The thyroid hormones, thyroxine (T4) and triiodothyronine (T3), are essential for normal growth and development of the fetus. Their bioavailability in utero depends on development of the fetal hypothalamic-pituitary-thyroid gland axis and the abundance of thyroid hormone transporters and deiodinases that influence tissue levels of bioactive hormone. Fetal T4 and T3 concentrations are also affec...
Recent clinical studies indicate that thyroid hormone plays essential roles in fetal brain development. However, the mechanism by which thyroid hormone affects fetal brain development is poorly studied. We recently identified several genes expressed in the fetal cortex whose abundance is affected by thyroid hormone of maternal origin. However, it is unclear whether these genes are directly regu...
BACKGROUND We have investigated the usefulness of a model of cardiac development in a large mammal, sheep, for studies of engraftment of human stem cells in the heart. METHODS AND RESULTS Adult and fetal human mesenchymal stem cells were injected intraperitoneally into sheep fetuses in utero. Hearts at late fetal development were analyzed for engraftment of human cells. The majority of the en...
During pregnancy, mother's well-being affects directly the newborn development. Some maternal and placental complications, such as gestational diabetes, preeclampsia (PE), preterm delivery and intrauterine growth restriction (IUGR), may contribute to fetal growth deviations or fetal development modifications. Usually the newborn weight correlates positively with placenta weight, showing the int...
Objective(s): Oleate can be produced through de novo synthesis, which contributes to biological processes and signaling pathways. However, the role of this non-essential fatty acid in hepatic development remains unclear. The current study aimed to evaluate the influence of early oleate deficiency induced by the inhibitor of de novo oleate synthesis MF-438 on fetal rat ...
Epigenetic modifications have proven to play a significant role in cancer development, as well as fetal development. Taking advantage of the knowledge acquired during the last decade, great interest has been shown worldwide in deciphering the fetal epigenome towards the development of methylation-based non-invasive prenatal tests (NIPT). In this review, we highlight the different approaches imp...
