Reduced umbilical artery prostacyclin formation in complicated pregnancies.

abstract：OBJECTIVE:Placental insufficiency is a primary cause of intrauterine growth restriction (IUGR). In our study, microarray technology was used to identify genes, which may impair placentation resulting in IUGR. STUDY DESIGN:The RNA was isolated from both IUGR term placentas and normal term placentas. Microarray experime...
