“We’ve long known that a mammal’s lungs are the last organ to develop in utero before it is baby’s time to exit. Disrupting this normal process (and initiating/inducing labor to start before a baby triggers labor on his/her own) frequently causes a cascade of complications - from difficulty in latch, poor breathing, increased infection, decreased immunity, under development, failure to thrive, and an increase in SIDS.”

“Now, University of Texas Southwestern Medical Center at Dallas researchers have found that it is in fact the fetal lungs themselves which provide the signal to initiate labor.

“Drs. Carole Mendelson, Jennifer Condon and Pancharatnam Jeyasuria published findings that a substance secreted by the lungs of a developing fetus contains the key signal that initiates labor.”

“The protein released from the lungs of a developing mouse fetus initiates a cascade of chemical events leading to the mother’s initiation of labor. This research, which has implications for humans, marks the first time a link between a specific fetal lung protein and labor has been identified, said Mendelson, professor of BioChemistry and Obstetrics and Gynecology and senior author of the study. Their research appears in the Proceedings of the National Academy of Sciences and is currently available online here.”

The initiation of term labor is carefully timed to begin only after the embryo is sufficiently mature to survive outside the womb. Previous studies suggested that the signal for labor in humans may arise from the fetus, but the nature of the signal and actual mechanism was unclear. In this study, researchers found that the key labor triggering substance, surfactant, is essential for normal breathing outside the womb.”
