A new study shows that the embryo and the uterine lining conduct an active “conversation” from the very earliest stages of implantation. They engage in a back and forth of tiny packages called extracellular vesicles and lipid droplets, which carry metabolites and signals. Hormones determine what the uterus sends, and one signaling pathway (related to aryl hydrocarbon receptor, [AhR]) appears to assist in determining how hospitable the uterine environment is.
