research, convening at the Walter E. Washington Convention Center in Washington, DC, lead researcher C. Millan (U.S. Army Dental Corps, Martinez, Georgia) will present a poster of a study titled "A Novel In Vitro Model for Light-Induced Wound Healing." Studies have suggested that exposure to minimal doses of blue-violet light (400-500 nm) elicits production of small amounts of reactive oxygen species (ROS), and contributes to increased mitochondrial activity and cell growth in epithelial cells. Many growth factor signaling pathways generate ROS.
