Parturition gene regulation across multiple cell-types and placental compartments is deciphered at single cell resolution, highlighting the common role of the NFKB pathway in both term and preterm birth.
A time-course of single nuclei RNA-seq of the mouse placenta identifies trophoblast subtypes and the genes, signaling events, and transcriptional networks important for their differentiation, maintenance, and function.
The short-lived tammar wallaby placenta expresses genes resembling eutherian placentas, establishing marsupials as "placental mammals", further, dynamic lactation allows marsupials to compensate for short placentation by expressing key placental genes in the mammary gland.
Comprehensive mass spectrometry analysis of human plasma proteome reveals tissue leakage proteins, describes variability between individual plasma proteomes and demonstrates protein transfer across the placenta during pregnancy.
Loss of Inverted Formin-2 impairs intracellular trafficking and trophoblast invasion, resulting in maternal hypertension and intrauterine growth restriction, which represents a novel model of impaired placental invasion that encompasses critical aspects of the great obstetrical syndromes.
