Cristiane Miranda França, D.D.S., M.S., Ph.D., a research assistant professor of restorative dentistry in the OHSU School of Dentistry, and colleagues created two models to simulate large and small blood capillaries. She demonstrates this process by creating a reaction through a slide with engineered blood capillaries. (OHSU/Christine Torres Hicks)
