title: In vitro methods for studying vascularization of the murine allantois and allantoic union with the chorion.
abstract: Despite the importance of the definitive chorio-allantoic placenta in fetal survival, fetal development, and long-term health of the adult, little is known about how the placenta's individual components, the allantois and the chorion, proliferate and develop. In this chapter, two techniques will be described: (1) explanting murine allantoises for culture in isolation, and (2) grafting murine allantoises into living whole mouse embryos. Together, these will enable study of differentiation of allantoic mesoderm into the umbilical vasculature, and the mechanism(s) by which the allantois unites with the chorion to form the chorio-allantoic placenta.
