Is Neonatal Uterine Bleeding Responsible for Early-Onset Endometriosis?

Investigators performed a series of experiments to clarify the mechanistic link between neonatal uterine blood (NUB) and/or neonatal endometrium and development of early-onset endometriosis. They retrospectively collected postmortem neonatal endometria and prospectively collected NUB of female babies for the analysis of different biological markers including eMSCs.
