CA125 is released by human amnion cells in culture
No full textCA 125 was measured in the medium of human amnion cells in primary culture after confluence. The antigen accumulated as a function of time with a median value of 1897 U/mg protein after 7 days in culture. CA 125 was detectable by immunoperoxidase staining in the cells, which supports the possibility that amnion cells play a role as a source of the CA 125 found in the amniotic flui

No full textCA 125 antigen was measured in amniotic fluid, maternal blood, cord blood, and fetal urine by a commercially available immunoradiometric assay kit. The amniotic fluid was obtained from 99 normal pregnancies at various gestational ages. The mean antigen levels were 29,676, 3350, and 1680 U/ml in amniotic fluid of the first, second, and third trimesters, respectively. In maternal blood, 12.5% of pregnant women in the first trimester of pregnancy showed elevated levels of CA 125 (65 to 100 U/ml). Late in gestation, CA 125 levels in cord blood and fetal urine were always less than 65 U/ml. Immunohistochemical study of CA 125 in fetal membranes, placenta, and decidua showed the presence of antigen only in the amnion. These results suggest that CA 125 is shed into amniotic fluid directly from the amniotic membrane
