During human pregnancy there is a continuous transport of numerous syncytiotrophoblastic cells from the intervillous space of the placenta into the maternal lung. There these cells undergo apoptosis and the fetal nuclear DNA is liberated within the pulmonary capillaries to become cffDNA in the maternal serum. We have examined the sections of lungs of 11 pregnant women (from 8 weeks to term gestation) who had come to the Medical Examiner's Offices after their traumatic demise. We then identified the deported, embolized trophoblastic cells in pulmonary capillaries and attempted to show them to contain hCG immunohistochemically but were unable to do this. We also determined their apoptotic profiles by TUNEL reaction.
