A developing fetus bathes in a mixture of cellular secretions and proteins unique to its mother's uterus. Before fertilization, the pH of uterine fluid helps create a conducive environment for sperm migration, and afterward, its volume supports the embryo as it implants onto the wall of the uterus. Recent evidence suggests that uterine fluid may play another key role in embryonic development: communicating the mother's outside conditions to the fetus, so that the latter can prepare accordingly. A review of this research appears on June 22 in Trends in Molecular Medicine.
