Biogenic polyamines interacting with pregnancy serum elicit potent suppression of lymphocyte transformation in vitro. Within the assay limits, activity was first shown after about 15 weeks' gestation and reached its highest level at about 28 weeks. This level was maintained until term. It is thought that specific humoral amine oxidases were the cause. Fetal-cord serum and non-pregnancy serum were inactive. This system may have an immunoregulatory function in pregnancy.

Two-way mixed lymphocyte reactivity (2-way-MLR) between maternal and fetal lymphocytes in vitro, and one-way mixed lymphocyte reactivity (1-way-MLR) of maternal lymphocytes (responders) to stimulation by mitomycin-treated fetal lymphocytes (stimulators), were investigated in normal and pre-eclamptic pregnancies. No relationship was observed between pre-eclampsia and the 2-way-MLR. The 1-way-MLR was lowest in normal pregnancy, higher in mild pre-eclampsia, and highest in severe pre-eclampsia, although none of these differences were statistically significant.

There was no significant difference between the mean spontaneous transformation rates of maternal lymphocytes from normal pregnant women and patients with pre-eclampsia.
