Secretion of cytokines in component cells at the maternal-fetal interface in early human pregnancy.

<p>Primary human first trimester trophoblasts, decidual stromal cells, or decidual immune cells were cultured in 24-well plates for 24, 48, or 72 h. The supernatants were harvested and subjected to a cytokine ELISA assay. Data represent the mean ± SE of three independent experiments with a total of 17 villi and three deciduas, performed in triplicate wells with three different samples.
