In vitro prostaglandin biosynthesis in human pregnant uterus from arachidonic acid.
Formation of prostaglandins (F2alpha, E2 and D2) in the pregnant human uterus microsomes was studied using 14C-labeled arachidonic acid. Sample of uterine pieces were removed from the lower uterine segment at the time of Caesarean section. The prostaglandin synthesis in the microsomal fraction was characterized in terms of cofactors, substrate concentration and incubation time requirements.
