Chorioamnionitis is an intrauterine infection of the placenta and fetal membranes. It is the leading cause of preterm delivery and is a common risk factor for adverse pulmonary outcomes such as bronchopulmonary dysplasia. There is evidence to suggest that the first negative impacts on pulmonary development occur in utero in the presence of chorioamnionitis. In this episode, we meet assistant professors Niki Reynaert and Tim Wolfs from Maastricht University in the Netherlands. Together they studied an ovine model of chorioamnionitis in order to study the effects of chronic and acute inflammation on the developing lungs.
