title: [The immunohistochemical detection in the human placenta of proteins related to the blood coagulation system].
abstract: Distribution in mature human placenta of plasminogen, pregnancy-associated inhibitors of proteases (pregnancy-associated protein A (PAPP-A) and alpha 2--pregnancy-associated glycoprotein, and also of not associated with pregnancy alpha 2-macroglobulin and alpha 1-antitrypsin was examined. Primary monospecific antibodies and secondary antibodies labeled with colloid gold were used. Plasminogen was detected in the fetal and maternal blood, and also on the surface of some placental villi (as thin positively stained rims). Pregnancy-associated protease inhibitors were detected in the syncytium of the villi of all histological types and also in the fetal and maternal blood. Staining for alpha 2-macroglobulin was most intensive. This antigen was detected in the maternal and fetal blood and on the surface of the villi. alpha 2-antitrypsin was detected in the fetal and maternal blood. It has been shown that both free plasminogen and its inhibitors are retained on the surface of the placental villi.
