Models of endocrine disrupting effects: Human placental steroidogenesis.
Abstract
Abstract Endocrine disruption during pregnancy has gained increasing
interest as epidemiological studies report associations of exposures and
adverse effects on fetal growth, followed by effects on the growing
child and ultimately in the adult. When studying endocrine disruption
during pregnancy the placental steroidogenesis is difficult to model, as
the human placenta is unique in the pathway of cellular uptake of
cholesterol, the high levels of progesterone production, and the
expression of aromatase. Models to test for endocrine disruption should
respect species differences with preference to human models for human
risk assessment. Here, we present existing research of placental
steroidogenesis and other placental hormones using human placental
models: Placental perfusion, placental explants, microsomes and
vesicles, primary cell culture, stem cells, Placenta-on-a-chip, and
choriocarcinoma cell cultures: BeWo, HTR8/SVneo, Jar, JEG-3 and ACH-3P.
We conclude that there is a lack of research focused on placental
steroidogenesis and the effects of EDC. Advantages and limitations of
existing models are discussed and future directions suggested.
