    Chemical Conversion of Human Conventional PSCs to TSCs Following Transient Naive Gene Activation

    A modified chemical resetting protocol allowed for the fast and efficient conversion of conventional pluripotent stem cells (PSCs) into trophoblast stem cells (TSCs), entailing shutdown of pluripotency genes and full activation of the trophoblast master regulators, without induction of amnion markers.

    Intrinsic Sexual Dimorphism in the Placenta Determines the Differential Response to Benzene Exposure

    Scientists reported that benzene exposure during pregnancy led to maternal immune activation associated with increased fetal resorptions, fetal growth, and abnormal placenta development. They demonstrated the existence of a sexual dimorphic response to benzene exposure in male and female placentas.
