ScienceDaily (Nov. 27, 2009) Dr. Bernard Thיbaud lives in two very different worlds. As a specialist in the Stollery Children's Hospital's Neonatal Intensive Care Unit at the Royal Alexandra Hospital, he cares for tiny babies, many of whom struggle for breath after being born weeks before they are due. Across town, in his laboratory in the Faculty of Medicine & Dentistry at the University of Alberta, Dr. Thיbaud dons a lab coat and peers into a microscope to examine the precise effect of stem cells on the lungs.
