The placenta is an essential organ during pregnancy, as it not only provides oxygen and nutrients to the foetus, but also responds to factors such as maternal stress and helps the foetus adapt to its environment. However, the mechanisms by which the placenta adjusts to these stressors and how it influences foetal development remain largely unexplored.

The research team observed that maternal stress may leave epigenetic marks on certain placental genes. Specifically, these marks do not modify the genetic structure, but they do alter its function. The study identified epigenetic changes in genes related to the regulation of cortisol, an essential hormone in the body\u2019s response to stress.

Supporting women from the very first stages of pregnancy<\/strong>

This pilot study, funded by a CIBERSAM Intramural project, involved 45 healthy, first-time pregnant women. During pregnancy, their cortisol levels and depressive symptoms were measured and, after delivery, placentas were analysed. At seven weeks, the neurodevelopment of the babies was assessed using a specialized test (Brazelton\u2019s NBAS).

The research team used an advanced sequencing technique that allows them to look at epigenetic changes in large areas of DNA and thus gain a very detailed view of the placental response to maternal stress. This method identified changes in key genes involved in cortisol regulation, such as HSD11B2, NR3C1 and FKBP5. The results suggest that maternal stress \u2014 especially in early pregnancy \u2014 can cause alterations in these genes, which could affect foetal development and the future health of the baby.

\u00c1gueda Castro, first author of the study and CIBERSAM researcher at the University of Barcelona, points out that \u201cthis study reinforces the importance of taking care of the mental health of mothers from the beginning of pregnancy, since stress could leave a biological imprint on the baby\u2019s development through epigenetic mechanisms that we are just beginning to understand\u201d.

IBUB selected this article as the best scientific publication of November 2024 for its innovative approach to prenatal and mental health. Although this is a pilot study, the results open the door to future research and possible interventions to support pregnant women in vulnerable situations from the earliest stages. While these findings need to be replicated in larger studies, this breakthrough underscores the importance of psychological care and emotional support during pregnancy, not only for the mother’s well-being, but also for the long-term health of the baby.<\/p>\n\n\n\n
