Summary: | Here we summarize the recent progress in research on the role of the fibrinolytic system in reproduction, with a special emphasis on the role of the plasminogen activator inhibitors in fetal development. Trophoblasts produce fibrinolytic proteins that can promote normal implantation and regulate blood flow to the fetus and placenta throughout pregnancy. Normal pregnancy is associated with a hypofibrinolytic state that is fundamentally caused by an increase in plasminogen activator inhibitors types 1 and 2. In pre-eclampsia, a fibrinolytic failure, resulting from an increase in plasma and placental concentrations of plasminogen activator inhibitor-1, was observed. The localized elevated concentrations of placenta plasminogen activator inhibitor-1 protein and mRNA observed in pre-eclamptic patients would be expected to foster the deposition of fibrin and thus play a role in the complications associated with this disease. The decreased plasminogen activator inhibitor-2 concentrations in placenta and plasma from intrauterine fetal growth retardation pregnancies and the positive correlation between plasma/placenta plasminogen activator inhibitor-2 concentration and birthweight suggest that this inhibitor could be considered an adequate marker of placental function. |
