Live Imaging of Fetal Intra-abdominal Organs Using Two-Photon Laser-Scanning Microscopy
The processes by which the intra-abdominal organ circulatory system develops in the embryo and during organogenesis are unclear. Previous studies have used fixed tissues to study the development of abdominal organ vasculature in the embryo; however, the intravital circulation of intra-abdominal organs in rodent fetal development has not been studied. This protocol describes a system that uses two-photon laser-scanning microscopy (TPLSM) for real-time observation and quantification of normal and pathologic live fetal intra-abdominal dynamics while the fetus is still connected to the mother via the umbilical cord.
