A team at the Carlos Simon Foundation demonstrated a perfusion system (PUPER, “preservation of the uterus in perfusion”) that kept a donated human uterus alive outside the body for a day. The device maintains tissue via modified human blood circulated through tubing designed to mimic veins and arteries, offering a new platform to study uterine physiology in a controlled ex vivo setting. The foundation said its next goals include maintaining tissue long enough to observe a full menstrual cycle and using the platform to study implantation biology, an area tied to IVF failures. Although the work was presented without publication, collaborators described an ambition to extend perfusion toward longer-term gestational research. For translational medicine, organ perfusion platforms may become tools for disease modeling and therapeutic optimization in reproductive health.
