Researchers reveal the key role of a protein in placenta formation and fetal growth in mice

Researchers at the Severo Ochoa Center for Molecular Biology (CBM) have identified the protein IRS2 as a critical factor in placental formation and fetal development. The study, conducted using mouse models, demonstrates that the absence of this protein leads to significant developmental alterations during gestation.

The findings highlight a fundamental biological mechanism, as the placenta serves as both a biological barrier and a bridge during pregnancy. By pinpointing the role of IRS2, the research provides new insights into the processes governing healthy fetal growth and the structural integrity of the placenta.
